Description

沥青摊铺组合物和沥青摊铺方法 Asphalt paving composition and asphalt paving method

技术领域technical field

本发明的领域通常涉及一种沥青摊铺组合物和一种沥青摊铺方法,并且尤其涉及一种含有泡沫润滑物质、沥青结合料、以及集料的组合的沥青摊铺组合物。The field of the invention relates generally to an asphalt paving composition and an asphalt paving method, and more particularly to an asphalt paving composition comprising a combination of a foam lubricating substance, an asphalt binder, and an aggregate.

背景技术Background technique

利用沥青集料混合材料摊铺道路、车道、停车场等是众所周知的。通常,将包含碎石、砂砾、砂等的合适集料混合物在约270°F-370°F的高温下加热,并与同样热的诸如沥青基结合料(asphalt-based binder)(如沥青或沥青加上聚合物)的沥青结合料(bituminous binder)混合,直至集料颗粒被结合料包覆。在所述温度范围制备的摊铺混合经常被称作热拌(hot mix)。通常在远离摊铺现场进行混合,然后,将混合料运送至摊铺地点,并供给摊铺机。随后通常仍在高温下利用其他设备将通过摊铺机施加到路面的沥青和集料的混合料经压路机(roller)压实。最终通过冷却使所述压实的集料和沥青材料变硬。由于摊铺道路或商业停车场的材料用量大,需要考虑为得到适合拌和(mixing)与摊铺所需热量的成本。对于常用结合料,该结合料的热粘度特性将影响提供集料的充分包覆所需要的温度,以及对适合摊铺的环境条件的考虑。结果,设想出许多方法来优化集料包覆和摊铺粘结(pavement binding),而将材料和/或方法的成本降至最低。The use of asphalt aggregate mixes for paving roads, driveways, parking lots and the like is well known. Typically, a suitable aggregate mixture comprising crushed stone, gravel, sand, etc. is heated at an elevated temperature of about 270°F to 370°F and combined with an equally hot asphalt-based binder such as Bituminous binder (asphalt plus polymer) is mixed until the aggregate particles are coated with the binder. Paving mixes prepared in this temperature range are often referred to as hot mixes. Mixing is usually done off-site, and the mix is then transported to the paving site and fed to the paver. The mixture of asphalt and aggregate applied to the road surface by pavers is then compacted by rollers, usually still at elevated temperatures, with other equipment. The compacted aggregate and bituminous material is finally hardened by cooling. Due to the large amount of material used to pave roads or commercial parking lots, the cost of obtaining the heat necessary for mixing and paving needs to be considered. For commonly used binders, the thermal viscosity characteristics of the binder will affect the temperature required to provide adequate coating of the aggregate, as well as considerations of environmental conditions suitable for paving. As a result, many methods have been devised to optimize aggregate wrapping and pavement binding while minimizing material and/or process costs.

可以替代热拌法的有冷拌法,其中,将冷的且潮湿的集料,与热的或冷的结合料混合,该结合料可以是利用适合的表面活性剂将沥青分散在水中得到的乳化液或者是沥青与适合的碳氢化合物溶剂(称一些为例如石脑油、#1油、或#2油)的混合物(通常称作轻制沥青)。乳化的沥青颗粒包覆并与集料粘合,且水分蒸发后仍然存留。使用轻制沥青时,碳氢化合物溶剂以不同速率蒸发,这取决于溶剂的挥发性。不考虑溶剂的挥发性,随后的残留物将作为摊铺材料,其中该沥青组分随除去溶剂的时间而逐渐变硬或变稠。该结合料可以交替地起泡和与集料混合以提高包覆效力。尽管冷拌混合料比热拌混合料便宜,但冷拌混合料的质量通常不及热拌混合料,并且可能结合料的包覆性能也较差,结果导致较差的粘合压实性(cohesive compaction)和耐久性。另外,由于挥发性碳氢混合物溶剂的使用,轻制沥青混合料对环境有更大的影响。一些乳化液也利用除水之外的碳氢化合物溶剂来生产适合于具体应用的材料。An alternative to the hot mix method is the cold mix method, in which cold and moist aggregate is mixed with a hot or cold binder, which may be obtained by dispersing bitumen in water with a suitable surfactant The emulsion is either a mixture of bitumen (often called light bitumen) and a suitable hydrocarbon solvent (called some such as naphtha, #1 oil, or #2 oil). The emulsified bitumen particles coat and bind the aggregate and remain after the water has evaporated. When light bitumen is used, the hydrocarbon solvent evaporates at different rates, depending on the volatility of the solvent. Irrespective of the volatility of the solvent, the subsequent residue will act as a paving material in which the asphalt component gradually hardens or thickens with the time the solvent is removed. The binder can be alternately foamed and mixed with the aggregate to increase coating effectiveness. Although cold mixes are less expensive than hot mixes, cold mixes are usually of lower quality than hot mixes and may also have poorer wrapping properties of the binder, resulting in poorer cohesive compaction) and durability. In addition, lightweight asphalt mixes have a greater impact on the environment due to the use of volatile hydrocarbon solvents. Some emulsions also utilize hydrocarbon solvents other than water to produce materials tailored to specific applications.

