Phases • B1.1 0.8 miles 1400 cy 24 Hour Traffic control • B1.2 0.8 miles 1400 cy 24 Hour Traffic control • A1 1.57 miles 2900 cy • A2 1.57 miles 2900 cy • F1 1.15 miles 2100 cy 24 Hour Traffic control • F2 1.15 miles 2100 cy 24 Hour Traffic control

Traffic Control • Two types for PCCP • Road Closed to thru traffic Sections E, D, C, B2, A • 24 hour bi-directional traffic control B1, F

Mix Design • Included 4# of Macro Fibers • Was designed to get breaks in 30-36 hours due to the construction timetable • Plant was located At US Aggregate Flat Rock Site

Plant Site

Basic Outline of Method • Shift into traffic control • Profile Mill • Shoulder Mill • Asphalt Patching • Shoulder Treatment • Install Bars • Concrete Pave 6” overlay 8” on shoulder • Install Shoulder Cap
