ENVIRONMENTAL NOISE IN AND AROUND HOT-MIX ASPHALT PLANTS

This brochure attempts to clarify much of the misunderstandings about noise problems in and around asphalt plants; it points out some of the problems and offers some general guidelines towards their most expedient and economical solutions. The noise theory (sound loudness, and sound power level) is explained, legal implications are discussed, and a sound test program and the use of certain charts to predict noise levels due to asphalt plant burner systems are outlined. Methods of controlling noise exposure and the procedure to follow are described. A plan of action is outlined which consists of the following steps: a walk-around survey of the plant; sound tests run by a noise consultant; preliminary discussion with a noise consultant; dBA survey of plant site; octave band analysis on all mobile and stationary equipment; isodyne map study to local high noise areas; consideration of the various methods of noise control; and the obtaining of ambient background noise measurements along property lines.
