Long-Term Field Performance of Pervious Concrete Pavement

Abstract

The work described in this paper provides an evaluation of an aged pervious concrete pavement in the Northeastern United States to provide a better understanding of the long-lasting effects of placement techniques as well as the long-term field performance of porous pavement, specifically in areas susceptible to freezing and thawing. Multiple samples were taken from the existing pavement and were examined in terms of porosity and unit weight, compressive and splitting tensile strength, and the depth and degree of clogging. It was concluded that improper placement and curing led to uneven pavement thickness, irregular pore distribution within the pervious concrete, and highly variable strength values across the site, as well as sealed surfaces that prevented infiltration.

Effects of coal fly ash and fine sawdust on the performance of pervious concrete

“…The core samples from in-place PC pavement gained an average compressive strength of 6.7 MPa. This lower compressive strength in the field compared to laboratory results indicates that the cores samples have been probably “overworked” during installation and inconsistencies occurred during placement and curing of the PC pavements (Radlińska et al., 2012). This result was also expected as larger aggregate sizes were used.…”

Clogging in permeable concrete: A review

“…Addressing this problem will substantially improve the durability of permeable concrete and optimise its application as a sustainable urban drainage system. Yet, this is not wellunderstood and limited information is available on factors influencing clogging (Tong, 2011;Mishra et al, 2013;Radlinska et al, 2012).…”

Holistic simulation of tire-pavement-system: Mechanics and uncertainty

“…Due to the presence of alkaline in pervious concrete, the pH of water is increased making it more neutral than acidic in nature. Studies show that in service pervious concrete removes 94.3% of phosphorous content in water (Radlinska et al 2012). The pervious concrete even reduced the heavy metals when the water was tested after infiltration.…”
