The article “Mechanistic-Empirical Design of Bituminous Roads: An Indian Perspective” (A. Das and B. Pandey, Journal of Transportation Engineering, 1999:463–471) presents an equation of the form y = a(1/x1)b(1/x2)c for predicting the number of repetitions for laboratory fatigue failure (y) in terms of the tensile strain at the bottom of the bituminous beam (x1) and the resilient modulus (x2). Transform this equation into a linear model, and express the linear model coefficients in terms of a, b, and c.
