  • the present invention relates to a method for rejuvenating a bitur ⁇ en containing composition.
  • BV at the Hague discloses a rejuvenating agent and a method for recycling asphalt.
  • a rejuvenating agent a composition is used comprising bitumen and palm oil.
  • Examples of other known rejuvenating agents from the prior art are paraffins and rape seed oil etc.
  • these agents have just like palm oil the important disadvantage that they render the bitumen too soft, whereby the viscosity of the bitumen containing composition, such as for example asphalt, becomes also too low.
  • the viscosity of the bitumen containing composition such as for example asphalt
  • these agents are poorly mixable with the bitumen.
  • compositions In the prior art it is known to recycle asphalt and other bitumen containing compositions.
  • the compositions usually are milled and added to new compositions to be prepared or are recycled as such while adding suitable additives.
  • new fresh bitumen has to be added to the composition to guarantee the processability and quality (durability, life) of the composition.
  • compositions being comprised of solely recycled bitumen containing material with good properties for use in practice showed to be impossible up till present.
  • Such compositions exist these are applied where the inferior properties thereof are not important.
  • machined asphalt is reused without the addition of fresh bitumen for road side reinforcement edges.
  • Such a material is however fully unsuitable for use as new road surface.
  • the amount of available suitable bitumen is decreasing considerably in recent years.
  • Bitumen containing compositions are very sensitive to aging and therefore have to be replaced in time as the properties in time degrade.
  • Ageing of bitumen containing compositions can be caused by different mechanisms, comprising oxidation, evaporation of substances, UV-attack, exudation and orientation. In this process partly maltenes are converted into asphaltenes, whereby the material gets more brittle. By ageing the favorable properties for processing and application decrease in quality. The compositions frequently become harder, more brittle, less flexible and in time less and less recyclable.
  • Bitumen is for the majority used in asphalt for road construction. By erosion and weather influences asphalt ages relatively quick and usually asphalt has to be renewed within ten years. Hereto the asphalt is removed from the road surface and decreased in size by milling. This milling product is recycled with new asphalt preparation in a small amount. Real recycling of such milling asphalt while maintaining good asphalt properties is nowadays only possible with very high cost by for example the additional of special chemical substances or fresh bitumen.
  • the present invention intends to meet said need and thereto provides a method for rejuvenating a bitumen containing composition, said method comprising adding a raw (untreated) cashew nut shell liquid (CNSL) to the bitumen containing composition.
  • CNSL cashew nut shell liquid
  • bitumen in the composition is rejuvenated such that the properties thereof are improved and the bitumen is again made suitable for the usual applications thereof.
  • the rejuvenated bitumen is even superior to freshly prepared bitumen with regard to certain properties.
  • CNSL is a natural product, which has huge technical advantages.
  • CNSL is a resin which is extracted from the shells of cashew nuts and is available in large quantities. This resin virtually completely consists of phenolic compounds with a chain length of substantially 15 C-atoms with varying unsaturation degrees, meta-substituted in the phenol ring.
  • the rejuvenation of bitumen is intended to mean that the properties of used bitumen are improved such that the bitumen regains properties which are better than these of the used bitumen, advantageously comparable with those of fresh bitumen, and in particular better than those of fresh bitumen.
  • Per se EP-A-1 642 935 discloses a bitumen containing binding agent used in for example road construction, for surface treatments an asphalt mixing system method.
  • Said agent comprises a bitumen basis and a flux agent for example a reactive flux agent such as cashew nut shell liquid (CNSL), cardol or cardanol.
  • CNSL in this respect relates to the distillation product of raw CNSL and not to the resin directly obtained by pressing or extracting the shells of cashew nuts.
  • the distillation product is a reactive product intended to alter properties in a reactive manner.
  • the raw CNSL according to the invention does not adjusts the properties of the bitumen containing composition in a reactive manner but in a physical manner.
  • CNSL substantially refers to the 'reactive' distillation product thereof and not to the 'non-reactive' raw cashew nut shell liquid obtained by pressing or extracting cashew nut shells, nor the 'non-reactive' distillation residue according to the invention.
  • the use of the non reactive raw CNSL implies the possibility of recycling of the bitumen containing composition which has great advantages from the point of view of economics, but also environmentally.
  • the raw CNSL resin to be added is preferably subjected to a temperature treatment at about 50 0 C to 380 0 C. By this temperature treatment the CNSL is rendered less irritating, such that it can be processed without disadvantageous consequences for the processor.
