This report is an update of earlier Austroads sprayed seal design procedures based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when laying on its least…

Austroads has produced a series of test methods developed from various technical projects, principally in the bituminous materials area (asphalt, binders, slurry and sprayed seals). The Austroads system of managing the test methods has enabled…

An Austroads national workshop on sprayed sealing was held to assist development of a research program and identify challenges to the future use of seals. Delegates identified key issues under the themes of: safety and traffic management

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

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).…
