摘　　要：通过湿轮磨耗试验和负载轮粘砂试验，研究了添加纤维与橡胶粉稳定剂在微表处混合料中的适用性。结果表明：微表处混合料可以通过添加纤维、橡胶粉或者两者的复合稳定剂来增大混合料的用油量；添加了纤维的微表处混合料，其耐磨耗性能有很大提高；橡胶粉用量不宜过多，应控制在5％左右以防止碾压变形；4％橡胶粉＋0．02％纤维的复合稳定剂对微表处混合料改善效果较好并可以降低噪声4～5dB（A）。The suitability of rubber and fiber added to r micro -surfacing mixtures was examined in this paper on the basis of wet - wheel abrasion and load adhering sand tests. The results have shown that the asphalt content can be increased through adding rubber and. fiber, or stabilized agent from both composition; the abrasive resistance at micro -surfacing can be improved greatly by adding fiber to mixture; the content of rubber should not be larger than 5% to prevent deformation in the process of compacting . The composite stabilizer with 4% rubber and 0.02% fiber is the best for pavement performance of micro - surfacing with decreased of 4 -5dB noise of micro- surfacing pavement.
