Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a dynamic division method for asphalt pavement maintenance road sections considering spatial continuity in view of the above-mentioned deficiencies in the prior art. The spatially continuous asphalt pavement maintenance road section dynamic division method can solve the problem that the existing fixed-length evaluation unit cannot make full use of the automatic detection data, resulting in the problem that the pavement condition evaluation unit is too long to cover up the poor pavement condition of some road sections or is not conducive to the organization of special maintenance construction

Abstract

The invention discloses an asphalt pavement maintenance road section dynamic division method considering spatial continuity. The method comprises the following steps: changing a fixed value of a pavement condition evaluation subitem index grade division critical value into a fuzzy intersection interval range; and on the basis, the road sections which are continuous in space and similar in disease severity are dynamically merged and divided, so that the problem that the road surface condition evaluation unit is too long to cover the local road section road surface condition is poor as the existing fixed-length evaluation unit cannot fully utilize automatic detection data is solved. And discrete distribution of same-zone maintenance road sections is not beneficial to special maintenance construction organization. By applying the method, the use condition of the highway pavement can be evaluated more accurately, a special maintenance scheme can be proposed in a targeted manner, construction organization is facilitated, and the use performance of the pavement is maintained.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a method for dynamically dividing an asphalt pavement maintenance road section considering spatial continuity. Background technique [0002] During the service process of asphalt pavement, the influencing factors of its technical status are relatively complex, including traffic load, external environmental factors and pavement structure, etc. The disease forms and maintenance methods of different road sections are also quite different. Therefore, when formulating an asphalt pavement maintenance plan, a reasonable division of maintenance sections is the basis for improving maintenance efficiency and effectiveness. my country's current "Highway Technical Condition Evaluation Standard" (JTG 5210-2018) (hereinafter referred to as the "Standard") stipulates that 1000m is used as the basic unit to evaluate the technical condition of asphalt pavement and analyze the maintenance...
