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.
