This report documents research undertaken to develop a methodology for refining existing road deterioration models for Australasian sealed granular pavements. A review of performance data obtained from accelerated load testing of sealed granular pavements was undertaken and documented. The data was used to derive relative performance factors and load damage exponents for increased wheel loadings. Relative performance factors and load damage exponents, in combination with performance data obtained from long term pavement performance sites and long term pavement performance maintenance sites, can be used to refine road deterioration models.
