摘　　要：文章以中山翠亨新区榄横路复杂重载交通路段沥青混凝土路面病害为例,调查现有路面的病害,利用落锤式弯沉仪和3D三维探地雷达等先进检测手段,全面评估道路结构强度和内部病害情况;根据检测结果,结合实际工程经验,针对不同路段的病害程度,提出相应的处理方案;方案实施后,通过弯沉值、抗滑值、构造深度等路用性能指标进行检测,结果表明病害处理后的路面整体性好、承载力高、抗滑性能优,满足重载交通需求,能有效延长路面的使用寿命。Taking the asphalt concrete pavement disease in the road section with complex heavy-load traffi c on Lanheng Road in Cuiheng New Area of Zhongshan as an example,this paper investigates the existing pavement diseases,and uses advanced detection methods such as falling weight deflectometer and 3D three-dimensional ground penetrating radar to comprehensively evaluate the road structure strength and internal diseases.According to the test results,combined with the actual engineering experience,the corresponding treatment schemes are put forward according to the disease degree in different road sections.After the implementation of the scheme,the road performance indexes such as defl ection value,anti-skidding value and structural depth are tested.The results show that the pavement after disease treatment has good integrity,high bearing capacity and excellent anti-skidding performance,which meets the demand of heavy-load traffi c and can effectively prolong the service life of the pavement.
