Seal Age Assessment - Quick, Simple, Portable

by Australian Road Research Board on August 11, 2020

ARRB has recently developed a new test method for the rapid, in-field, characterisation of binder ages in bituminous surfacings.

FTIR


ARRB has worked with local governments around the country to acquire seal samples for testing in our portable Fourier Transform Infrared Spectroscopy (FTIR) devices. This has allowed the device reading for the sample to be correlated to the functional age of the seal.

The research outcomes are presented in the project report, including the region-specific relationships for determining seal age from the FTIR output for participating areas.

Having an accurate understanding of the effective age of the seals on your road network can provide significant benefits for your maintenance programming.