近来,为了试图结合热拌法与冷拌法的优点,报道了温拌法。在温拌法的一个实例中,使用了沥青结合料的“软”组分(在给定温度下具有比“硬”组分更低的粘度的组分)和“硬”组分(在给定温度下具有比“软”组分更高的粘度的组分)。该软组分在约110°F-265°F下被熔融并与集料混合,这取决于特定的软组分。然后将热的硬组分与温水混合以产生泡沫,该泡沫与热软组分/集料混合物混合以得到最终的包覆的摊铺材料。尽管温拌摊铺材料可以在比热拌材料更低的温度下摊铺,但温拌混和料的生产却需要一种比生产热拌混合料更广泛且复杂的方法。Recently, in an attempt to combine the advantages of hot mix and cold mix, a warm mix method has been reported. In one example of the warm mix method, the "soft" component of the asphalt binder (the component with a lower viscosity at a given temperature than the "hard" component) and the "hard" component ( components that have a higher viscosity than the "soft" components at a given temperature). The soft component is melted and mixed with the aggregate at about 110°F to 265°F, depending on the particular soft component. The hot hard component is then mixed with warm water to create a foam which is mixed with the hot soft component/aggregate mixture to give the final coated paving material. Although warm-mix paving materials can be paved at lower temperatures than hot-mix materials, the production of warm-mix mixtures requires a more extensive and complex approach than the production of hot-mix mixtures.

尽管集料被包覆,但如果结合料与集料之间粘结不充分,则结合料可以从集料上脱离或“剥落”,引起材料不能保持充分压实并从而降低了路面的总强度。为帮助结合料与集料的粘合,可以用一种抗剥落化合物或材料(如表面活性剂)处理该集料或更通常地是处理沥青结合料,使其作为集料颗粒与沥青结合料之间的粘合剂以实质上减少结合料的脱离。Although the aggregate is covered, if there is insufficient bonding between the binder and the aggregate, the binder can detach, or "peel," from the aggregate, causing the material to not maintain adequate compaction and thereby reducing the overall strength of the pavement . To aid in the bonding of binder to aggregate, the aggregate, or more generally asphalt binder, may be treated with an anti-stripping compound or material (such as a surfactant) so that it acts as aggregate particles with the asphalt binder The adhesive between them can substantially reduce the detachment of the bond.

不考虑所使用的集料/结合料混合方法,包覆摊铺材料必需在运输期间或在摊铺机内时不会硬化在一起,或者不缺乏被压实到适合密度的能力。未充分包覆的集料材料,尽管易于混合和操作,但是可以导致摊铺材料不能保持压实,不能适当地支撑车辆通行,或不能很好地耐磨损和耐气候。Regardless of the aggregate/binder mixing method used, the cladding paving material must not harden together, or lack the ability to be compacted to a suitable density, during transport or while in a paver. Insufficiently coated aggregate material, while easy to mix and handle, can result in a pavement that does not maintain compaction, does not properly support vehicular traffic, or does not resist abrasion and weathering well.

