【摘要】 本文进行了以工业矿粉和工业醋酸合成有机环保道路融雪除冰剂的主要成分醋酸钙镁盐(CMA)的研究,并采用单因素优化和正交试验优化方法进行制备条件的优化,对制备的CMA复配得到3种不同的CMA型环保融雪除冰剂。以传统氯盐类融雪除冰剂作对照,借助沥青针入度、软化点、延度和红外光谱试验研究了3种不同的CMA型环保融雪除冰剂对沥青性能的影响;借助集料压碎值和集料与沥青黏附性试验研究了3种不同的CMA型环保融雪除冰剂对集料性能的影响;借助沥青混合料车辙试验、小梁弯曲试验、冻融劈裂试验和抗滑试验研究了3种不同的CMA型环保融雪除冰剂对沥青混合料路用性能的影响。通过现场融冰雪试验得出了有机环保型道路融雪除冰剂的撒布时机、撒布量和撒布频次等撒布工艺;进行了CMA型环保融雪除冰剂撒布后对周围土质和水质的影响研究;借助小麦种子和小叶黄杨进行了不同融雪除冰剂对植物的影响研究。综合研究结果表明:有机环保型道路融雪除冰剂具有良好的融冰雪效果;不同融雪除冰剂影响后沥青、集料和沥青混合料的性能均发生变化;三种CMA型环保融雪除冰剂撒布后对周围土质和水质影响极小;三种CMA型环保融雪除冰剂对植物的影响远小于传统氯盐类融雪除冰剂。更多还原

【Abstract】 In this paper,the research on the main components of industrial mineral powder and industrial acetic acid synthetic organic environmentally friendly road snow melting deicers,calcium acetate magnesium salt(CMA),and the optimization of the preparation conditions by single factor optimization and orthogonal test optimization method.Compounded the CMA to obtain 3 different CMA type environmentally friendly snow melting deicers.Taking the traditional chloride salt deicing agent as control,the effects of three different CMA environmentally friendly snow melting deicers on asphalt performance were studied by means of asphalt penetration,softening point,ductility and infrared spectroscopy.The effects of three different CMA environmentally friendly snow melting deicers on aggregate performance were studied by means of aggregate crushing value and aggregate and asphalt adhesion test.The effects of three different CMA environmentally friendly snow melting deicers on the pavement performance of asphalt mixture were studied by means of asphalt mixture rutting test,trabecular bending test,freeze-thaw split test and anti-slip test.Through the on-site melting ice and snow test,the spreading time,spreading amount and spreading frequency of the organic environmentally friendly road snow melting deicers were obtained.Research on the influence of CMA environmentally friendly snow melting deicers on the surrounding soil quality and water quality.The effects of different snow melting deicers on plants were studied with wheat seeds and lobular boxwood.The comprehensive research results showed that the organic environmentally friendly road snow melting deicers has a good melting snow performance;Theperformance of asphalt,aggregate and asphalt mixture were changed after different snow melting deicers affected;The three CMA environmentally friendly snow melting deicers have minimal impact on the surrounding soil quality and water quality;The three CMA environmentally friendly snow melting deicers have far less impact on plants than traditional chloride salt deicing agents.更多还原
