A Functional Polymer Cement Mortar for Repair of Partially Damaged Asphalt Pavement

摘要

A newly polymer cement mortar to repair the rutting and bump of the pavement was developed and studied. In order to satisfy the required performance of the asphalt pavement as repair material, the polymer cement ratio of this mortar went up more than fifty percent. The basic properties such as workability, mechanical properties and adhesion durability of the polymer cement mortar was firstly investigated. Subsequently, the dynamic stability of the composite specimens repaired by the polymer cement mortar was clarified by wheel tracking tests. Finally, the availability of this mortar applied for the repair of the pavement was confirmed by the track running test more than two years.
