Seal Design Austroad

The AUSTROADS Provisional Sprayed Seal Design Method (Revision 2000) was the principal outcome of a major seal design project which was itself a response to practitioner's concerns about the inconsistent performance of seals designed using the previous AUSTROADS (1990) seal design method. During 1991-93, seal trials were constructed throughout. Austroads sprayed seal design is an empirically derived method, meaning it was extrapolated from experimental data generated by observation and experience. However, New Zealand's sprayed seal design method is based on quantitative measurements of surface texture change under traffic.

The designs were prepared in the planning stage of each leg of the trials, and reviewed on site by the designer and spray crews for appropriateness to the local conditions at the time of construction The design of the sprayed seal surfacing was conducted based on the latest Austroads sprayed seal design method, and consideration was given to aggregate embedment and conversion of ALF load to equivalent design traffic. The selected seal, a double seal with latex modified emulsion binder, was applied using a special process enabling.

This ensures we use the correct ratio of spray seal to aggregate with every job to guarantee your driveway sealing lasts the journey. Our site preparation methods also play a big part in durability, as the bitumen laid is only as good. Projects have included investigations into bitumen alternative binders, studies of how polymer modified binder properties can be used to predict road performance, the effects of cutter levels on aggregate wetting in sprayed seals, improvements to the Austroads sprayed seal design method for low volume roads, and investigations into how cutter.
