Polymer modified binder sprayed seal trials: construction report

This report describes the planning and construction of Australian field trials which will measure of the relative performance of polymer modified binders (PMBs) used in strain alleviating membranes in sprayed bituminous sealing. Issues addressed in the report include evaluating and selecting test sites, observing and measuring their existing condition, design, sampling and testing of materials, and a plan for ongoing monitoring. The latest Austroads PMB specification framework AGPT/T190 has revised PMB classifications and includes the introduction of a new grade that is yet to be produced and field validated. Field validation of the performance of these current generation PMBs will ensure appropriate binder selection enabling longer seal life and reduced maintenance costs. Nationally conducted trials will also avoid costly duplication of effort that would otherwise occur by conducting individual trials in various jurisdictions, thereby reducing both jurisdictional and industry costs, and reducing time delays in introducing improved binders into periodic reseal programs around Australia.
