    Abstract:

    In view of the phenomenon that the common pavement concrete is prone to crack upon its construction, analyses are made of the causes for such cracking, a new type of pavement concrete is developed by mixing the common concrete with fly ash and polypropylene fiber, and a test with plate specimen is adopted to fulfill the comparative test of crack - proof properties. The results of the test suggest that the common concrete, if mixed in proportion with either fly ash or polypropylene fiber, can improve its crack - proof property but the new-type concrete, mixed in proportion with both fly ash and polypropylene fiber at the same time, can more effectively prevent itself from cracking, thereby greatly prolonging the service life of the pavement.
