Chemical Freezing Check Pavement Application Summary

The disposal of snow cover converting into ice on pavement is a hard problem in winter for highway management departments. From the special material in asphalt materials, one chemi-cal freezing check pavement is put forward, which is economical and environmental-friendly. It can restrain pavement freezing to some extent and reduce the content of snow-melting agent, improve the efficiency of mechanical snow-removing, save highway maintenance cost in winter. It is significant to the development of snow-removing technology of economical and environmental-friendly pavement.
