NCAT Section S1 combined 50% RAP with 4.1% SIP-1111™ and recorded no visible cracking with less than 3.5 mm rut depth after one year and about 4 million ESALs.
Four northeast Iowa projects put SIP-1111™ to work across 24 miles of cold-in-place recycling, recycled hot mix, county roads, and a municipal main street.
