The authors of this paper studied the dependence of resilient modulus of cement-stabilized phosphogypsum on various material parameters. Specifically, the dependence of the resilient modulus on cement content, dry unit weight, moisture content, and curing time was determined. Investigators learned that the resilient modulus increases with increasing density, cement content, and time of curing before testing, but decreases with increasing moisture content. Relationships between resilient modulus and the parameters were estimated and a multiple correlation between the resilient modulus and the four parameters was derived. Such relationships could aid in the design of pavements, the estimation of pavement life-cycle performance and cost, the determination of layer coefficients, and the assessment of stabilized phosphogypsum pavement materials in terms of stress or strain behavior.
