| This study tries to compare the noise difference by various surface treatments and to propose appropriate tinning methods. As literature reviews, longitudinally tined pavement is effective to reduce noise made between tire and pavement surface. Various surface treatments were applied to some sections of test road. In case of car, about 2$sim$3dB(A) was reduced in the section of uniform space 18mm longitudinal tinning. The peak frequency point for truck case happened between 200 and 600 Hz. The maximum noise of car was measured at about 1000Hz. Therefore, it Is proved that surface treatment methods can have a large affect on noise generation. With a result that friction test, the transverse tined pavement showed better frictional characteristics than the longitudinally tined pavement, but as a whole it came out satisfactory result. Results from this study are of early age, so it is required to check the performance continuously. |
