| This study suggests a suitable random transverse tining for reduction tire/road noise from concrete pavement. Through literature reviews, random transverse tining that can disperse the energy concentrated to the specific frequency was suggested using the LCG(linear congruential generators) algorithm. The spacing of tining from this study is applied to Daegu-Pohang express highway. For the purpose oi comparison, two other random tining sections were included that are research products from Chung-Ang university and Wisconsin DOT. In result of pass-by noise measurement by car, though designed section is superior to the others as noise reduction by reducing pitch noise, the effectiveness is not large. In case of traffic noise measurement, lower noise was observed at random transverse tining sections than uniformly transverse tining section, too. But there are seine differences between pass-by noise and traffic noise. |