发明内容Contents of the invention

本发明提供了一种合适用于初期建设的沥青摊铺的方法,该方法比传统热拌摊铺方法具有明显更低的拌和、摊铺、及压实温度(温度低30°F-80°F),同时保持传统热拌摊铺的足够的硬化、密度、及耐久性性能。通常,本发明方法包括将可发泡润滑溶液注入热沥青结合料中以形成含有泡沫的沥青基混合物;将该混合物添加入热集料中;使用例如静态混合器进一步混合含泡沫的沥青结合料混合料与集料,以便包覆集料形成摊铺材料;将摊铺材料施加到待摊铺表面;然后将所施加的摊铺材料压实以形成铺设的表面。The present invention provides a method of asphalt paving suitable for initial construction with significantly lower mixing, paving, and compaction temperatures (30°F to 80°F lower than conventional hot mix paving methods) F), while maintaining adequate hardening, density, and durability properties of conventional hot mix paving. Generally, the method of the present invention involves injecting a foamable lubricating solution into a hot asphalt binder to form a foam-containing asphalt-based mixture; adding the mixture to the hot aggregate; and further mixing the foam-containing asphalt binder using, for example, a static mixer mixing aggregate and aggregate so that the aggregate is coated to form a paving material; applying the paving material to the surface to be paved; and then compacting the applied paving material to form the paved surface.

本发明还提供了一种沥青摊铺组合物,包含相对于沥青结合料的重量约0.01wt.%-3wt.%的润滑性物质;约3wt.%-9wt.%的沥青结合料;以及约91wt.%-97wt.%的集料。通常该润滑性物质是约5wt.%-10wt.%的阳离子、阴离子或非离子表面活性剂,例如皂固体,以及约90wt.%-95wt.%的水。可选的润滑性物质可含有的皂固体含量可低至1wt.%,通常实践中上限为30wt.%-40wt.%,以保障皂液的泵送性。The present invention also provides an asphalt paving composition, comprising about 0.01wt.%-3wt.% of lubricating substances relative to the weight of the asphalt binder; about 3wt.%-9wt.% of the asphalt binder; and about 91wt.%-97wt.% aggregate. Typically the lubricious substance is about 5 wt.% to 10 wt.% cationic, anionic or nonionic surfactant, such as soap solids, and about 90 wt.% to 95 wt.% water. The optional lubricating substances may contain soap solids as low as 1 wt.%, and usually practice an upper limit of 30 wt.%-40 wt.% to ensure the pumpability of the soap solution.

该组合物可进一步含有一种抗剥落材料,如伯胺、仲胺、叔胺、亚氨基胺、咪唑啉、或磷酸酯,其中该抗剥落材料中的碳原子数目范围约为7至20。可替换地,所属领域中公知的其他抗剥落材料也适合。当被用于该组合物中时,该抗剥落材料的用量范围按润滑性物质的重量计约为0.1wt.%-10wt.%。The composition may further contain an anti-stripping material, such as primary amine, secondary amine, tertiary amine, iminoamine, imidazoline, or phosphate ester, wherein the number of carbon atoms in the anti-stripping material ranges from about 7 to about 20. Alternatively, other anti-stripping materials known in the art are also suitable. When used in the composition, the anti-stripping material is present in an amount ranging from about 0.1 wt.% to about 10 wt.%, based on the weight of the lubricious material.

具体实施方式Detailed ways

在一种实施方式中,本发明的方法包括将含有润滑性物质的可发泡溶液(foamable solution)注入到热沥青结合料中以形成热的、发泡的混合物;将该热的、发泡的混合物加入加热到比热的、发泡的混合物的温度更高温度的适合集料中;进一步将两者混合以用热的、发泡的混合物包覆热集料以形成热摊铺材料;将该热摊铺材料转移到摊铺机中;利用摊铺机在摊铺温度下将热摊铺材料施加到待摊铺表面;然后将所施加的摊铺材料压实以形成铺设的表面。In one embodiment, the method of the present invention comprises injecting a foamable solution containing a lubricating substance into hot asphalt binder to form a hot, foaming mixture; The mixture is added to a suitable aggregate heated to a temperature higher than that of the hot, foaming mixture; the two are further mixed to coat the hot aggregate with the hot, foaming mixture to form a hot paving material; The hot paving material is transferred to a paver; the hot paving material is applied to the surface to be paved using the paver at paving temperature; and the applied paving material is then compacted to form a paved surface.

