Pavement performance evaluation method based on pavement use performance and material performance

Abstract

The invention discloses a pavement performance evaluation method based on the pavement use performance and material performance. The method comprises the following steps: detecting the pavement damage, a rut, a flatness value and a skid resistance performance; calculating a use performance index; carrying out coring on an evaluated pavement; collecting a uniaxial repeated direct tensile test and determining a fatigue parameter correction parameter; determining the number of rheological times by adopting a two-step secant method; determining apavement performance index, the rheological frequency and Marshall stabilityall evaluated road sections; constructing evaluation indexes of all evaluated road sections to form a matrix; constructing a standardized matrix and constructing an index maximum gray matter element; calculating an association degree matrix; calculating a determination matrix; calculating a maximum feature value according to the determination matrix and measuring the matrixconsistency by adopting a consistency index; determining an evaluation index weight matrix; determining the association degreesbetween all road sections and an optimal matter grey element; and evaluating the pavement performance of each road section according to the association degree between each road section and the optimal matter grey element. Therefore, the maintenance priority sequence of the road section can be determined and maintenance funds can be utilized reasonably.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a road performance evaluation method based on road performance and material performance. Background technique [0002] In recent years, due to the rapid growth of traffic volume, the service life of expressways in my country has been gradually extended, and most expressways have serious early-stage diseases, which have entered into intermediate repair or even overhaul projects ahead of time, which not only affects the normal operation of expressways, but also reduces the It not only reduces the benefits of transportation, but also reduces the service performance of the pavement, and has adverse effects such as an increase in the rate of traffic accidents. In order to ensure the quality of expressway maintenance, it is necessary to evaluate the pavement performance of expressways more reasonably and perfectly. At this stage, the road performance evaluation of expressway asphalt pav...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a road performance evaluation method based on pavement performance and material performance for the incomplete evaluation of highway asphalt pavement pavement performance in the prior art, so as to provide a basis for highway asphalt pavement maintenance in the future. The maintenance decision-making research provides a corresponding basis, and also provides a corresponding reference for pavement coring to detect the performance of asphalt pavement materials in service
