Beam Bearing on Concrete. Last Revised 06/16/2011. A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. The action is essentially the same as a footing that distributes a large load to softer soil.

Sep 12, 2015 · Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
