Description
Fly ash, a byproduct of circulating fluidized bed boilers (CF B), has good structural properties for a road surface but no known acoustical properties. Since high noise can cause psychological and physiological damage, traffic noise has become a major concern. Two types of measurements have been conducted. First, the traffic noise was measured using the statistical pass-by method on various road surfaces based on the ISO 11819-1 standards. Second, the sound absorption coefficients of the CF B materials from different boilers, asphalt, and concrete road surfaces were measured using impedance tubes. The CF B road surfaces produce lower noise in low speed range.
