Development of Green Paving Technology for Urban Roads

摘要

This The main objective of this study is to evaluate the feasibility of using Permeable Reclaimed Concrete (PRC) for urban roads construction. The PRC can be used at both stabilized base and wearing surface layers for new constructed pavements. The purposes of this paper were focused on the comparison of cost and energy consumption in both material production and pavement construction stages between PRC pavement and conventional hot-mixed asphalt (HMA) pavement. In addition, the potential ecological advantages such as reducing urban heat island effect as well as enrich groundwater table by using PRC pavement in the urban roads was also discussed. The results showed that the PRC pavement could effectively reduce 3 to 5°C surface temperature compare to conventional HMA pavement.