使用可发泡润滑性溶液(例如水基泡沫)的一个特点是其被赋予的润滑性使摊铺时摊铺材料的温度明显低于软化结合料所需要的温度(例如大约低30°F-80°F)以提供相似的可建造性。另一个特点是,同样地分散该润滑性材料,含有润滑性物质或润滑材料的水基泡沫比常规乳液或水溶液需要更少的水。因此,不得不将少量的水释放、处理、并最终从摊铺混合料中蒸发。适合的润滑性材料是皂。适合的皂类的非限制性实例包括脂肪酸钠皂、磺酸钠皂、乙氧化壬基酚(ethoxylated non-phenols)、氯化季胺、以及妥尔油(talloil)和精炼妥尔油钠皂或钾皂。也可以使用其他阳离子、阴离子或非离子表面活性剂作为合适的润滑性材料。A feature of using a foamable lubricity solution (such as a water-based foam) is that it imparts lubricity so that the temperature of the paving material during paving is significantly lower than that required to soften the binder (e.g., about 30°F- 80°F) to provide similar buildability. Another feature is that water-based foams containing lubricating substances or lubricating materials require less water than conventional emulsions or aqueous solutions to likewise disperse the lubricating material. Therefore, small amounts of water have to be released, treated, and eventually evaporated from the paving mix. A suitable lubricious material is soap. Non-limiting examples of suitable soaps include sodium fatty acid soaps, sodium sulfonate soaps, ethoxylated non-phenols, quaternary ammonium chlorides, and tall oil and refined sodium tall oil soaps or potassium soap. Other cationic, anionic or nonionic surfactants may also be used as suitable lubricious materials.

本发明提供的显著较低的摊铺温度可以:(1)减少所使用的热能成本,而不会不利地影响摊铺工艺或所得的路面;(2)减少挥发性组分的排放,从而减少空气污染;或(2)允许在摊铺材料中使用实现了“更粘稠”等级的沥青。例如,在相同温拌工艺温度下,可以使用一种与润滑性泡沫混合的更加速效的PG 64-22结合料来替代低粘稠PG 58-28结合料,结果形成与利用PG 58-28结合料产生的热拌路面性能相同的路面。The significantly lower paving temperatures provided by the present invention can: (1) reduce the cost of thermal energy used without adversely affecting the paving process or the resulting pavement; (2) reduce emissions of volatile components, thereby reducing Air pollution; or (2) Allowing the use of "stickier" grades of asphalt in paving materials. For example, at the same warm mix process temperature, a more accelerated PG 64-22 binder mixed with a lubricating foam can be used in place of the less viscous PG 58-28 binder, resulting in a bond that utilizes PG 58-28 The hot mix pavement produced by the material has the same performance as the pavement.

沥青基结合料包括石油基结合料。例如,沥青结合料可包括添加剂,如聚合物材料。适合的沥青基或沥青结合料包括遵循ASTMD-6373、D-3387、或D-946的那些结合料。但是,也可以使用一些本质上遵循但不完全遵循ASTM D-6373、D-3387、或D-946的沥青结合料。该集料可包含再生沥青路面(RAP)。Asphalt-based binders include petroleum-based binders. For example, an asphalt binder may include additives, such as polymeric materials. Suitable asphalt-based or asphalt binders include those conforming to ASTM D-6373, D-3387, or D-946. However, some asphalt binders that essentially but not fully comply with ASTM D-6373, D-3387, or D-946 may also be used. The aggregate may comprise recycled asphalt pavement (RAP).

在本发明的方法的一种实施方式中,可发泡溶液是含有由皂制成的润滑性物质的水溶液。该摊铺材料含有约91wt.%-97wt.%的集料和约3wt.%-9wt.%的沥青基结合料。相对于所用沥青基结合料的重量,用于给定量的集料中的皂固体用量约为0.01wt.%-3wt.%。In one embodiment of the method of the invention, the foamable solution is an aqueous solution containing a lubricious substance made of soap. The paving material contains about 91 wt.% to 97 wt.% aggregate and about 3 wt.% to 9 wt.% asphalt-based binder. The amount of soap solids used in a given amount of aggregate is from about 0.01 wt.% to about 3 wt.%, relative to the weight of asphalt-based binder used.

