高速公路沥青路面车辙类型及检测技术

Rut Types and Detection Technology of Expressway Asphalt Pavement

以A、B 2条高速公路的沥青路面车辙病害为研究对象,按照车辙深度在1.0~1.5 cm、1.5 cm以上2个划分阶段依次选取典型断面,从而确定同一横断面的车辙特点,例如,波峰、波谷等。鉴于人工检测和自动检测2种方式在反映车辙类型和影响程度方面存在不全面的情况,遂引入切槽取芯的方法,以便更为准确地判断车辙类型以及具体的影响程度,从而加深对高速公路沥青路面车辙病害的认识,并进一步提出沥青路面设计及施工中应重视的技术要点,以供参考。

Taking the rutting of asphalt pavement of expressway A and B as the research object,according to the rut depth of 1.0~1.5 cm and above 1.5 cm,the typical sections were selected successively,so as to determine the rutting characteristics of the same cross-section,such as the peak and trough.In view of the fact that manual detection and automatic detection are not suitable in reflecting the rut type and influence degree,therefore,the grooving and core-taking method is introduced in order to judge the rut type and specific influence degree more accurately,to deepen the understanding of the highway asphalt pavement rutting disease,and further put forward the asphalt pavement design and construction should pay attention to the technical points,for reference.
