摘要
机场高速公路沥青路面基层采用注浆技术对脱空路段进行处治。采用探底雷达和冲击映像法检测评价了注浆处理路面内部脱空效果,结果表明,注浆材料能够显著提高基层密实度,基层强度有所提高,注浆处治具有较好的处治修复效果。
The asphalt pavement base course of Guangzhou Airport Expressway has been treated by grouting technology.Bottom-sounding radar and impact image method have been used to detect and evaluate the effect of grouting treatment on void in pavement.The results have shown that the grouting material could significantly improve compactness of the grass-roots,the strength of the grass-roots has been improved,and the grouting treatment has a good treatment and repair effect.
