Development of a durability test method for sprayed sealing binders: a field validation study

This report presents the results of a field validation study that was conducted as part of the development of a new long-term ageing (durability) test for bituminous binders used in sprayed seals in Australia. The field validation study of the new durability test method was conducted using field property information collected from a sprayed sealing trial site constructed at Coober Pedy in South Australia. Analysis of the results from dynamic shear rheometer (DSR) flow tests and Fourier transform infrared spectroscopy (FTIR) tests found a reasonable similarity between the ageing process simulated using the pressure ageing vessel (PAV) for a short time (e.g. 30 hours) and the ageing process which occurred in the field for a certain service period (e.g. 3 years). The validation study suggested that PAV treatment is able to produce artificially aged binders which are quite similar to field aged binders that have been in service for a long time. Due to this, PAV treatment of binders appears to be a suitable approach for ageing binders in the new durability test method.
