环境友好型减震降噪沥青路面技术研究

Study of Pro-environmental Shock Noise Reduction Asphalt Pavement

该文提出了橡胶粒应用于沥青混合料中的有关技术要求,针对粗橡胶粒SMA沥青混合料进行了室内的试验研究,并据此提出了具有良好路用性能的橡胶粒掺量。同时通过野外的噪声检测,验证了橡胶粒沥青路面具有良好的减震降噪效果。

The article puts forward the relative technical requirements of rubber particle applied in the asphalt mixture.In the view of the coarse rubber particle SMA asphalt mixture,the indoor ex- periment is carried out.And based on it,the admixture dosage,of rubber particle with the good rod use performance is put forward.At the same time to implement the outdoor noise detection,it veri- ties that the rubber particle asphalt pavement has the good shock noise reduction effect.
