三种沥青混合料抗车辙添加剂的性能综合比较

为了客观评价不同抗车辙剂的性能和效果,通过高温蠕变、车辙试验、冻融劈裂、低温小梁弯曲等多种试验,综合评价了3种抗车辙剂对沥青混合料高温、低温、抗水损坏性能的影响,表明各种抗车辙剂对于高温性能的提高均有明显效果,对于低温、抗水损坏性能的影响程度不同;同时国产抗车辙添加剂的综合性能与2种国外产品相当。

Comprehensive Comparison of Three Kinds of Asphalt Mixture Anti-rutting Additives

For evaluation of different anti-rutting addtives,through high temperature slow change test,wheel rut test,freezing and thawing cleavage test,low temperature curving test,this article evaluates the influence to high temperature,the low temperature,the anti-water damage performance of three kinds of anti-rutting additives to the asphalt mixture,and indicates that each kind of anti-rutting additives has the tangible effect regarding the high temperature performance＇s enhancement,regarding the low temperature,the anti-water damage performance＇s influence is different.And the overall performance of the domestically produced anti-rutting additive is as good as two foreign products.
