Abstract

To enhance the durability of semi-rigid base asphalt pavement, it is suggested that the asphalt treated base (ATB) layer should have certain drainage capacity to eliminate the water inside the pavement, and the crack resistance of ATB mixture should be improved to prevent and/or delay the generation and propagation of reflection crack. So, a kind of fiber reinforced open graded ATB mixture, FATB-25, was optimized. Then, the seepage, anti-rutting and anti-reflective crack capacity were measured, which were compared with those of AC -25 and ATB-25. The results indicated that the drainage capacity of the optimized FATB-25 meets the requirements, and its rutting resistance, anti-fatigue properties and anti-reflective crack capacity were significant better than those of the contrast mixtures, AC-25 and ATB-25.
