Asphalt Mix Testing and Design

Designs and tests hot mix asphalt (HMA) mixes produced at private and county-owned plants throughout eastern Wisconsin and Michigan. OMNNI is one of the few laboratories in Wisconsin, and the onlyconsultant laboratory in northeastern Wisconsin that is nationally accredited for HMA testing through the AASHTO Accreditation Program. OMNNI’s lab is also Wisconsin DOT qualified with “express HMA mix design submittal” status and a Michigan DOT qualified mix design laboratory.

For over a decade, OMNNI has provided HMA mix designs, quality control mix testing, quality assurance mix testing, placement testing and consulting for over 250 projects in Wisconsin and Michigan. Work is performed for most of the HMA mix producers in eastern Wisconsin, as well as the Wisconsin DOT and many counties and municipalities.

Feasibility Study: The Use of Crumb Rubber
Modifier in Asphalt Paving Mixes
Outagamie County Highway Department, WI

Conducted a feasibility study to evaluate the various methods of incorporating crumb rubber into asphalt mix. The study included anticipating the effects of a crumb rubber modifier on mix properties, investigating crumb rubber and asphalt mix production and construction considerations, and estimating the net cost of using the County’s scrap tires in asphalt paving mixes. Costs and recommendations were provided.

The county is currently testing the application in a one-mile segment of College Avenue (CTH CA) from Casaloma Drive to Outagamie County Regional Airport. OMNNI provided mix designs, quality control testing and pavement density testing prior to and during construction.

Porous Asphalt Pavement Study
Wisconsin Asphalt Pavement Association

OMNNI conducted a study to provide information to quantify the effect of asphalt binder content and binder type (unmodified vs. modified) on the durability of the porous pavement mix. The test results were compared to national standards for porous pavements and open graded friction courses to help the Wisconsin Asphalt Pavement Association develop mix design guidelines for porous asphalt pavements in Wisconsin.