将该热的、发泡的沥青结合料混合料加热到低于形成传统热拌混合料所用温度的温度。依据使用的特定沥青结合料,适合的温度范围约为180°F-340°F。类似地,将适合的集料加热到约180°F-300°F范围内的温度并在温度约180°F-300°F范围内将该热摊铺材料加热并混合。将该摊铺材料在温度约170°F-290°F范围内进行摊铺,并在温度约150°F-270°F范围内进行压实。该可发泡皂溶液可以处于不会使液体冻结、沸腾、或有害影响泡沫的任何温度,但优选其温度范围约为80°F-150°F。The hot, foamed asphalt binder mixture is heated to a temperature lower than that used to form a conventional hot mix. A suitable temperature range is approximately 180°F to 340°F, depending on the particular asphalt binder used. Similarly, a suitable aggregate is heated to a temperature in the range of about 180°F to 300°F and the hot paving material is heated and mixed at a temperature in the range of about 180°F to 300°F. The paving material is spread at a temperature in the range of about 170°F to 290°F and compacted at a temperature in the range of about 150°F to 270°F. The foamable soap solution can be at any temperature that does not cause the liquid to freeze, boil, or adversely affect the lather, but preferably has a temperature in the range of about 80°F to 150°F.

这种实施方式可通过将可发泡溶液注入热沥青结合料;将该热的、发泡的混合料加入到适合的集料以及在作业地点或附近就地混合以形成热摊铺材料来实施。本发明的一个优点是,混合沥青结合料与集料所用液体的体积显著减小,这样可以方便就地施工并减少了运输大量水的必要。This embodiment can be implemented by injecting a foamable solution into a hot asphalt binder; adding the hot, foamable mix to a suitable aggregate and mixing it in situ at or near the job site to form a hot paving material . An advantage of the present invention is that the volume of liquid used to mix the asphalt binder and aggregate is significantly reduced, which facilitates on-site construction and reduces the need to transport large quantities of water.

在本发明方法的另一种实施方式中,该水溶液包含约30wt.%的皂固体和约70wt.%的水;该沥青结合料含有PG58-28沥青;该摊铺材料含有约94.5wt.%的集料和约5.5wt.%的PG58-28沥青结合料;以及相对于所用沥青结合料的量,所用皂固体的量约小于1wt.%。对于这种特定结合料,该热的、发泡的沥青结合料混合料被加热到约为240°F-340°F的温度;该适合的集料被加热到范围约为180°F-300°F的温度;并且加热该热摊铺材料并在温度范围约180°F-300°F下进行混合。该摊铺材料在范围约为170°F-290°F的温度下进行摊铺,并在范围约150°F-270°F的温度下进行压实。In another embodiment of the method of the present invention, the aqueous solution comprises about 30 wt.% soap solids and about 70 wt.% water; the asphalt binder comprises PG58-28 asphalt; and the paving material comprises about 94.5 wt.% aggregate and about 5.5 wt.% of PG58-28 asphalt binder; and the amount of soap solids used is less than about 1 wt.% relative to the amount of asphalt binder used. For this particular binder, the hot, foamed asphalt binder mix is heated to a temperature of about 240°F-340°F; the suitable aggregate is heated to a temperature in the range of about 180°F-300°F °F; and heating the hot paving material and mixing at a temperature in the range of about 180°F-300°F. The paving material is paved at a temperature ranging from about 170°F to 290°F and compacted at a temperature ranging from about 150°F to 270°F.

在另一种实施方式中,该水溶液含有约30wt.%的皂固体和约70wt.%的水;沥青结合料含有PG 64-22沥青;该摊铺材料含有约94.5wt.%的集料和约5.5wt.%的PG 64-22沥青结合料;以及相对于所用沥青结合料的量,所用皂固体的量约小于1wt.%。对于这种特定沥青结合料,该热的、发泡的沥青结合料混合物被加热到温度约为240°F-340°F;该合适集料被加热到范围约为180°F-300°F的温度;并且加热该热摊铺材料并在范围约为180°F-300°F的温度下进行混合。该摊铺材料在范围约为170°F-290°F的温度下进行摊铺,并在范围约为150°F-270°F的温度下进行压实。所属领域中的普通技术人员将明了,热的、发泡的沥青结合料混合料与适合的集料可以在更高温度下进行加热并混合且摊铺材料也可以在更高温度下进行摊铺和压实,而不会对摊铺材料的性能产生负面影响,但这样做在热能支出方面将更高。In another embodiment, the aqueous solution contains about 30 wt.% soap solids and about 70 wt.% water; the asphalt binder contains PG 64-22 bitumen; the paving material contains about 94.5 wt.% aggregate and about 5.5 wt. wt.% of PG 64-22 asphalt binder; and the amount of soap solids used is less than about 1 wt.% relative to the amount of asphalt binder used. For this particular asphalt binder, the hot, foamed asphalt binder mixture is heated to a temperature of approximately 240°F-340°F; the suitable aggregate is heated to a range of approximately 180°F-300°F and heating the hot paving material and mixing at a temperature ranging from about 180°F to 300°F. The paving material is paved at a temperature ranging from about 170°F to 290°F and compacted at a temperature ranging from about 150°F to 270°F. Those of ordinary skill in the art will appreciate that hot, foamed asphalt binder mixes and suitable aggregates can be heated and mixed at higher temperatures and paving materials can also be laid at higher temperatures and compaction without negatively affecting the performance of the paving material, but doing so will be higher in terms of thermal energy expenditure.

