Preparation and Evaluation of Durability of Color Antiskid Pavement Particles Subjected to Different Treatments

Abstract

To improve the durability of color antiskid pavement and the abrasion resistance of its antiskid particles, an organic treatment agent (OTA) is selected to treat the antiskid particles. The before-and-after study of the OTA treatment on the properties of the antiskid particles is conducted. The abrasion resistance of color antiskid pavement is discussed by using four evaluation indexes: abrasion mass loss rate, British pendulum number attenuation rate, texture depth attenuation rate, and bond strength. In addition, the color durability of color antiskid pavement under single and complex conditions is studied by using the color brightness coefficient as the evaluation index. Compared with untreated antiskid particles, the OTA demonstrates a 54%, 29%, 44%, and 34% reduction in water absorption, weared stone value, crushed stone value, and mass abrasion shedding rate, respectively, on the treated particles. Furthermore, the OTA produces a 5%, 16.7%, and 9.7% decrease in abrasion mass loss rate, British pendulum number attenuation rate, and texture depth attenuation rate, respectively, whereas it produces a 33.3% increase in bond strength, compared with untreated specimens. Moreover, under four conditions: liquid corrosion, ultraviolet radiation, combined high-temperature and liquid corrosion, and combined high-temperature and ultraviolet radiation, the maximum reduction of the color brightness coefficient of color antiskid pavement with OTA treatment is 85.8%.
