Construction and Performance of Poroelastic Road Surfaces Offering 10 dB of Noise Reduction
According to earlier research projects in Sweden and Japan, the poroelastic road surface (PERS), a pavement made of rubber granules and stone or sand aggregates, bound with a flexible polymer like polyurethane, is capable of reducing tyre/road noise by substantially more than any other type of surfacing. Earlier attempts to develop this concept into a low noise pavement ready for application in full scale and meeting reasonable requirements regarding safety and durability have failed. Reasons for the failures have been different in various experiments, but durability and/or safety have been the major problems. Never-theless, this project team had the idea that working together in a large European cooperation project and utilizing all kinds of pavement engineering specialists would be the way forward. In 2009, the European Commission accepted a proposal named PERSUADE (PoroElastic Road SUrface for Avoiding Damage to the Environment) to make a serious attempt to turn the concept and earlier practical experience into an implementable noise reducing product. The PERSUADE project has the intention to develop the PERS concept into a durable, highly noise reducing, safe and cost effective pavement which can provide exceptional traffic noise reduction under certain traffic and road conditions and thus provide European road and environmental authorities with a new tool for managing hotspots in noise exposed areas. The following pages summarizes the project work and results with focus on technical issues. Mix development The first step to achieve the goal is to develop an appropriate PERS mix formulation. The properties that had been defined as targets for the mix optimization included: •durability and stiffness of the material in the field •frictional properties during the service life and under various climatic conditions •noise absorption and noise generating properties in the interaction with tyres •drainage properties •rolling resistance •emissions of particulate matter and hazardous materials to the environment To ...
