  • Patent number: 10954390
    Abstract: The low temperature cracking and high temperature rutting of polymer-modified asphalt concrete pavement can be reduced. The composite includes asphalt and at least one polymer that expands at low temperature, triggered by cooling-induced tensile stress, to reduce thermal cracking. The composite includes at least one polymer that expands at high temperature, so that the composite recovers after compression induced by traffic loading at higher temperatures, thereby reducing rutting. The system reduces thermal stress, and reduces or even eliminates thermal cracking and rutting. Shape memory polymers (SMPs) are used to improve asphalt compositions so that they better resist both thermal cracking and rutting. The SMP(s) can be incorporated into the asphalt, or a portion of fine aggregates can be replaced with SMP particles or SMP fibers, or aggregate replacement and asphalt modification can be combined.
