Research on the Attenuation Law of Anti-skid Performance of Pavement in Different Maintenance Projects

Abstract

The lateral force coefficient is used both domestically and internationally to evaluate the anti-skid performance of asphalt pavement on highways. This article studies the attenuation law of anti-skid performance of different types of maintenance engineering easy to compact thin layer cover, micro surface treatment, in-situ thermal regeneration and semi open graded thin layer cover. The results indicate that the variation of SFC in different maintenance projects is directly influenced by the traffic level, and the larger the traffic level, the faster the attenuation of SFC. The ranking of the anti-skid and durability performance of maintenance projects under heavy traffic level is: easy compact thin layer cover, semi open graded ultra-thin cover>in situ geothermal regeneration, and micro surface treatment. The ranking of the anti-skid and durability performance of maintenance projects under the medium transportation level is: easy to compact thin layer cover>micro surface>inplace geothermal regeneration.
