Spray Seal Construction and Failure Review
Reduce the risk of failures, maximise your value for money and minimise liability by selecting and designing a sprayed seal which will suit the traffic, pavement and environmental conditions using a rational, reliable, proven approach.
This course focuses on when and where sprayed treatments can be used by introducing participants to the strengths and weaknesses of the various types of sprayed treatments commonly used including the types of surface defects that may be corrected.
Instruction is provided on the use of the current Austroads seal design method for priming, primersealing and sealing, using real world examples and interactive workshop sessions.
