A temperature correction method for pavement texture depth index based on equivalent temperature of asphalt surface layer

Abstract

The present invention relates to "a temperature correction method for pavement texture depth index based on the equivalent temperature of asphalt surface layer". The method takes the pavement texture depth index as the correction object and proposes a calculation method for the equivalent temperature of the asphalt surface layer to test the pavement structure within a time period. The average annual equivalent temperature of the asphalt surface layer is the standard temperature, and the equivalent temperature of the asphalt surface layer of the pavement structure at the time of testing is used as the reference temperature for correction, and the texture depth index of the asphalt pavement is corrected to the standard temperature. According to the temperature correction method of asphalt pavement texture depth of the present invention, the error of temperature correction can be reduced, the corrected pavement texture depth index is more in line with the actual road surface anti-skid performance state, and truly reflects the influence of four seasons temperature changes on the asphalt pavement texture depth index , realize the comparison of anti-skid performance of different asphalt pavement structures, guide the pavement structure to determine the best maintenance time, save the cost of pavement maintenance, and improve the safety of road driving.

Description

technical field [0001] The invention mainly relates to the field of road surface detection, and mainly relates to a temperature correction method of a road surface texture depth index based on the equivalent temperature of an asphalt surface layer. Background technique [0002] Pavement skid resistance is one of the main factors that determine the quality of asphalt pavement and driving safety, and is an important part of pavement service performance. The anti-skid performance of asphalt pavement is closely related to the surface morphology. The texture depth index of asphalt pavement is one of the important indicators affecting the anti-skid performance of the pavement. It is mainly determined by the micro-texture structure and macro-texture structure of the pavement. It mainly affects the skid resistance of asphalt pavement at low speed and dry conditions, and the macroscopic structure mainly affects the skid resistance of asphalt pavement at high speed or when the road su...
