泡沫沥青冷再生基层研究进展

Research progress of cold regeneration base of foamed asphalt

为缓解地球资源紧缺、环境污染等问题,使冷再生技术更好地应用于道路工程中,本文综合整理了泡沫沥青、泡沫沥青冷再生混合料(CRMFA)的制备机理、性能影响因素与工程应用,从多方面介绍了目前泡沫沥青冷再生技术的研究进展。研究认为,目前CRMFA应用方面的研究仍有不足,后续研究应更好地同时兼顾配合比设计与工程实践,并建立基于不同环境、不同工况的CRMFA性能预测模型。

In order to alleviate the problems of resource shortage and environmental pollution and make the cold regeneration technology better applied in road engineering,the preparation mechanism,performance influencing factors and engineering application of foamed asphalt and foamed asphalt cold regeneration mixture(CRMFA)were comprehensively sorted out in this paperThe research progress of cold regeneration technology of foamed asphalt is introduced in many aspectsIt is pointed out that the current research on CRMFA application is still insufficientIt is proposed that the subsequent research should better take into account the mix design and engineering practice at the same time,and establish the CRMFA performance prediction model based on different environments and different working conditions.