通常,沥青温度需要高于集料温度。根据沥青等级,沥青应为325°F或更高以使其可以被泵送并发泡。因为集料占混合料重量的约90%,因此集料温度基本上控制着混合料的温度。集料温度需要被控制在温拌温度约180°F-300°F范围内。当将集料与粘稠结合料或含有聚合物的结合料混合时,常规集料以及混合料的温度可高达350°F,这是热拌,但利用本发明,在相同集料与结合料的情况下,集料和混合料的温度可被降至300°F,且不会对得到的路面性能造成负面影响,这被认为是温拌。Typically, the asphalt temperature needs to be higher than the aggregate temperature. Depending on the bitumen grade, the bitumen should be 325°F or higher to allow it to be pumped and foamed. Since the aggregate constitutes about 90% by weight of the mix, the temperature of the aggregate essentially controls the temperature of the mix. Aggregate temperature needs to be controlled within the warm mix temperature range of approximately 180°F - 300°F. When mixing aggregates with viscous binders or binders containing polymers, the temperature of conventional aggregates and mixes can be as high as 350°F, which is hot mix, but with the present invention, in the same aggregate and binder In cases where aggregate and mix temperatures can be reduced to 300°F without negatively affecting the resulting pavement performance, this is considered warm mix.

在本发明方法的另一种实施方式中,可发泡溶液进一步含有抗剥落材料。适合的抗剥落材料的非限制性实例有伯胺、仲胺、叔胺、亚氨基胺、咪唑啉、或磷酸酯,这些材料中碳原子数目的范围约为7至20。In another embodiment of the method of the present invention, the foamable solution further contains an anti-stripping material. Non-limiting examples of suitable anti-stripping materials are primary amines, secondary amines, tertiary amines, iminoamines, imidazolines, or phosphate esters, where the number of carbon atoms in these materials ranges from about 7 to about 20.

在本发明方法的另一种实施方式中,水溶液进一步包含抗剥落材料以使可发泡溶液含有约30wt.%的皂固体、约5wt.%的抗剥落材料、以及约65wt.%的水。In another embodiment of the method of the present invention, the aqueous solution further comprises an anti-stripping material such that the foamable solution contains about 30 wt.% soap solids, about 5 wt.% anti-stripping material, and about 65 wt.% water.

一种对摊铺的路面材料性能的测试是通过测量承载特定重量载荷的轧辊(压路机,roller)反复碾压路面而在材料上引起特定深度的车辙的反复次数来模拟车辆交通压力。对由本发明方法制造的压实材料的测试是通过使用称为汉堡车辙试验仪(Hamburg WheelTracking(“HWT”),又称PMW Wheel Tracker试验仪)完成的,上述仪器由Precision Machine and Welding,S alina,KS提供。在干燥条件下测试已压实材料时,达到10mm车辙深度所需要的汉堡碾压(Hamburg passes)次数用作对比评价。测试条件为1581b.车轮载荷,利用热空气在测试温度下每分钟碾压52次以达到样本测试温度。通常,当所有其他变量均基本上相同时,碾压次数越多,所期望的摊铺混合料的性能越好。当样品经受这些测试条件时,基于所提供的结果,本领域的普通技术人员以及熟悉HWT的人员将识别出适合于特定应用的摊铺材料。A test of the performance of paved pavement materials is to simulate vehicle traffic pressure by measuring the number of times a roller (roller, roller) carrying a specific weight load repeatedly rolls the pavement to cause ruts of a specific depth on the material. Testing of the compacted material produced by the method of the present invention was accomplished by using what is known as the Hamburg Wheel Tracking ("HWT"), also known as the PMW Wheel Tracker tester, which is manufactured by Precision Machine and Welding, Salina , provided by KS. The number of Hamburg passes required to achieve a rut depth of 10 mm was used as a comparative evaluation when testing compacted material in dry conditions. The test condition is 1581b. wheel load, using hot air at the test temperature to roll 52 times per minute to reach the sample test temperature. In general, all other variables being substantially equal, the greater the number of passes, the better the desired properties of the paving mix. Based on the results presented when samples are subjected to these test conditions, one of ordinary skill in the art, as well as those familiar with HWT, will identify suitable paving materials for a particular application.

