摘要
文章对海南省花岗岩石料的黏结性开展了全面分析,经过沥青样品原材料试验和采用水浸法的集料黏附性试验,从XT-2液体抗剥落剂、SBS改性沥青、基质沥青、普通乳化沥青、改性乳化沥青、水泥和矿粉等施工材料的角度出发,详细分析了花岗岩沥青混合料和花岗岩黏附性的具体情况,并使用了冻融劈裂残留强度和浸水马歇尔残留稳定度改善其黏附性效果.
Abstract
The adhesion of granite stone materials in Hainan Province is comprehensively analyzed.Through the asphalt sample raw material test and the aggregate adhesion test by water immersion method,the adhesion of granite asphalt mixture and granite is analyzed in detail from the perspective of construction materials such as XT-2 liquid anti-stripping agent,SBS modified asphalt,matrix asphalt,ordinary emulsified asphalt,modified emulsified asphalt,cement and mineral powder,and the freeze-thaw splitting residual strength and immersion Marshall residual stability are used to improve its adhesion effect.
