摘　　要：随着我国道路建设的快速发展,早期修建的普通国省道逐渐进入后服役期,路用性能逐渐降低,对路面面层的结构性修复需求日益增长,钢渣作为一种新型的固废利用材料,在道路工程中的应用日益广泛。本文以某普通国省道路网结构改造工程为应用实例,开展全钢渣微表处配合比设计,并以某实桥微表处桥面铺装进行试验验证,同步设置玄武岩钢渣微表处对比试验段,对比分析了钢渣微表处与玄武岩微表处桥面铺装的路用性能及经济效益,探讨了钢渣微表处桥面铺装的问题及改进措施。结果表明,钢渣微表处桥面铺装具有一定的抗滑耐磨性能,但后期存在钢渣飞散脱落及新铺桥面标线破碎现象,建议选用“粗钢渣细石料”的集料掺配策略;考虑阶梯运价及插值钢渣出厂单价后,全钢渣微表处较玄武岩微表处在折算单价上受运距、铺筑面积(或钢渣用量)的综合影响。With the rapid development of road construction in China,the ordinary national and provincial roads built in the early stage have gradually entered the post-service period,the road performance has gradually decreased,and the demand for structural repair of pavement surface has been increasing.As a new type of solid waste utilization material,steel slag is increasingly widely used in road engineering.In this paper,a common national and provincial road network structure reconstruction project is taken as an application example to carry out the mix ratio design of the whole steel slag micro-surfacing.The bridge deck pavement of a real bridge micro-surfacing is tested and verified.The basalt steel slag micro-surfacing contrast test section is set up simultaneously.The road performance and economic benefits of steel slag micro-surfacing and basalt micro-surfacing bridge deck pavement are compared and analyzed.The problems and improvement measures of steel slag micro-surfacing bridge deck pavement are discussed.The results show that the steel slag micro-surfacing bridge deck pavement has certain anti-skid and wear resistance.In the later stage,there is a phenomenon of steel slag scattering and falling off and the new bridge deck markings are broken.It is recommended to use the aggregate blending strategy of’coarse steel slag fine stone’.Considering the step freight rate and the interpolation of the factory unit price of steel slag,the whole steel slag micro-surfacing is affected by the combined effect of the transportation distance and the paving area(or the amount of steel slag)on the converted unit price compared with the basalt micro-surfacing.
