Effect Analysis of Different Ice-Melting Materials on Highway Pavement Based on Reduction Principles

We analyzed the influence of ice melting materials on pavement icing time and reducing adhesion force of ice to study the effect of different ice-melting materials on pavement and examined the effects of ice-melting materials at low doses. The results showed that the effect of reducing the freezing adhesion force was prominent under the condition of 5 g/m(2) lower spreading amount, and the freezing adhesion force was only about 1/10 of that obtained from the test without using industrial salt. Under the condition of small spreading amount, different ice melting materials could achieve better ice suppression effect. Under the condition of 5 g/m(2) low distribution, different ice melting materials had good effects in reducing the ice adhesion force, and the adhesion force obtained by using snow melting agent is only 7.18% of that obtained by the test without ice melting materials.
