NOISE FROM CUT AND FILL OPERATIONS DURING ROAD CONSTRUCTION
Eight road construction sites were studied to measure and identify noise levels arising from earthmoving operations in cut and fill areas. Noise levels from typical plant undergoing normal working cycles were measured, and the energy equivalent continuous noise level (Leq) was used as the parameter which characterized the emitted noise over a working cycle. Measured values for several types of operation are tabulated. Observations led to a description of noise sources and parameters affecting noise propagation and generation for the followup situations: motorized scraper cuts and fills; loader and dump trucks and cuts; dump truck fills; and towed scraper cuts. About 50 percent of the 1-hour Leq noise levels at the site boundary were found to be greater than 75 dB(A). A smaller proportion of 12-hour Leq levels can be expected to exceed 75 dB(A) because of test breaks during the working day.
