Four northeast Iowa projects put SIP-1111\u2122 to work across approximately 24 centerline miles in 2025: County Road C14 in Fayette County, County Roads B45 and X28 in Clayton County, and Washington Street in Volga. The program combined cold-in-place recycling, recycled hot mix, county-road scale, and a small-town main street.<\/p>\n

Four sites in one construction program<\/h2>\n

County Road C14 covered 8.6 miles south of West Union. Clayton County’s B45 and X28 projects covered a combined 14.7 miles. Nearly half a mile of Washington Street carried the program through Volga’s business district.<\/p>\n

Washington Street in Volga<\/h2>\n

Nearly half a mile of Washington Street brought the regional SIP-1111\u2122 construction program through Volga’s business district. This municipal main-street project paired the program’s recycled-material strategy with a finished surface serving homes, businesses, and community destinations.<\/p>\n<\/section>\n

Cold recycling below, recycled hot mix above<\/h2>\n

SIP-1111\u2122 was used in foamed asphalt for a 100% recycled cold-in-place base layer across the Clayton and Fayette County work. The hot-mix asphalt surface used SIP-1111\u2122 with about 30% recycled pavement.<\/p>\n

Fayette County used 182 fewer tons of foamed asphalt than expected, a reported 67% reduction. After the cost of SIP-1111\u2122, the county recorded approximately $97,000 in foam-binder savings. In Clayton County, the B45 and X28 hot-mix work used approximately 33 tons of soy rejuvenator.<\/p>\n

More existing pavement, less new binder demand<\/h2>\n

The construction sequence recovered the existing pavement for the base and carried recycled material into the wearing course. For agencies, that means a rehabilitation strategy built around material already in the road. For producers, it demonstrates SIP-1111\u2122 in both foamed-asphalt recycling and recycled hot-mix production within one regional program.<\/p>\n
