An Optimized Reinforced Concrete Pavement: Analitic and Numerical Performance Study

C. J. Martins, W. L. A. Pereira, L. A. Martins, R. A. F. Peixoto


This work reports the design of a particular pavement system composed by pre-casted reinforced concrete plates. This system, made by pre-stressed hollow-core plates, allowed the design of a durable, mobile and high-performance pavement system under heavy industrial loads. The structural and by geotechnical behavior of the plates, was performed both for numerical FEM tools and analytic solution (thin plate theory). The stress and displacement obtained by analyses allowed the design for the plates. By this way, the construction of a precast system for 652ton off-road trucks operation, located inside a very-dense industrial plant became possible in a very short time.