在表1中,对于处理和测试的特定结合料而言,混合温度范围为270°F-280°F、以及压实温度约为275°F或更高的实施例被认为是传统的热拌;混合温度范围为230°F-235°F、以及压实温度范围为215°F-220°F的实施例被认为是温拌。因此,实施例1、4、6、7、和10是热拌,而其他实施例对于结合料而言则是温拌。In Table 1, for the particular binder processed and tested, examples with a mixing temperature ranging from 270°F to 280°F and a compaction temperature of about 275°F or higher are considered conventional hot mix ; Examples having a mixing temperature in the range of 230°F to 235°F and a compaction temperature in the range of 215°F to 220°F are considered warm mix. Thus, Examples 1, 4, 6, 7, and 10 were hot mix, while the other examples were warm mix for the binder.

如数据所示,通常,温拌时使用与热拌相同的结合料不能产生相同的结果,但确实可以提供一种可接受的摊铺材料。温拌具有较低的汉堡碾压次数。次数少的原因可能是由于以下事实:在温拌工艺中由于较低的拌和温度和较短的熟化时间,结合料的老化和熟化并不那样充分,正如比较实施例1、2、和3所示出的那样。实施例1、6、和7说明熟化在很大程度上提高了热拌的性能,而实施例16、17、和18也说明了即使皂量下降,熟化也能促进性能提高。实施例1和4说明,热拌中仅添加抗剥落剂并不能改善路面。实施例4在稍高温度下进行测试,并表明抗剥落材料提高了性能。所有他条件不变,通过将测试温度提高8℃,可使碾压出10mm车辙深度的碾压次数下降多达50%。实施例8和9说明,本发明使用含有比PG58-28更稠的PG 64-22作为结合料能够导致改善性能。实施例14和15说明,本发明使用PG 64-22、15%的RAP、和30分钟的熟化,能达到最佳的路面性能。数据显示,可使用较大初始稠度的结合料来生产温拌料,以产生与用于生产热拌料的粘稠性较差的结合料的性能近似相等的性能。PG 58-28结合料的粘稠性比PG 64-24结合料要差,但如数据所示,在温拌中使用PG 64-22结合料产生汉堡结果(Hamburg result),其近似相同于热拌中的PG 58-28的结果。因此,使用本发明,能够用PG 64-22替代PG 58-28,结果得到适合的路面。As the data show, generally, using the same binder for warm mix as hot mix does not yield the same results, but does provide an acceptable paving material. Warm mix has a lower number of hamburger rolls. The reason for the low number of times may be due to the fact that in the warm mixing process, due to the lower mixing temperature and shorter curing time, the aging and curing of the binder is not so sufficient, as shown in comparative examples 1, 2, and 3 as shown. Examples 1, 6, and 7 illustrate that aging improves hot mix performance to a large extent, while Examples 16, 17, and 18 also illustrate that aging can promote improved performance even with reduced soap levels. Examples 1 and 4 show that only adding anti-stripping agent in hot mixing can not improve the road surface. Example 4 was tested at a slightly higher temperature and shows that the anti-stripping material improves performance. All other conditions being the same, by increasing the test temperature by 8°C, the number of rolling times to roll out a 10mm rut depth can be reduced by as much as 50%. Examples 8 and 9 illustrate that the use of the present invention using a binder containing PG 64-22 which is thicker than PG 58-28 can result in improved performance. Examples 14 and 15 illustrate that the present invention achieves the best pavement performance using PG 64-22, 15% RAP, and 30 minutes of curing. The data show that warm mixes can be produced using binders of higher initial consistency to produce approximately equal properties to those of less viscous binders used to produce hot mixes. The PG 58-28 binder was less viscous than the PG 64-24 binder, but as the data show, using the PG 64-22 binder in warm mix produced a Hamburg result that was approximately the same as the hot mix. Results of PG 58-28 in the mix. Thus, using the present invention, it is possible to replace PG 58-28 with PG 64-22, resulting in a suitable road surface.
