Thickness Optimization of Portland Concrete(PC) Pavement with Lean Concrete Base 采用贫混凝土基层的水泥混凝土路面厚度优化
The physical and mechanical properties and durability properties of the geopolymer blend cement ( GBC ) concrete and the ordinary Portland concrete ( OPC ) are compared in laboratory experiments. 用正交试验确定合成地聚物水泥的最优配方,以单因素试验说明改变沸石的质量分数和粒度对地聚物水泥机械性能的影响。
Influence of load stress and deflection on interfacial interaction between portland concrete pavement and lean concrete base 混凝土面层与贫混凝土基层的层间作用对荷载应力和弯沉的影响
Different thickness combinations of lean concrete base and portland concrete pavement will greatly influence load stress in pavement. Based on all kinds of requests in real pavement, a mathematic model of thickness optimizing is put forward. 贫混凝土基层与水泥混凝土面层的不同厚度组合会对路面荷载应力产生较大的影响,考虑实际路面的各种要求,提出了厚度优化的数学模型。
Double-layer Reinforced Concrete Pavement is one of jointed Portland Concrete(PC) Pavement sturctures with two double layer steel bars in the longitudinal direction in order to prevent the possible spread of cracks on the surface. 双层钢筋混凝土路面是在面层板内配置上下两层纵向和横向钢筋,以防止可能产生的裂缝缝隙张开的一种设接缝混凝土路面结构。
