Construction of pervious concrete pavement stretch, Ahmedabad, India – Case study

Rapidly growing and uncontrolled changes in the natural landscape due to human intervention has created a serious problem of rainwater harvesting in many Indian cities. Rainwater is seen getting wasted on the roads due to lack of proper design of drainage system. Construction of Pervious concrete pavement (PCP) is one of the best method to solve this problem. The pervious nature of the pavement is suggested to act as a drainage pipe and the water accumulated on the road or pavements drains out immediately. Therefore, an attempt has been made for the construction of PCP in this present study. The PCP was constructed at Nirma University campus, Ahmedabad, India for study purpose. The size of PCP stretch was 3 m × 10 m. The details of construction methodology and material used for the construction of PCP are included in this paper. In addition to that, properties of pervious concrete (PC) such as void ratio, compressive strength, permeability and density were evaluated and compared with field investigation results. The 28 days results of PC field cores and cast specimens achieved similar range for compressive strength and void ratio. Moreover, maintenance schedule was prepared for the supervision of PCP. The infiltration rate was measured at different intervals to determine if there was clogging in the PCP. Based on the results of this investigation, it is seen that there is successful drainage performance of the PCP, demonstrating the possibility of construction of such pavements in the water logged areas of India.
