Summary
In this paper rapid highway repair using reinforced precast concrete panels is investigated and a design method presented. In previous work, by one of the authors, using three dimensional finite element analysis and laboratory tests, a design method for the rapid repair of military runways was developed. Using this previous work, a design method was developed for reinforced precast concrete panels subjected to 80 kN standard axle loads. Using the client's requirements and details of the subgrade's strength and depth, the designer can then test and adjust the reinforced precast concrete panel's thickness, strength and steel reinforcement together with adjusting the subbase strength and thickness to satisfy the client's requirements. An example of how to use the design method is included in the paper.
