---

The deiceing asphalt pavement is used to ensure traffic safety in winter. But ,in recent year, the rapid decrease of the deicing capacity of a certain number of deicing pavements, as well as the short lasting deicing properties were met with skepticism. So, we suggested the deicing asphalt mixture design method and evaluation methods last year. In the present study, we report the result of the study of lasting deicing properties in deicing asphalt mixture designed the suggested desing method.
