Abstract
Tire noise is one of the primary sources of highway noise, particularly at high speeds. Different types of road surfaces generate different noise levels. Noise data were collected on eight different surface types found in Kentucky. Noise measurements were made using a reference car, and noise recordings were obtained from the traffic stream. A reference truck was used for one test. It was found that portland cement concrete; Class I, Type A and A(Modified) bituminous concrete; chip seals; and open-graded, plant-mix seals were more or less "normal" surfaces in regard to generated noise. Sand-asphalt and Kentucky rock asphalt surfaces were about 3 dBA quieter (cars) than "normal" surfaces. Grooved portland cement concrete surfaces were approximately 4 dBA louder (cars) than "normal" surfaces. The surface type did not affect the noise emitted by trucks.
