近年来,建筑与拆除废料在许多工程领域得到再生利用,公路与城市道路路面工程只需较少投入就能促进其大量应用,研究前景广阔。该文先简要综述已有相关室内外试验研究现状,着重介绍巴西2003年用再生集料铺筑基层、底基层的某沥青路面试验段,尤其是采用多种现场试验对该路面使用情况进行了8年多跟踪监测及分析评价。研究表明:再生集料能提供天然粒料相同水平的测试参数,类似于普通集料铺筑的路面,其性能可达到满意要求,建议在不同类型路面中更多地研究与应用。
In recent years, construction and removal of wastes have been reused in many engineering fields. Roads and urban road pavements can promote their large number of applications with less investment, so their research prospects are promising. In this paper, a brief review of the existing indoor and outdoor experimental research status quo, focusing on Brazil in 2003 with recycled aggregates paving grassroots, subbase a certain asphalt pavement test section, in particular the use of a variety of field tests on the road conditions More than 8 years tracking monitoring and evaluation. The results show that the recycled aggregates can provide the same level of test parameters of natural aggregates, which is similar to that of ordinary aggregates. The performance of the regenerated aggregates can meet the requirements. It is suggested that more research and application should be carried out on different types of pavements.
