徐州农村公路二灰碎石基层施工的试验和控制

Construction Test and Control of Lime Flyash-Macadam Base Course of Rural Road in Xuzhou

基于徐州市农村公路建设中的二灰碎石施工质量管理和控制,阐述了二灰碎石原材料选用、混合料组成设计及最大干密度控制标准,并结合施工过程中对二灰碎石混合料含水量、碎石级配、二灰与碎石比例等主要控制指标的试验检测进行了探讨分析.

Based on the working quality management and control of lime-flyash-macadam base course in rural road construction of Xuzhou,this paper gives explanations about the selection of raw materials,the design of mixture components and the control criteria for maximum dry density,and makes tentative studies according to the test detection of major control indexes in construction,such as the water content of line-flyash-macadam mixtures,the gradation of broken stones and the proportion of lime and flyash to broken stones.
