Publisher description for BAKFAA

BAKFAA program icon

BAKFAA performs backcalculation of pavement layer modulus values using the FAA layered elastic analysis program LEAF and a downhill multidimensional simplex minimization method. The function minimized is the sum of the squares of the differences between vertical pavement surface deflections measured with a falling weight deflectometer (FWD) and vertical pavement surface deflections computed with the layered elastic program.
