泡沫沥青厂拌冷再生技术在国省干线公路上应用

Application of central plant cold recycling with foamed asphalt in provincial trunk highway

选用国省干线公路路面石灰粉煤灰碎石基层回收料进行泡沫沥青厂拌冷再生的研究,通过泡沫沥青冷再生室内试验,确定了最佳含水量、最大干密度以及最佳沥青用量,并结合试验路工程,阐述了厂拌冷再生的施工工艺及施工过程中应注意的事项。

This paper selected the lime fly ash macadam base recycling material of national provincial trunk highway pavement,researched the foamed asphalt cold in-plant recycling,through the foam asphalt cold recycling laboratory tests,determined the optimum water content,maximum dry density and optimum asphalt content,and combining with the test road engineering,elaborated the construction technology and matters should pay attention to in construction process of cold in-plant recycling.
