农村公路路面碾压混凝土性能(阶段性)研究

Rural highway pavement performance of roller compacted concrete(periodic)research

公路路面碾压混凝土较常规普通混凝土具有抗压、抗折、抗冲击、抗疲劳等性能的优点。依托四川省苍溪县农村公路路面碾压混凝土科研项目,对路面碾压混凝土的基本性能进行研究,分析影响农村公路路面的碾压混凝土工作性的因素,原材料控制以及在此基础上提出了农村公路路面碾压混凝土的配合比例范围,同时,研究粉煤灰掺量对路面碾压混凝土的物理力学及耐久性能的影响。

Roller compacted concrete road pavement more routine normal concrete with compressive,flexural,impact resistance,fatigue resistance and so on significant performance advantages.It relied on Cangxi county ,Sichuan province rural highway pavement roller com-pacted concrete scientific research project,research on the basic performance of the pavement roller compacted concrete,analyzing factors that affect rural highway pavement roller compacted concrete workability,raw material control,and on this basis put forward rural high-way pavement roller compacted concrete mixing proportion range,on this basis,the research on the dosage of fly ash pavement influence of physical and mechanical properties of roller compacted concrete.
