摘要

After thin layer repaired, airport pavement will still appear crack, this situation not only spend a lot of maintenance costs, and seriously affect the use. This paper made flat constraint test for concrete containing poly carboxylic acid by using reinforced constraint plate mold, then the KON-FK(O) crack width tester and KON-FSY crack depth tester has been used in measuring on the surface of a block. Through the measured data analysis, crack effect is best when poly carboxylic acid with percentage of 2% and 2%.
