摘要
文章结合我国沥青路面施工技术规范的要求对泡沫沥青冷再生混合料进行配合比试验研究,以沥青膨胀率和半衰期为评价指标确定沥青最佳发泡条件和最佳拌和用水量,以间接抗拉强度(ITS)为控制指标确定最佳泡沫沥青用量,并通过对该泡沫沥青冷再生混合料的路用性能进行检测分析,验证了该配合比设计的合理性,为泡沫沥青冷再生混合料在实际工程中的推广运用和理论研究提供参考。
Combined with requirements of asphalt pavement construction technology specification in China,this article conducted the experimental studies on the mix ratio of foamed asphalt cold regenera-tion mixtures,the bitumen expansion rate and half-life period were used as the evaluation index to de-termine the optimal foaming conditions and best mixing water content of foamed asphalt,the indirect tensile strength(ITS)was used as the control indicator to determine the best dosage of bitumen froth,and through the test and analysis on the pavement performance of this foamed asphalt cold regenera-tion mixture,it verified the reasonableness of this mix design,thereby providing the reference for the promotional application and theoretical research of foamed asphalt cold regeneration mixtures in the actual projects.
