Over 60 city, county, consulting, and IDOT engineers, along with Asphalt Paving Association of Iowa (APAI) contractors, associates, and suppliers, attended an open house on August 1st which highlighted the benefits of asphalt as the most cost-effective, fastest-to-construct, and greenest pavement in Iowa. The open house was a cooperative effort between Tri-State Paving, Dickinson Co. Engineering, and the APAI to feature Dickinson County’s four paving projects which are utilizing warm mix asphalt (WMA), recycled asphalt shingles, and recycled asphalt pavement to complement the emphasis that Dickinson County taxpayers have placed on environmental responsibility.

Attendees were given a tour of Tri-State Paving’s Fostoria plant, where they were able to see the recycled shingles stockpile and WMA foaming device on the plant. On the jobsite, the decreased temperature and lack of smell and fumes was a consistent topic of conversation.
