摘要
本文对浙江省04省道泡沫沥青厂拌冷再生应用项目进行了介绍,包括试验研究成果和工艺实践经验。试验研究中重点研究了铣刨速度对材料级配的影响,以及铣刨速度的确定方法,同时采用马歇尔指标和劈裂强度指标,对现场材料的力学性能进行了检测和评价;同时对现场材料的高温性能和抗压强度等指标进行了试验;工艺实践中,对拌和阶段和摊铺阶段有关施工需注意的事项进行了总结。
The application of the plant-mix cold recycling technology of foamed bitumen in No. 04 Provincial Highway of Zhejiang Province is introduced. These experiences include the test research results and the process control methods. The test research focuses on the influence of the milling velocity of milling machine on the gradation of materials and the methods how to determine the milling velocity. The mechanical performances of the site recycling materials are tested and evaluated through Marshall index and tensile strength index, and the indexes of the site materials such as high temperature property and compression strength are tested as well.
