- Abstract:
-
In order to enhance the snow melting and ice removal performance of cold-mixed asphalt pavement in winter, the mechanical properties and anti-icing performance of the ultra-thin wear-resistant layer of cold-mixed asphalt were studied. It was proposed to replace 3-5 mm crushed stones with sustained-release anti-icing particles in equal volume to prepare anti-icing cold-mixed asphalt ultra-thin wear-resistant layer. And research was systematically carried out on its road performance evaluation and ice-melting rate prediction models. The test results showed that when the dosage (mass fraction, the same below) of anti-icing particles did not exceed 4%, the high-temperature stability, low-temperature crack resistance and water stability of the mixture all met the specification requirements. At a dosage of 2%, the dynamic stability reached the maximum value of 5 583.31 times/mm. The ice-melting rate had a nonlinear relationship with the dosage of anti-icing particles, and when the dosage was 3%, the ice-melting rate reached 23.4%, and the improvement was more significant at lower dosages, meeting the specification requirements. A prediction model for the ice-melting rate considering both dosage and temperature factors was constructed, and the goodness of fit R^2 was greater than 0.93. It could effectively guide the mix design of anti-icing materials for road surfaces.
