Abstract
This paper reports the result of investigation into the effect of void percentage and water-cement ratio on aggregate fretting resistance of porous concrete pavement using ZKT-214:Method of Cantabro test for porous concrete. Test temperature is not specified in the ZKT-214 test method. On the other hand, test temperature in the Cantabro test for asphalt is specified as range in the B010 test method. The test is generally carried out at -20℃ in the case of low temperature. Thus, the effect of different test temperatures were investigated. No significant differences were observed in the Cantabro test for porous concrete pavement at different test temperatures. Aggregate fretting resistance was more affected by void percentage and the mortar-coarse aggregate void ratio(Km)than water-cement ratio. The porous concrete which had smaller void percentage or smaller the mortar-coarse aggregate void ratio(Km)had higher resistance to aggregate fretting. This result was especially related to the compressive strength.
