本文提出了刚性路面填缝料的基本特性;对封填混凝土路面和机场道面接缝的沥青橡胶、聚氯乙烯胶泥、聚氨酯焦油填缝料和新研制的ZJ型、聚氨酯整皮微孔泡沫塑料填缝料的技术性质进行了室内鉴定及路用性能的对比分析;研究了聚氯乙烯类填缝料的技术标准;拟定了刚性路面填缝料的试验方法。本文研究成果于1984年7月通过部级鉴定,并指出“五种填缝料,各地可视具体情况选用;刚性路面填缝料试验方法是可行的;聚氯乙烯类填缝的技术标准较为适合,建议列入施工规范”。
In this paper, the basic characteristics of rigid pavement sealant are put forward. Asphalt rubber, polyvinyl chloride cement and polyurethane tar sealant for sealing concrete pavement and airport pavement joint and newly developed ZJ-type, Plastic caulk technical properties of the indoor identification and comparative analysis of road performance; study of PVC sealant technical standards; developed a rigid pavement test methods. The research results of this paper passed ministerial appraisal in July, 1984 and pointed out that “five types of sealant can be selected in different places depending on the specific conditions; the test method of rigid pavement sealant is feasible; the technical standard of PVC sealant is relatively Suitable, proposed inclusion in the construction norms. ”
