摘要
通过对比试验 ,对宽域沥青 (Multiphalte)的各项性能指标进行了测试 ,并按美国 SHRP的PG分级指标进行测试 ,其性能达到 PG76 - 2 8并满足中国 EVA、PE改性沥青的指标要求 ,具有较好的高温稳定性和温度敏感性。通过宽域沥青混合料的配合比设计试验与各项性能测试 。
The performance indexes of multiphalte were tested through contrast experiments and according to the performance grading(PG) indexes of SHRP, USA. Results show that the multiphalte's performance reaches PG76-28 standard and meets the standard of EVA? PE modification asphalt of China.It has good high temperature stability and temperature sensibility.On the tests of mixture design and all the performance indexes of multiphalte mixture,the results suggest its high temperature stability and lower temperature performance is acceptable.11 tabs, 5 refs.
