摘要
以河南省周口市泡沫沥青冷再生项目为例,通过泡沫沥青冷再生混合料配合比试验,提出了其配合比设计方法及步骤,具体包括:材料与级配设计、沥青及沥青发泡特性、拌和用水量的确定、试件的成型与养护、泡沫沥青最佳用量的控制指标以及确定方法等,并基于此,推荐了泡沫沥青冷再生混合料的设计原则及关键设计指标.
Taking the cold in-place recycling with foamed asphalt project in Zhoukou,Henan Province as an example,this paper put forward the mix design method and procedure for foamed asphalt cold recycled mixture through mixproportion experiment. The design contents includes material and grading design,asphalt and asphalt foamingcharacteristics,determination of mixing moisture content,forming and maintenance of specimens,control index anddetermination method for foamed asphalt optimal dosage. Based on the test results,this paper recommended thedesign principle and key specification for foamed asphalt cold recycled mixture.
