A Research Paper on Porous Asphalt Pavement

Abstract

The aim of this study is to recharge ground water to underplaying aquifers and reduce risk of flood condition. Porous asphalt pavement is an alternative technology that differs from traditional asphalt pavement designs, that the pavement permits fluid to pass freely through it. Porous asphalt pavement also reduces and control surface runoff of surrounding area. This technique also can be used as additional way of storm water management. The past few studies suggests that, porous asphalt pavement intended to be used for parking lots, storm water management, water quality treatment, peak flow reduction and noise control. The research has focused on improving quality and quantity of ground water. This study includes model making and checking performance of that constructed pavement model. Study investigates performance of aggregates and porous asphalt used in projects, such as properties of aggregates like impact value, crushing value, specific gravity, abrasion test. Tests performance on porous asphalt includes ductility test, stripping value test and penetration test. Study includes sample making of various proportion of asphalt and aggregates. Total 9 samples were made to check which sample gives best performance as per the requirement. Out of 9 samples, 6% asphalt with 10mm aggregate + grit sample gives required performance.
