摘要
水泥稳定碎石作为高等级公路半刚性基层结构其强度形成需要足够的时间,但是路面基层修建或修补时,有时为了加快施工进度并尽快开放交通,必须使基层的强度在短期内达到要求。采用自行研制的R-1型超早强修补剂对水泥稳定碎石材料进行改性,研究其路用性能。结果表明,掺入的R-1型超早强修补剂可使稳定碎石在16h内就能达到通车要求的性能。
Long time is required to form enough structural strength when aggregate mixture stabilized with cement that is used as semerigid base course of high class highway.In order to speed construction process and open to traffic early,it is necessary to form strength in short time for the mixture during construction or maintenance process.The properties of aggregate mixture stabilized with super rapid strengthening agent R1 that was made by autheres were studied.The results show that the R1 agent can make cement aggregate mixture come up to required features within 16 h.
