泡沫沥青冷再生混合料配合比设计初探

摘要

针对沥青发泡效果、再生混合料设计、再生层施工工艺、工程应用等技术问题，通过理论分析、室内试验，分别研究了普通沥青发泡特性、泡沫沥青冷再生混合料物理力学性能、泡沫沥青冷再生混合料的配合比设计方法，为冷再生技术的应用推广提供了参考依据。%In light of asphalt foaming effect,recycling mixture design,recycling layer construction technology and engineering application and other technical problems,based on theoretical analysis and indoor experiment,the paper respectively studies the common asphalt foaming char-acteristics,physical mechanical performance of foamed asphalt cold-cycling mixture,and mixing proportion design method of foamed asphalt cold-recycling mixture,which has provided some guidance for promoting cold-recycling technology.
