Elastic Modulus Pavement Interactive
Elastic Modulus. Thus, the modulus of elasticity is the slope of this part of the curve and is equal to about 207,000 MPa (30,000,000 psi) for steel. It is important to remember that a measure of a material's modulus of elasticity is not a measure of strength. Strength is the stress needed to break or rupture a material (as illustrated in Figure 1),...
