Abstract
Abstract By in house experiment a study is made on the asphalt modifying agent made from plastic basin, stool and bucket so on domestic waste plastic and the effect of modifying asphalt. The result shows: (1) the modifying agent made of waste plastic can considerably improve softening point of asphalt and reduce needle penetration; (2) for the modifying asphalt made from waste plastic by different making method its storage stability differs and PMA modifying asphalt made from waste plastic grain by plastic extruder has severe segregation and poor storage stability. But the PMB waste plastic modifier specially made under given study can not only improve the high temperature stability of asphalt but also no segregation of modifying asphalt and has sound storage stability; (3) Waste plastic can apparently improve the degree of stability of asphalt mixture and the effect of stability degree improvement of PMB is better than that of PMA and the improvement of flow value is not obvious. The achievement of study...
