建筑废弃物应用于道路水稳层性能研究

Performance Research of Construction Waste Applied to Road Water Stability Layer

基于对罗湖棚改房屋拆除所产生建筑废弃物再生集料的性能试验,对其在道路水稳层的应用进行配合比试验,并通过实体工程路面基层、底基层试验段铺筑,掌握再生水稳混合料的加工、施工方法。房屋建筑废弃物再生集料的杂质含量和压碎值高于现行规范限值要求,但通过合理的配合比及生产过程控制,再生水稳底基层、基层的强度能够达到路用性能要求。

Based on the performance test of reclaimed aggregates of construction waste which generated from the demolition of Luohu sheds,the mix ratio test for the application of construction waste in the water-stabilized layer was conducted.Meanwhile,the processing and construction methods for the reclaimed water-stabilized layer were mastered through the trial pavement section of base and subbase layer.The impurity content and crushing value of recycled aggregates of building waste are higher than the current standard limit requirements,but the strength of base and subbase for the reclaimed water-stabilized layer can reach the performance requirement of road through reasonable mix design and production process control.
