Low density polyethylene(LDPE) modified asphalt dispersed finely in asphalt is prepared by two step blending process.Dynamic viscoelastic analysis of the blends show that part of crystallization of LDPE is disturbed by penetration of part components of asphalt into interior of LDPE particles. Microstructure of LDPE modified asphalt exhibits some combination of LDPE and asphalt.Structure and property tests show that LDPE improved the high temperature resistant performance of matrix asphalt… CONTINUE READING
