NEW Asphalt Bid/Mix Specifications – Guidance and Web Tool
WisDOT and WAPA have worked together to deliver guidance on new asphalt bid requirements in Wisconsin.
Beginning in 2016, WisDOT will require that asphalt mix and PG binder prices be combined into one bid item. In addition, submitted bids must use an updated nomenclature that streamlines the various components of the bid item.
We have collaborated to provide the following support and resources as the new system goes into effect.
