Abstract:
To determine the influence of material composition on the performance of color antiskid pavement materials, three kinds of color antiskid pavement materials with different material compositions were prepared considering the particle size, gradation, and amount of adhesives. Through rutting, surface structure depth, and antiskid pendulum tests, the hightemperature performance and antiskid performance of these pavement materials were compared and analyzed. Furthermore, their durabilities were studied systematically based on wear test under different environmental conditions and an accelerated loading test system, a wet wheel and four wheel abrasion instruments were used. The results show that the three kinds of color antiskid pavement materials have a suitable pavement performance, when the aggregate content of 4.75 to 2.36 mm is 100% and the adhesive spreading amount is 2.5 kg/m2, the dynamic stability and antiskid pendulum value of the color antiskid pavement material are the highest. These values are 8077 times/mm and 82 respectively. Meanwhile, the three kinds of color antiskid pavement materials were demonstrated to have a suitable durability, when the aggregate content of 4.75 to 2.36 mm is 100% and the adhesive spreading amount is 2.5 kg/m2, the wear value of the color antiskid pavement material is 70 g/m2 under the conditions of 1 h soaking, 64.7 g/m2 under a hightemperature condition, 105.88 g/m2 under a ultravioletaging condition, and under the condition of 10% HCL solution corrosion, the wear value is also 64.7 g/m2, after 50 000 wears, the wear mass loss is 43.3 g. The wear value and mass loss are less than those of other material compositions and all meet the normative requirements indicating the optimum durability of the color antiskid pavement material. 5 tabs, 9 figs, 31 refs.
