Software for Load Distribution on Low-Fill Box Culverts: User’s Manual, Technical Summary
The American Association of State Highway and Transportation Officials (AASHTO) provides three methods of load rating: 1. Allowable Stress Rating (ASR); 2. Load Factor Rating (LFR); and 3. Load and Resistance Factor Rating (LRFR). The Load Factor Design (LFD) method and the Load and Resistance Factor Design (LRFD) method have been mostly used by Departments of Transportation (DOTs) to load rate the buried culverts. The LFD method considers the wheel load acting as a point load on fill, which is distributed onto a square area on the culvert with a width of 1.75 times the fill depth above the culvert. The LRFD method suggests the wheel load be applied on a rectangular area as a tire footprint and distributed onto the culvert by increasing the tire footprint by 1.15 times the fill depth.
