A STUDY INTO TOLERABLE DEFLECTIONS FOR PAVEMENTS: PROPOSED METHODOLOGY FOR INITIAL DATA COLLECTION
An Australian study has been set up to examine surface deflections which may be related to performance of various pavement types and hence provide a tolerable deflection criteria for the design of new pavements and the strengthening of existing pavements. The initial stages of the study involve the measurement of the surface deflections and condition on a limited number of unbound granular base pavements with bituminous surfaces in various locations in Australia. The data collected is to be used to develop an analytical procedure to produce deflection-use relationships. The report discusses the proposed methodology, and details the initial data collection procedure. In order to provide background to the study, information is given of the way pavement deflection is used in the current NAASRA pavement thickness design manual. The basic need is seen to be a relationship between surface deflection of a pavement and the number of standard axles that must pass over the pavement to produce a given surface condition (A).
