This report details a study conducted using detailed roughness measurements on a panel of unsealed local roads located in Moorabool Shire Council at both the pre- and post-works effect (WE) treatment stages. The aim of the study was to develop interim WE models and validate any existing interim WE models, as well as validate current road deterioration (RD) models for roughness. Simple WE models were developed with the independent variable, IRIb, the roughness before treatment, which explained 59% to 91% of the dependent variable, IRIa, the roughness after treatment, depending on the type of works effect being modelled. No validation of any existing RD roughness model was possible due to the limited material and environmental variations.
