Study on Short Carbon Fiber Asphalt Concrete Marshall

摘要

The addition of chopped carbon fiber will effect on the pavement performance of asphalt concrete and reinforce and crack-resistance the concrete. The type, length and mixture of pitch carbon fiber have a significant impact on chopped carbon fiber asphalt concrete. This article discusses the effect of carbon fiber on the Marshall of concrete short asphalt, visits the change of Marshall Index, chooses the best short-cut ratio of concrete with carbon fiber asphalt and asphalt and gives guidance to the design of chopped carbon fiber asphalt concrete and construction.
