Hot Mix Asphalt Technology - January/February 2008 - (Page 36) Illinois Tollway Tests RAP continued Wis., to complete a portion of the HMA construction. Rockford Blacktop and Rock Road have embraced the Tollway’s higher RAP research activities, and are producing test mixtures to include in the analysis. Table 1 summarizes the mixtures that are being proposed for analysis. At the time of publication, two of the SMA mixtures and the N70 19.0mm binder have been successfully produced and placed. The production and placement process of each test mixture occurs over two production days. Each day involves placing about 500 tons of HMA. Mix test results from the first day of production (voids, ignition burns for asphalt content and gradation, and in-place density) are evaluated to determine if the produced mixture matches the mix design. Small mix adjustments can be made going into the second day’s production. It is during the second day’s production that mix samples are obtained for conducting additional analysis. Several other aspects of the Tollway’s higher-RAP research are evident in Table 1: • Three SMA mixtures are being evaluated, each with a different type of coarse aggregate. • The SMA mixtures will be a continuation of the research the Mix Type 1 2 3 4 5 6 7 8 9 SMA SMA SMA N70 19.0 N70 9.5 N50 19.0 N50 19.0 N50 Base N50 Base PG grade GTR 76-22 GTR 76-22 GTR 76-22 58-22 64-22 58-28 58-22 58-28 58-22 FRAP Category* 1 1 1 2 2 2 2 2 2 FRAP % Fine/Coarse 15/0 15/0 15/0 25/15 15/10 10/30 10/30 10/30 10/30 Coarse Agg type Crushed Gravel Trap Rock Steel Slag Cr.
