Load Carrying Capacity of Minnesota Secondary Flexible Pavements
The load carrying capacities of highways in Minnesota have been evaluated by a plate bearing test procedure for 16 years. Many counties and municipalities are interested in strength information on their roads and streets to establish spring load restrictions and to evaluate their design strengths. However, the plate bearing test requires a special trailer, the total cost of which is such that it is not feasible for most counties to acquire it. The purpose of this investigation is to study the Benkelman Beam test, another method of evaluating road strength, and to relate the results obtained to those of the plate bearing test. Field measurements were made over a period of 7 years. Basically the data consist of plate bearing test results and Benkelman Beam deflection measurements, along with information on the pavement structures and subgrade soils. The Benkelman Beam deflections are used to evaluate the pavement strengths in two ways. One way correlates the deflections and the plate bearing values and obtains the allowable tonnage capacity of the pavement through previously established tonnage-plate bearing value relationships. Another method establishes the allowable spring tonnage directly with the Benkelman Beam deflection test. (BPR Abstract)
