Review of porous concrete as multifunctional and sustainable pavement

Abstract

Porous Concrete (PC) pavements have been gaining a lot of attention in recent years because of the many ad-vantages they can provide, especially in urban areas because they are capable of mitigating the water and air environmental impacts caused by conventional roads, as well as to increase driver safety. Nevertheless, according to the present research results, their use is still limited, since there are not enough studies addressing them comprehensively, mainly because of the lack of awareness about all their potential benefits. Therefore, this paper reviews the main properties that PC mixtures can provide for designing multifunctional and sustainable pave-ments. To this end, the investigations undertaken during the last decade (2009?2018) in this topic were analyzed in detail, identifying the regions where they are being most widely studied, analyzing and predicting their future potential developments. 171 publications in the topic were found in Scopus database, where mechanical and hydraulic capacity are the two main properties studied in PC pavements, with 36% and 41%, respectively. In addition, a predicted growth for 2019?2030 of 2.51% (4.29 PC publications per year) is expected.
