沥青混凝土路面压实度的调查研究

Investigation on the Compactness of Asphalt Concrete Pavement

结合某高速公路的路面施工资料和路况的调查结果 ,分析了沥青混凝土路面的压实度与空隙率、空隙率与路面状况的关系。指出现行的路面压实控制方法不能真正有效地反映路面的压实状况 (路面实际的空隙率 ) ,由此提出了采用空隙率作为压实标准的推荐值。

The relationships between the compactness of asphalt concrete pavement and the ratio of void and between the ratio of void and PCI are discussed on the basis of the investigation on expressway. It is pointed out that the current compactness criterion is unable to reflect the real compactness status(i.e. the pavement ratio of void). And the proposed value using the ratio of void as compactness criterion is suggested .
