沥青路面施工均匀性精细化检测方法
|
摘要
为有效评价沥青路面的施工均匀性,该文研究了沥青路面施工均匀性检测方法。通过室内试验并依托铜旬高速实体工程,分析了各种沥青路面非均匀性检测方法的特点,提出沥青路面施工均匀性精细化检测方法,并进行了实例验证。结果表明,直接检测法无法表征路面内部集料颗粒及空隙在空间分布上的差异,且随机选点的取芯方式使检测结果不能全面反映沥青路面的施工均匀性;间接检测法也无法反映路面结构内部的施工均匀性。从压实均匀性和集料分布均匀性出发,该文基于现场和芯样的非均匀性精细化检测方法可有效评价沥青路面的施工质量。
To evaluate the construction uniformity of asphalt pavement effectively,the study on the construction uniformity of asphalt pavement is carried out. The characteristics of different detection methods of heterogeneity for asphalt pavement are analyzed by indoor experiments and the Tong-Xun pavement engineering. According to the deficiency of construction uniformity detection for asphalt pavement,the method of accurate construction uniformity detection for asphalt pavement is put forward and verified by examples. The results show that the direct detection method can not characterize the spatial distribution difference of aggregate particles and voids inside the pavement. And the random selection way for core samples makes the test results can not fully reflect the construction uniformity of asphalt pavement,and the indirect detection method can not reflect the construction uniformity of internal structure for asphalt pavement. Based on the characteristics of different uniformity detection methods,the detection method of accurate heterogeneity combing the compaction uniformity and the aggregate distribution uniformity can be used to evaluate the construction quality of asphalt pavement effectively.
