Abstract:

In this investigation a relationship between the ratio of the moduli of two layers in a two-layer pavement system and the ratio of deflections in a load deflected basin was developed. Charts correlating the relationship between these ratios are given in the report. By means of these charts, the moduli of the asphaltic concrete layers and the sublayer can be determined from dynaflect or Benkelman beam deflection data. A method of determining the moduli is outlined. This method can be used as an aid in correcting pavement deflections for changes in subgrade modulus values due to changes in subgrade moisture. The method is explained by means of examples.
