Pavement

A new Pavement Work Tip on sprayed sealing aftercare, together with four updated resources covering nozzle selection, binder sampling, dust suppression and binder cutting practices, provides road agencies and contractors with practical guidance to improve pavement quality, reduce defects and support longer-lasting sprayed sealing outcomes.

Road agencies can now make more informed decisions about bitumen selection to reduce premature cracking and extend the life of sprayed seals, supported by a new Austroads test method for assessing the long-term performance of aged bitumen.
