就地热再生技术在改性沥青GAC罩面层养护工程中的应用

Application of Hot In-place Recycling of Modified Asphalt GAC in Overlay Maintenance Project

文章结合改性沥青GAC罩面就地热再生的设计和施工过程,总结了其和常规就地热再生的区别,并以改性沥青GAC混合料和碎石封层为研究对象探讨了就地热再生设计与施工过程中需要注意的关键环节。文章建议为了保证碾压效果,必须控制再生机组的行进速度。

Combined with the design and construction of hot in-place recycling of GAC,this paper summarized the difference between hot in-place recycling of GAC and AC. Based on modified asphalt GAC mixture and chip seal,it discussed the key link of the design and construction of hot in-place recycling. It was suggested that the speed of regeneration unit should be controlled to ensure rolling effect.