  • the time during which the CNSL resin is heated to about 50 0 C to 380 0 C is at least 15 min and more preferably at least 30 min.
  • the temperature treatment is already taking place during the rejuvenation of the bitumen containing composition.
  • asphalt is prepared at an elevated temperature of about 180 0 C and the temperature treatment will take place during preparation of the asphalt.
  • the temperature treatment can take place before as well as after the addition of the CNSL resin to the bitumen containing composition.
  • the raw CNSL resin to be added is subjected to a temperature treatment at about 150 0 C to 380 0 C.
  • the CNSL resin has a viscosity which is comprised between 1 ,000 and 300,000 mPa.s "1 .
  • the CNSL resin has a viscosity which is comprised between 1 ,000 and 30,000 mPa.s 1 , preferably between 1 ,000 and 10,000 mPa.s '1 , more preferably between 1 ,000 and 2,500 mPa.s "1 , and the most preferred viscosity is substantially 1 ,500 mPa.s 1 .
  • a CNSL resin with such a viscosity is particularly suitable for rejuvenating bitumen.
  • the CNSL resin has an average saturation factor of 1 to 5, and preferably 1.2 to 1.3.
  • the CNSL used according to the invention consists mainly of a mixture of polymerization products of 3-pentadecenylphenol and 3- pentadecadienylresorcinol, in the form of an alkylphenol resin being liquid at room temperature.
  • the chain length is about 13-16 carbon atoms
  • bitumen containing composition is selected from: bitumen, asphalt, insulating material, shore covering material and anti-drum plates.
  • bitumen containing compositions can be rejuvenated by the addition of the raw CNSL according to the invention such that these become suitable for recycling without the addition of fresh bitumen, although this addition of course is not excluded.
  • bitumen containing composition can additionally be made up with one or more of the following substances: resin whether or not vegetable, oil whether or not vegetable, paraffins, polymers such as EVA, SBS, APP, PE metallocenes and synthetic waxes.
  • the invention further provides a bitumen containing composition which has been rejuvenated by application of the method according to the invention.
  • the rejuvenated bitumen containing composition is selected from: asphalt, insulating material, roofing, shore covering material, anti-drum plates.
  • Example 1 Method for rejuvenating bitumen containing recycled roof shingles.
  • the roof shingles used were roof webs which for about 20 years had laid on roofs on different locations in The Netherlands.
  • the origin of the roof bitumen was varying as apart from renovation debris it also concerned demolition debris.
  • This aged bitumen roofing consisted of 50% by weight of bitumen with atactic polypropylene (App) (polymer modified bitumen) and for the remainder of fillers and split material. This shingles were reduces in size mechanically.
  • test pieces of the samples with 10% up to and including 25% CNSL addition were applied on a roof in Heerhugowaard (NL).
  • NL Heerhugowaard
  • the shingles with 10% and 15% CNSL addition to the recycled aged roof bitumen showed less good processing properties.
  • the shingles were at an outside temperature of 12 0 C too rigid during processing.
  • the shingles with an addition of 20% showed the best processing properties.
  • This composition resembles most that of a shingle based on new bitumen (production 2008).
  • roof bitumen 1 part raw CNSL (on a weight basis).
  • the origin of the roof bitumen was the same as the tests described earlier.
  • the aged road construction bitumen originated from milling different asphalt roads. This milled asphalt was heated in a heating drum and mixed with the roof granulate. De roof granulate was first premixed with the CNSL resin and then cold added to the preheated minerals and the milled asphalt in the asphalt mixer. This mixture was mixed homogeneously and additionally tested, as shown in Table 3.
  • Roof granulate This was a mixture of different bituminous roofings derived from demolition labor and roofing companies in replacing old bituminous roofs. This demolition debris was milled and homogenized. This substantially consisted of bitumen being APP modified with minerals and glass fiber reinforcement. During milling a granulate was obtained which could vary in size from 0,5 mm to 15 mm. Milled asphalt: This was asphalt granulate obtained by milling aged or damaged asphalt road. Milling was performed selectively such that different qualities were kept separate in for example DAB, STAB, ZOAB and the like. After milling the granulate was classified by sieving.
  • Raw CNSL This was obtained by pressing and/or extracting the shells of cashew nuts left over after peeling.
