摘要
从提高浇注式沥青混合料热稳性出发,采用高性能的改性沥青与天然沥青进行复合改性沥青,在确保浇注式的施工性能及抗低温开裂性能的同时,大大提高了浇注式沥青混合料的热稳性。
In order to improve the heat resistance of gussasphalt, the high performance modified asphalt, together with the natural bitumen, is used for making the multi - modified asphalt, which greatly improves the heat resistance of gussasphalt while the construction performance and cracking resisitance at low temperature of gussasphalt are ensured.
