All Pavement Solutions’ Spray Seal Division was engaged by Blue Mountains City Council to perform an OTTA seal in the Megalong Valley which is a low traffic volume road that sees seasonal tourist traffic loading. The OTTA seal is another option to have in the “tool kitty” for maintenance of the council road network. OTTA seals generally save the asset owner around 30% of the maintenance costs in the project whole of life costing analysis.
OTTA seals are a great option that can utilise recycled materials in the mix design depending on the locally available gravels and percentage of crumb rubber that can be incorporated into the design. Megalong Valley is one of multiple current OTTA projects All Pavement Solutions have recently completed and is performing above and beyond expectation.
