High-viscosity and high-toughness asphalt pavement composite noise reduction agent, preparation method and use method
The invention belongs to the technical field of road and bridge materials, and relates to a high-viscosity tough asphalt pavement composite noise reduction agent, a preparation method and a use method thereof. The rubber powder is prepared from the following components in parts by weight: 40-70 parts of waste tire rubber powder; 10 to 30 parts of a toughening agent; 10-30 parts of a reinforcing agent; 0 to 15 parts of a tackifier; 0 to 10 parts of fiber; 5-10 parts of a filling agent; and 1-3 parts of other auxiliary agents. By preparing the high-viscosity tough asphalt pavement composite noise reduction agent, the utilization rate of the waste tire rubber powder is greatly increased, the waste tire rubber powder is used in an asphalt mixture, the elastic rubber particles are dispersed in the pavement, the pavement modulus is increased, and energy dissipation of impact vibration is achieved under the action of external force; compared with the prior art, the noise-reducing agent has good low-noise driving comfort, aging resistance and high and low temperature stability, a noise-reducing road surface prepared from the noise-reducing agent can reduce environmental noise by 4-5dB, special maintenance and cleaning measures are not needed, and the road surface has a lasting noise-reducing effect.
本发明属于路桥材料技术领域，涉及一种高粘韧沥青路面复合降噪剂、制备方法及其使用方法。由以下组份及其重量份配比制成：废轮胎橡胶粉40~70份；增韧剂10~30份；增强剂10~30份；增粘剂0~15份；纤维0~10份；填充剂5~10份；其他助剂1~3份。本发明通过制备高粘韧沥青路面复合降噪剂，大大提高了废轮胎橡胶粉的利用率，将其用于沥青混合料中，利用弹性橡胶颗粒在路面中分散，提高路面模量，在外力作用下实现冲击震动的能量耗散，与现有技术相比本申请具有良好的低噪音行车舒适性、耐老化性及高、低温稳定性能，由该降噪剂制备的降噪路面可降低环境噪声4dB~5dB，无需特殊维护清理措施，路面有着持久降噪功效。
