Definitions

  • the present invention relates generally to a method and a mixer for preparing an asphalt mixture, for subsequent in- termediate storage and future spreading on a road or the like.
  • the present invention relates specifically to a method and a mixer for preparing a so called hot asphalt mixture.
  • Asphalt is basically a mixture of stone material/aggregate and a binder, and is used as a surface course, binder course and/or base course on for example roads, airports, parking sites, etc.
  • Conventional preparing of so called hot asphalt mixture embrace warming the aggregate up to approxi- mately 16O 0 C and that all the aggregate is placed in a mixer whereupon heated binder is provided in liquid form. Thereafter, the asphalt mixture is kneaded, at a process temperature of approximately 160 0 C, to its final consistency, for subsequent intermediate storage and future spreading.
  • Hot asphalt mixture has by tradition in general better characteristics than previous attempts with preparing warm asphalt mixture (temperature of preparing approximately 70-120 0 C) and so called cold asphalt mixture (temperature of preparing below 70 0 C) , however, the preparing of hot asphalt mixture is very energy consuming, and also large amounts of nitric oxides and carbon dioxide emanates during the preparing and spreading of hot asphalt mixture, which is harmful to the environment and provide a worse working environment for the workers spreading the asphalt. Thus, for a time back the aim has been to lower the preparing temperature, near to the lower limit for hot asphalt mixture, without compromising on the quality of the spread asphalt, and thus to prepare hot asphalt mixture having similar characteristics as conventional hot asphalt mix- tare prepared ac approximately 160 0 C.
  • EP 1,398,351 Bl disclose a method directed towards preparing warm and hot asphalt mixture, in which method all the aggregate is loaded into a mixer, a foaming agent in the shape of a polymerized fatty acid is added to a heated bitu- men, whereupon the resulting binder mixture is added to the aggregate as a foam.
  • US 2005/0018530 Al discloses a method directed to the preparing of asphalt mixtures in the lower area of hot asphalt mixture, in which method the aggregate is added to the asphalt mixture in two portions.
  • a primary object of the present invention is to provide an improved method for preparing an asphalt mixture of the initially defined type, which provides an asphalt mixture, prepared near to the lower limit of hot asphalt mixture, having similar or better characteristics than conven- tional hot asphalt mixture, for instance regarding durability, adhesiveness, the presence of cavities, stiffness/toughness, etc., of the spread asphalt.
  • the primary object is attained by means of the initially defined method, which is characterized by the steps of, loading a dried aggregate comprising stone material principally free from filler into the mixer, thereafter loading a foamed binder mixture into the mixer that contains said dried aggregate, the binder mixture is foamed when it leaves a prefoaming chamber and is loaded into the mixer, whereupon said aggregate and said foamed binder mixture is mixed, and thereafter a filler is loaded into the mixer, whereupon final mixing of the asphalt mixture takes place.
  • the present invention is based on the insight that it is crucial for the asphalt which is made from the asphalt mixture that the binder mixture is allowed to bond to the stones of the aggregate in thick layers/coatings before the heavily absorbing filler is added to the asphalt mixture.
  • the binder mixture comprises bitumen, an ad ⁇ hesion agent in the form of a fatty acid and a foaming agent in the form of water, whereupon a strong and long lived foam is provided, which contributes to a asphalt mixture which is easy to work and which bonds to the stones of the aggregate in thick layers before the filler is added.

  • a predetermined amount of aggregate 1 from the respective raw material silo 2 is loaded onto a conveyer belt or the like, whereupon the aggregate is directed towards a drier 3.
  • the drier 3 is constituted by a coun- terflow rotary drier, which has a slight inclination downwards and also rotates during operation.
  • Aggregate 1 is feed into a first upper end of the drier 3 and is discharged from a second lower end, as a consequence of the rotary motion of the counterflow rotary drier during operation.
  • the aggregate 1 is exposed to heat and is heated to a temperature between 100 and 13O 0 C, preferably approximately 120 0 C, whereupon the aggregate 1 is dried.

Furthermore, the adhesion agent has a lubricating effect in the asphalt mixture when it is prepared in the mixer 15 as well as when the asphalt mixture is spread.

  • the filler 6 that is loaded into the mixer 15 under the preparing consists of at least partly of the same material as the aggregate, usually granite or the like, but may also comprise other material. For instance, so called stone rich aggregate, from which a small amount of filler may be separated in the heating process seep, may require that a certain amount of limestone filler is added to the filler 6 that is loaded into the mixer 15.
  • the limestone filler may conventionally represent maximum 50% of the filler 6 that is loaded into the mixer 15.
  • Other additive to the filler 6 that is loaded into the mixer 15 may be cellulose filler, which preferably constitute maximum 1 percentage per weight of the total weight of the asphalt mixture.
  • the advantage of adding the filler 6 after the foamed binder mixture and the aggregate principally free from filler are mixed, is that thick binder coatings/layers are obtained on each stone of the aggregate, thereafter the filler 6 enters these coatings and absorb that part of the binder mixture that has not attached to the stones of the aggregate. This results in a dense asphalt in which the rain water does not leak through and runs the risk of breaking the asphalt or wash the binder off.
  • an asphalt mixture is obtained which provide a packed asphalt having a cavity extent of approximately 3%.
  • One other advantage of the present invention is that it has been shown that the process temperature in the mixer 15 does not require to be raised as usual when recycled asphalt is added to the asphalt mixture during the preparing.
