• Description:
  The Stone Matrix Asphalt (SMA) experimental feature on SH-119, from SH-52 East to Longmont, is the Colorado Department of Transportation's (CDOT's) first attempt under contract to construct test sections for evaluation. The project successfully demonstrated the design, production, and placement of the European SMA. The research experiment on the project consisted of placing 11,000 tons (9,979,200 kg) of SMA using three different mix designs (two polymer stabilized mixtures and one fiber mixture). The two polymers were 1) Vestoplast S from Huls America and 2) PM-ID from Koch Materials Co. The fiber mixture used a cellulose fiber in pellet form from Arbocel. The material specifications used for the design of the SMA were adequate with a few exceptions. Several plant modifications were required to add the mineral filler and additives. Production through the plant was reduced significantly because of the addition of mineral filler. The rate of production was virtually cut in half from the normally expected 250 tons (226,800 kg) per hour to 150 tons (136,080 kg) per hour. Field performance data will be evaluated on an annual basis. Results will be available in approximately 3 years. Based on the European torture tests, it is expected that the SMAs will have very good field performance with respect to rutting and moisture damage.
