Durability of Certain Configurations for Providing Skid Resistance on Concrete Pavements.

摘要

The main objective of the study was to establish the factors that influence the durability of the surface configurations that are used or can be used to provide high and long lasting skid resistance for portland cement concrete pavements. In the development of such durable surface texture an insight into pavement wear mechanism in the presence of grooves is necessary. The wear of pavements may involve polishing and small scale degradation at the top surface as well as a possible large scale material loss in concrete. The wear phenomena occurring at the top surface was investigated experimentally by petrographic examination of thin sections prepared from the cores taken from actual highways undergoing various degrees of wear. The structural behavior of the area below the top surface and around the grooves was investigated theoretically.
