Abstract EN
Fiber, as an additive, can improve the performance of asphalt concrete and be widely studied, but only a few works have been done for hybrid fiber.
This paper presents a new and convenient method to design hybrid fiber and verifies hybrid fiber’s superiority in asphalt pavement engineering.
Firstly, this paper expounds the design method used as its applied example with the hybrid fiber composed of lignin, polyester, and polypropylene fibers.
In this method, a direct shear device (DSD) is used to measure the shear damage energy density (SDED) of hybrid fiber modified asphalts, and range and variance statistical analysis are applied to determine the composition proportion of hybrid fiber.
Then, the engineering property of hybrid fiber reinforced asphalt concrete (AC-13) is investigated.
Finally, a cost-benefit model is developed to analyze the advantage of hybrid fiber compared to single fibers.
The results show that the design method employed in this paper can offer a beneficial reference.
A combination of 1.8% of lignin fiber and 2.4% of polyester fiber plus 3.0% polypropylene fiber presented the best reinforcement of the hybrid fiber.
The cost-benefit model verifies that the hybrid fiber can bring about comprehensive pavement performance and good economy.
