    摘要:

    密级配橡胶沥青路面是低噪声路面发展的新形式。为了推动低噪声路面的发展,阐述了轮胎/路面噪声的产生、增强机理及密级配橡胶沥青路面的降噪机理和降噪效果。首先介绍大孔隙和密级配两种类型降噪沥青路面及其降噪机理,然后对轮胎/路面噪声的产生和增强机制进行论述,接着针对密级配降噪沥青路面降噪模式、胎路噪声的影响因素及检测方法进行重点评述,最后对密级配低噪声沥青路面的发展及优化方向进行展望。大多数低噪声沥青路面都偏向于开级配大孔隙类型,对密级配沥青路面的降噪机理及实现路径研究较少。开级配大孔隙沥青路面在孔隙堵塞时,其降噪效果急剧下降,并且堵塞的孔隙难以恢复,这制约了其广泛使用。而密级配橡胶沥青路面通常依靠自身丰富的表面纹理及橡胶颗粒的弹性实现吸声阻尼降噪,故不存在上述不足。密级配橡胶沥青路面虽在降噪效果方面不如开级配大孔隙路面,但因其优异的路用性能和持久稳定的降噪效果,已成为低噪声路面在实际工程应用中的重要选择。为了更好应用密级配橡胶降噪沥青路面,未来应重点研究影响其降噪效果的诸多重要因素,如橡胶颗粒的掺入方式、粒径和掺量等。

    Abstract:

    Dense-graded rubber asphalt pavements are the new forms developed from low-noise pavements. In order to promote the development of low-noise pavements, the generation and the enhancement mechanisms of tyre/pavement noise were described, as well as the noise reduction mechanism and the effect of dense-graded rubber asphalt pavements. Firstly, two types of noise reduction asphalt pavements with large porosity and dense gradation and their noise reduction mechanisms were introduced. The generation and the enhancement mechanisms of tyre/pavement noise were discussed. Secondly, the noise reduction mode, influencing factors of tyre/pavement noise, and detection methods of dense-graded asphalt pavements were emphatically reviewed. Finally, the development and the optimization directions of dense-graded low-noise asphalt pavements were prospected. Most of the low-noise asphalt pavements are open-graded ones with large porosity,while there are less researches on noise reduction mechanism and the realization path of dense-graded asphalt pavements. When the pores are blocked, the noise reduction effect decreases sharply and the blocked pores are difficult to recover, which restrict the wide application of open-graded asphalt pavements with large porosity. In contrast, the dense-graded rubber asphalt pavements usually rely on their own rich surface textures and the elasticity of rubber particles, so as to achieve sound absorption damping and noise reduction, avoiding the above shortcomings. Although the noise reduction effect of dense-graded rubber asphalt pavements is not as good as that of open-graded pavements with large porosity, dense-graded rubber asphalt pavements have excellent road performances and long-lasting noise reduction effects, thus becoming an important choice for low-noise pavements in practical engineering applications. In order to better use dense-graded rubber asphalt pavements with noise reduction effects, future researches should focus on various important factors affecting the noise reduction factors of the pavements, such as the incorporation of rubber particles, particle size, content and so on.
