【摘要】 涂料型防滑表面处治系统是高等级道路路面防滑的一项新技术,其性能主要通过抗滑性和粘结性评价。通过摩擦系数试验和拉拔试验,研究该系统的抗滑性和粘结性,分析组成材料对摩擦系数和界面强度的影响。试验结果表明:摩擦系数主要受石料类型的影响,石英砂的摩擦系数最大。界面强度受基面类型和粘结料类型的影响,使用A粘结料时,水泥基面的界面强度高于沥青基面,使用B粘结料时,沥青基面的界面强度高于水泥基面;在沥青基面上,A粘结料的界面强度远小于B粘结料的界面强度,而水泥基面上使用2种粘结料的界面强度相当。更多还原

【Abstract】 Anti-skid surface dressing system with coating is a new technology in high grade road,whose performances are evaluated by anti-slip performance and cohesiveness.Though friction coefficient and pull-out tests,studying anti-slip performance and cohesiveness of this system,analysising the influences of friction coefficient and interfacial strength by component materials.The results suggest that: friction coefficient is mainly influenced by stone type;the friction coefficient of quartz sand is the biggest one.Interfacial strength are influenced by basal plane types and bonding types,when using bonding A,the interfacial strength of cement is higher than asphalt basal plane,when using bonding B,the interfacial strength of asphalt is higher than cement basal plane.The interfacial strength of bonding A is much smaller than B when they are used on asphalt basal plane,however,the interfacial strength of the two types are most the same when they are used on cement basal plane.更多还原
