Application of Synthetic Fibre in Mixture of Asphalt Pavement

Article Preview

Abstract:

The fiber is a reinforced material which has relatively light texture, high strength, is durable and wear-resistant, and widely used in the mixture of asphalt pavement. Adding different types of fibers in the construction, has a good effect in preventing cracks in the road, the performance of the road will also enhance. After the appropriate amount of fiber added to the asphalt mixture, fiber molecules will continuously and uniformly spread out, this time it will increase the anti-destructive of mixture, and will play an important role in protecting the road, preventing the road fracture. Related practices abroad show that adding fiber in asphalt mixture, every performance of the mixture will increase in different degrees. The diameter and density of different types of fibers will be different, of course, the reinforcing effect are not the same. This article describes application of a synthetic fibre in asphalt mixture, which is polyacrylonitrile fiber.
