In the dissertation, a new stabilization method, equal-density method was adopted to prepare modified asphalts with storage stability at high temperature. In this method, a compound was prepared by premixing polymer and filler, and the compound was mixed with asphalt to prepare Polymer-Modified Asphalt by changing the ratio of polymer and filler. The asphalts with good storage stability were formed with the addition of filler, by regulating the density difference between polymer and asphalt. With identifying the effect of composition factor and the technique conditions on mechanical properties of polymer/filler compound and the molecular distribution of the polymer, identifying the effect of composition factor and the technique conditions on the properties and structure of polymer/filler modified asphalt, Styrene-Butadiene-Styrene copolymer, Low Density PolyEthylene, Styrene-Ethylene-Butadiene-Styrene block copolymer modified asphalts with good storage stability and performance were prepared. Rheological method, gel content analysis and swelling measurement were adopted to elucidate the interaction between the polymer and filler. Filler reduced the difference between the polymer and asphalt with the premixing technique, which led to the improvement of the storage stability of the modified asphalts. The thermo-oxidative aging process of base asphalt and PMA were studied and the effect of antioxidant additives on the base asphalt and PMA were analyzed.
