| 摘 要： | 为研究矿物纤维在SMA沥青混合料中的适用性,从纤维的吸油率、拌和和易性以及掺加矿物纤维的SMA沥青混合料的路用性能等几个方面开展研究工作,并与一般的木质素纤维进行比较。研究发现矿物纤维较木质素纤维吸油率低,分散较为困难,采用矿物纤维的SMA沥青混合料的性能满足设计规范要求。建议SMA沥青混合料纤维稳定剂的选用应结合经济和施工水平综合考虑。

| Abstract: | In order to evaluate the performance of mineral fiber in SMA mixture,the paper analyses the oil adsorption, construction workability and pavement performance of SMA mixture with mineral fiber. A comparison is also carried out with the mixture with cellulose fiber. The test results show that mineral fiber has low oil adsorption and is difficult to separate. The mixture with mineral fiber has good pavement performance and the economy and the construction level sould be considered when choosing fiber in SMA. |
