Model for pavement performance decay

Abstract

The invention discloses a model for pavement performance decay. The model comprises a central processing module, an electronic tag information collecting module, a cumulative equivalent axis number statistics module, and an electronic camera pavement condition statistics module. The central processing module includes a test vehicle information recording module, an information matching module and an information storage module. The cumulative equivalent axis number statistics module includes a vehicle weight collecting module, a vehicle speed collecting module, and a traffic volume statistics module. The pavement condition statistics module includes a pavement strength detecting module, a pavement damage degree detecting module, a pavement leveling detection module, a pavement anti-slip coefficient detection module, and a structure bearing capacity detection module. The model has the following advantages: the workload of the staff can be reduced; testing becomes convenient; the blindnessof the road section maintenance is reduced; the service life of the road is prolonged; and the calculated equivalent axis loading acting number can reflect the actual situation well.

Description

technical field [0001] The invention relates to the traffic field, in particular to a model of pavement performance decay. Background technique [0002] Pavement performance refers to the service ability of the road surface for driving under natural environmental conditions, including the surface structure characteristics, flatness, damage condition and structural bearing capacity of the road surface. The structure characteristics of the road surface affect the safety of driving. The friction coefficient between the road surfaces is evaluated, and the smoothness and damage of the road surface are directly related to the speed and comfort of driving, and are the main factors affecting the driving quality of the road surface. [0003] The structural bearing capacity determines the remaining life of the pavement, and is inherently related to the structural damage of the pavement. The lower the bearing capacity, the shorter the remaining life and the more serious the structural ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the pavement performance detection process is relatively complicated, and it is very inconvenient to go out for detection. It will also lead to a large error in the value of the coefficient when the equivalent axle load conversion formula is used. Only using the road surface performance as the basis for road maintenance will lead to the problem that the road will be damaged soon after maintenance.
