Viscoelastic Properties Research of Sisal Fibre Asphalt Concrete

Asphalt concrete is a typical complex of viscous, elastic and plastic.So the raw materials should be fully considered, such as asphalt, aggregate, filler, etc, when research to viscoelastic. Viscoelastic can influence various properties, even to service life of the road and its performance. Therefore, if can improve the viscoelastic properties, it will have a lot of influence to asphalt concrete. Through to add 0.2% sisal fibre to common concrete to study the viscoelastic properties, this article seek to improve the viscoelastic method, in order to play the role of asphalt concrete better.
