Porous pavement : design and cost evaluation

Abstract

This study is a representation of the survey and experimental works carried out for the design of Porous Pavement as a Flexible Pavement. Porous Pavement is a new concept and does not find its application much in developing countries like India so the researchers are seeking opportunities to work on this new concept. Application of porous pavement will allow storm water to infiltrate into the ground thus reducing the problem of water accumulation in the areas. For this study, Siddharth Bungalows at Sama-Savli road of Vadodara has been selected for the Traffic Volume study and Road Inventory survey. The above residential road experiences a great threat of storm water accumulation during every monsoon. For this, rainfall data of different day, month is collected. Another important part is the traffic volume count which will help determining the low traffic volume load. The thickness of each component layers can be determined by collecting the soil of the location and determining its CBR value. The material selected is single sized aggregates of sizes 20mm, 10mm and 6mm and various laboratory tests are performed on these to determine their engineering properties. Here, Bitumen is replaced by low viscous and locally available material Tar.
