Test and Analysis on Asphalt Content for Fatigue Performance of Polyester Fiber Asphalt Concrete
Abstract:
The change law for fatigue properties of polyester fiber asphalt concrete was acquired under different asphalt content by three point bending tests. The results indicate that fatigue life of polyester fiber asphalt concrete increases firstly and then declines with asphalt content increasing, which shows an optimum asphalt content,4.8%. The optimal asphalt content of polyester fiber asphalt concrete is bigger than that of common asphalt concrete. The way to improve fatigue performance of asphalt pavement is found through studying on polyester fiber asphalt concrete. All will provide a theoretical basis for structural design of asphalt pavement.
