Characteristics of Cast-in-Place Asphalt Mixtures
2012-07-20
Pourable asphalt mixtures differ from other types in that they consist of high-content, high-viscosity asphalt, a high dosage of mineral powder, and sometimes fiber materials, all combined with an appropriate amount of aggregate.
In cast-in-place asphalt mixtures, coarse aggregate particles are suspended in an asphalt mastic and cannot interlock with each other to form a skeletal structure. The strength of such mixtures primarily depends on the cohesive forces generated by the interaction between the asphalt and the filler materials. These mixtures are essentially free of voids, impermeable, and exhibit excellent resistance to erosion. They also have high deformation capacity and are less likely to develop cracks at low temperatures. In Japan, cast-in-place asphalt concrete is referred to as high-temperature mixed and paved asphalt concrete; in the United Kingdom, to enhance the skid resistance of this type of pavement, pre-mixed asphalt-aggregate chips are scattered onto the freshly poured mixture while it is still hot, and then compacted to ensure that the chips become embedded within the mix.
