Fuzzy comprehensive evaluation and analysis on pavement performance of anti-condensation ice asphalt mixture
In order to evaluate the influence of self-made solid snow melting agent with sodium acetate,po-tassium acetate and sodium chloride as raw materials on the road performance of anti-condensation ice asphalt mixture with different mixing methods(internal mixing method and external mixing method)and different mixing ra-tios,the entropy weight method is used to determine the weight of each road performance index,and the fuzzy eval-uation matrix is established by using the theory of fuzzy mathematics.Finally,the fuzzy comprehensive evaluation of different anti-condensation ice asphalt mixture is carried out,so as to give the recommended mixing method and mixing ratio of self-made solid snow melting agent.The results show that the high temperature performance and water stability of the anti-freezing asphalt mixture will decrease when the self-made solid snow melting agent is mixed into the asphalt mixture in different proportions.The performance of anticoagulant ice asphalt mixture pre-pared by external mixing method is better than that of anticoagulant ice asphalt mixture prepared by internal mixing method.The pavement performance and anti-icing performance of 3.5%anti-icing asphalt mixture are the best.
