Experimental Study on the Durability of Open Graded Friction Course Mixtures

Due to the high connected porosity, open-graded friction course (OGFC) is susceptible to water damage. And more, sunlight, air and water can enter into the interior of the course easily, accelerating the aging of asphalt and causing the durable problem. The aim of the paper was to evaluate the effects of mixture gradation and aging degree on the durability of OGFC mixture. Three gradations were selected, and then aged loosely in the oven for different hours. Then they were took out and fabricated into cylinder specimens. The Cantabro tests were conducted on these specimens to evaluate their durability. The results indicated that the gradation and aging degree have obviously effect on the durability.
