泡沫沥青再生混合料水稳定性的试验研究

Laboratorial study of moisture resistance performance for foamed asphalt recycling mixture

在室内试验的基础上,根据泡沫沥青再生混合料的物理特征和强度影响因素,探讨提高该材料水稳定性能的技术措施,包括拌和用水量、泡沫沥青用量、细料掺量、掺加活性填料和工后养护。随后通过国内外的工程经验总结对比,给出泡沫沥青再生混合料水稳定性能的评价指标和技术要求的建议值。

Based on physical character and strength effect factors of foamed asphalt recycling mixture, several technique methods, including proper mixing water content, foamed asphalt content, fine aggregate proportion, mixing active filling and maintenance after construction, are discussed by lab testing, which can improve its moisture resistance performance. Then the evaluating index and its re quiring value of moisture stability, of foamed asphalt recycling mixture are propounded on the basis of comparing construction experience both in and abroad.
