Newly Paved Asphalt Rubber Road

A research project for establishing a novel methodology for systematically assessing and understanding the traffic noise of the Asphalt Rubber (AR) roads in comparison to the conventional asphalt roads, such that the traffic noise of the AR pavement can be reduced effectively with least cost. The Statistical Pass-By (SPB) method is also commonly known as the ISO 11819-1 traffic noise measurement method. The ISO 11819-1:1997(E) specifies the method of comparing traffic noise on different road surfaces for various compositions of road traffic for the purpose of evaluating different road surface and types. This measurement method is developed to measure the influence of the road surface characteristics to the emission and the propagation of road traffic noise as it is believed that these road characteristics notably the texture and the porosity can influence the propagation of sound especially the sound propagation close to the road pavement surface. This project is collaborated with Community of Tomorrow, Saskatchewan Highway and Transportation and Saskatchewan Scrap Tire Corporation.
