Pavement Noise 101: How Do Pavements Create Noise? How is it Measured? How Can It Be Controlled?

In an effort to reduce highway traffic noise, the four sub-sources of highway vehicles need to be addressed. These include: engine/drivetrain, exhaust, aerodynamic, and tire/pavement interaction. Tests show that surface texture with aggregate lengths greater than 20mm increases noise while lengths less than 10mm reduce noise. The porosity of the pavement and surface texture can also greatly affect the noise levels. To evaluate the effect of pavement noise reduction, a combination of statistical passby (SPB), controlled passby (CPB), and close provimity methods (CPX) need to be used. The methods to control highway noise are largely dependent upon the environment and the application, as there is no general guideline yet.
