摘要
选取沪杭甬高速公路杭甬段K14+890-K33+148路段做为铺设天然岩(湖)沥青混凝土路面的试验路段,进行了天然岩(湖)沥青与改性沥青混合料的配合比设计及各项使用性能试验,试验表明:天然岩(湖)沥青混合料的高温稳定性与低温抗裂性增加、耐久性提高。经过近3a的通行验证,该试验路段未出现开裂、车辙、沉陷等病害,明显优于其它路段,可以推广使用。
Hangyong of K14 + 890 - K33 + 148 structural section of Huhangyong Freeway is used as experimental road which is paved by the natural rock (lake) asphalt concrete. The mixed proportion design of the natural rock (lake) and nature-changed asphalt mixture is made and various applications have been experimented. The tests show that the natural rock (lake) and nature-changed asphalt mixture is stable in high temperature and can resistcracking and aging-capacity has been improved. After nearly three years experimental, the trial road has not appeared broken sections, rutting, subsidence and other diseases, which much better than other sections The concerte can be widely used.
