Expert Commentary
Standard Test Method for Flexural Strength of Concrete (Using Simple Beam with Third-Point Loading). This is the Modulus of Rupture test for highway pavements. 4-point loading ensures a uniform moment in the center of the beam. MTO’s C78 fixtures feature free-rolling and tilting supports to eliminate frictional restraints, which can artificially inflate the recorded strength by up to 15%. This is a mandatory test for all DOT (Department of Transportation) projects.
