J-Band application began at 3:30pm on June 2. Temperatures recorded at that time were ambient 78ยฐF; existing binder surface 102ยฐF and material on board the distributor was 315ยฐF. The application continued through June 3 with a start time of 7:30 a.m. Temperatures recorded at that time were ambient 63ยฐF; existing binder surface 66ยฐF and material on board distributor was 320ยฐF. Band width on this project was targeted at 18โ wide. A target rate of 1.80 lb/ft was โspecedโ for the 2โ IL-9.5. Band width was found to be a consistent 18.5โ band.
