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

Abstract

The invention relates to a temperature correction method of a pavement texture depth index based on the asphalt surface layer equivalent temperature. According to the temperature correction method, the pavement texture depth index is used a correction object, an equivalent temperature calculation method of an asphalt surface layer is provided, the mean annual equivalent temperature of the pavementstructural asphalt surface layer within the test period is used as the standard temperature, the equivalent temperature of the pavement structural asphalt surface layer at the test moment is used asthe correction reference temperature, and the asphalt pavement texture depth index is corrected to the standard temperature. According to the temperature correction method of the asphalt pavement texture depth index, the error of temperature correction can be decreased, the corrected pavement texture depth index is more consistent with the actual pavement anti-skid performance state, influence ofseasonal temperature change on the asphalt pavement texture depth index is truly reflected, anti-skid performance of different asphalt pavement structures is compared, a pavement structure is guided to determine optimal maintenance opportunity, the pavement maintenance cost is saved, and pavement driving safety is improved.

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. However, the anti-skid performance of asphalt pavement is closely related to the surface morphology. Asphalt pavement texture depth is one of the important indicators affecting the anti-skid performance of the pavement. It 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 surface is wet. [0003] The pavement texture depth is an important manifestation of the current pavement surfac...
