3、lymer intensified, were analyzed. Test results show that the strength development of SCM-modified pervious concrete (SPC) differs from that of polymer-intensified pervious concrete (PPC), and porosity has little effect on their strength growth. PPC has higher flexural strength and remarkably higher

4、flexural-to-compressive strength ratio than SPC at the same porosity level. Results from fracture test of pervious concrete mixes with porosity around 19.5% show that the fracture energy increases with increasing the dosage of polymer, reflecting the ductile damage features rather than brittleness. PPC displays far longer fatigue life than SPC for any given failure probability and at any stress level. It is proved that two-parameter Weibull probability function describes the flexural fatigu
