A brief review of the environmental benefits and maintenance of porous concrete paving block

Abstract

Porous Concrete Paving Block (PCPB) is the most upper layer of permeable concrete block pavement in order to reduce stormwater runoff on the road pavement surface. The purpose of this work is to identify the impact of PCPB performance on the environment and maintenance required to ensure the pavement function optimally. This study assesses the main environmental advantages of PCPB in terms of reduced stormwater runoff, enhancing subsurface water quality and skid resistance, and minimizing traffic noise. Together with that, it contains PCPB performance, which is greatly impacted by mix design, installation method, service environment, and maintenance. Also, a brief discussion of the method for treating pavement pore blockage is included in this publication. Finally, new treatment technologies that can help increase PCPB performance in terms of water absorption are revealed for future research and innovation. This study aims to provide stakeholders and decision-makers with crucial information on managing stormwater and to promote the acceptance of PCPB as a demonstrable substitute for conventional pavement systems.
