Experiment Study on Temperature Susceptibility of Cold Recycled Mix with Foamed Bitumen

Abstract:

By using indirect tensile strength test and compression modulus test, the influences of variables, including recycled asphalt pavement (RAP) content and foamed bitumen content, on temperature susceptibility of mechanical properties of cold recycled mix with foamed bitumen (CRMFB) were studied. The results indicated that increase of RAP content had little impact on temperature susceptibility of CRMFB when small quantity of RAP (less than 70%) were contained, while enhanced temperature susceptibility of CRMFB was brought about when a large quantity of RAP (more than 70%) were contained. The mechanical properties, including strength and stiffness, manifested enhanced temperature susceptibility with the increase of foamed bitumen contents. Compared with HMA, CRMFB was obviously less susceptive to temperature.
