摘要
多孔性沥青混合料虽有较好的降噪效果,但路面耐久性略显不足,针对密实型级配在沥青路面中具有较好的路用性能特点,通过室内试验和现场监测对密实型橡胶降噪沥青材料的降噪特性进行了研究。在室内外试验中,密实型沥青材料降噪效果约5.5 d B,比普通沥青路面材料提高了1.5倍;且密实型降噪沥青路面的路用性能也能较好满足设计要求。
The mgradation in asphalt pavement has a good road performance, a study is made to test the noise reduction characteristics of compacting type noise reduction rubber asphalt through the indoor test and field monitoring.Tests show taht the denseness asphalt material noise reduction is about 5.5 d B, increased by 1.5 times compared to ordinary asphalt pavement material; moreover, the pavement performance of compacting type noise reduction asphalt can also satisfy the design requirements.
