- Problem 32: What is the stiffness factor of a pavement if the modulus of elasticity is 180 MPa and whose subgrade modulus is 40 MPa?Design a pavement for a rural interstate highway. The expected design ESAL is 13x106. The pavement structure is to consist of asphalt concrete with an elastic modulus of 400000psi, a granular base with an elastic modulus of 26000psi, and a granular subbase with an elastic modulus of 12000psi. The elastic modulus of the subgrade is 8000psi. It is estimated that it will take a week for water to drain from the pavement and that the pavement will be saturated about 15% of the time. Assume that a reliability level o about 90% is required and that the initial serviceability index is 4.2 and the final serviceability index is 2.5.If pavement and sub grade are considered as two layer system a stiff factor is to be introduced to take into account the different values of modulus of elasticity of the two layers. if the modulus of elasticity of the subgrade is 100 kg/cm2 and the modulus of elasticity of the pavement is 1000kg/cm2, what is the stiffness factor ?
