1、 Improve the stability of high temperature and improve the stability of high temperature Polyester fiber monofilament due to the three-dimensional distribution, and asphalt with a strong adsorption, and not winding, you can absorb too much free asphalt, the asphalt viscosity and viscosityThe cohesive force is increased and the flowability of the asphalt is reduced and the lateral displacement or flow of the aggregate is restrained due to the reinforcing and bridging effects of the criss-crossing. The stability of the fiber-asphalt concrete is effectively improved and the stability of the asphalt concrete is obtainedGreatly improved.
2、Improve the low-temperature crack resistance, fiber adsorption of asphalt, resulting in asphalt concrete, the best amount of asphalt increased, the higher the asphalt content, the fiber asphalt mixture at -40 ℃ low temperature remains flexible and high resistanceTensile strength, effective resistance to shrinkage stress, so that the mixture of low-temperature anti-cracking performance, reduce the production of thermal cracking and cracking can prevent the development of reflection.
3、Asphalt pavement in the external environment under the influence of the environment, subject to repeated wheel load, when the load after repeated more than a certain number of times, the load in the pavement under stress will exceed the strength of the structural resistance, so that The pavement Cracks, resulting in fatigue fracture damage, mixed with polyester fiber, the fiber monofilament in the mixture in the uniform distribution of the reinforcement, so that the stiffness modulus increases, to improve the asphalt concrete fatigue performance.
4、Improve water stability Asphalt pavement water stability is the asphalt pavement in the presence of water conditions, subject to traffic load and temperature expansion and contraction of the repeated role.The addition of polyester fiber makes the asphalt film thicken, reduces the strength of the water replacement asphalt, and reduces the amount of water infiltrated into the asphalt concrete, and the adsorption of the fiber increases the viscosity of the asphalt,And the ability of the interface membrane formed by the asphalt and the aggregates in the asphalt mixture to resist the water stripping action, thereby enhancing the water stability of the asphalt mixture.
