An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening). The binder hardening model was modified to include a seal size term. Data from early seal performance surveys in Victoria and W.A. were used as benchmarks and the new model was developed using data from a series of bitumen durability road trials placed in a number of regions of Australia and followed for up to 15 years. The new model permits reseal intervention point to be determined for seals of different nominal sizes in different climatic regions in Australia.
