Abstract
The number and severity of the damaged yard crane passageways on the wharfs are increasing year by year. Based on the research results of thin-layer repairing of the damaged passageways of yard cranes at home and abroad in recent years, this paper analyzes the characteristics and hazards of thin-layer disease of concrete pavement and measures the mechanical properties and durability of thin-layer rapid repair materials through setting time test, mechanical test, abrasion resistance test and frictional coefficient test. It is concluded that its properties can meet the requirements of thin-layer repairing technology, and some engineering examples of thin-layer rapid repair are listed in this paper.
