不同纹理混凝土路面的抗滑与降噪性能研究

摘要

The anti-sliding characteristic and the noise law of the different texture features cement concrete pavement are studied through the pavement anti-sliding pendulum and the tire noise test.The results show that the british pendulum number are as from big to small,large diame-ter aggregate of exposed-aggregate cement concrete pavement (EACCP)>small particle size aggregate of EACCP>asphalt pavement>grooved road surface>ramming road surface.The near-tire noise values of different texture pavements are as follows grooved road surface>large diame-ter aggregate of EACCP>asphalt pavement>small particle size aggregate of EACCP.The noise value of the small particle size aggregate of EACCP is 1.8 dB lower than that of the grooved road,which is 1.0 dB lower than that of the asphalt pavement and it is the best noise reduction effect.%对不同纹理特征的混凝土路面,通过路面抗滑摆值和轮胎噪声测试,探究隧道水泥混凝土路面的抗滑特性和噪声规律.试验结果表明抗滑性能从大到小依次为:大粒径露石路面>小粒径露石路面>沥青路面>横向刻槽路面>拉毛路面.不同纹理路面的轮胎噪声值从大到小依次为:横向刻槽路面>大粒径露石路面>沥青路面>小粒径露石路面.小粒径露石混凝土路面的噪声值相对于刻槽路面降低了1.8 dB,较沥青路面降低了1.0 dB,抗滑与降噪效果最好.
