摘要
介绍了泡沫沥青就地冷再生的原理及施工工艺,并在试验段施工,对试验段进行了压实度检测、马歇尔试验检测、弯沉测试。结果表明泡沫沥青就地冷再生混合料各项指标符合规范要求,弯沉代表值比改造前降低了37%左右,大大提高了路面的承载能力,且泡沫沥青就地冷再生利用技术能有效利用原有道路废弃材料,提高了经济效益和社会效益。
The principle and construction technology of foam asphalt on-site cold recycling were introduced. During the construction of test section,the compaction degree and deflection were tested and the Marshall test was conducted.The results show that all indices can satisfy the standard requirements;the deflection representative value decreases by about 37%,which greatly improves the capacity of the pavement,and the technology can effectively use the original road abandoned material to enhance economic benefits and social benefits.
