• Abstract:
  This report is a sequel to a previous one that gave the details of a computer program capable of calculating in situ values of the Young's moduli of a pavement-subgrade (two-layer elastic) system from surface deflections measured at two points located at specified distances from the load wheels of a Dynaflect. The present report describes the effect of a change in the specified location of one of the deflected points on (a) the calculated moduli, (b) the shape of the deflection basin calculated from these moduli and (c) certain wheel load stresses calculated from the moduli at the pavement-subgrade interface. Dynaflect data from flexible highway pavements and rigid airport pavements are used in the calculations.
