Road asphalt surface layer crack evaluation method based on nondestructive testing technology
The invention relates to a road surface layer evaluation index, in particular to a road asphalt surface layer crack evaluation method based on a nondestructive testing technology. The method comprises the following steps: determining the size of a detected road section, and establishing various crack sizes through detection: calculating to obtain an upper surface layer crack condition index, a middle surface layer crack condition index, a lower surface layer crack condition index and an asphalt surface layer overall crack condition index in the detected road section, and evaluating the indexes according to a road asphalt surface layer crack grading evaluation table. Based on a pavement nondestructive testing technology, the problem that existing evaluation indexes only evaluate the pavement form of open cracks is solved, the influence of all types of cracks of the pavement on the pavement service performance is comprehensively considered, the crack condition indexes of the upper surface layer, the middle surface layer and the lower surface layer are calculated respectively, and the overall crack condition index is calculated; the indexes are more representative, and the pertinence and scientificity of formulation of maintenance and repair measures are improved.
本发明涉及一种道路面层评价指标，尤其涉及一种基于无损检测技术的道路沥青面层裂缝评价方法。该步骤包括确定检测路段尺寸，通过检测建立各类裂缝尺寸：检测路段中通过计算得到上面层裂缝状况指数、中面层裂缝状况指数、下面层裂缝状况指数、沥青面层总体裂缝状况指数，依据道路沥青面层裂缝分级评价表对个指数进行评价。本发明基于路面无损检测技术，弥补了现有评价指标仅仅针对开口裂缝的路表形态进行评价的问题，综合考虑路面所有类型裂缝对路面服役性能的影响，对上面层、中面层、下面层分别计算裂缝状况指数，并且计算总体裂缝状况指数，这些指数更具有代表性，提升了养护修复措施制定的针对性与科学性。
