• Abstract:
  This report documents the surface recycling of 7.688 miles (12.37 km) of Interstate 55 in Pike County from ; about 10 miles (16.1 km) south of McComb to the Louisiana state line. The recycling equipment was by ; Remixer Contracting Co., Inc. of Austin, Texas. The existing pavement was first heated, milled to 1.25 in. ; (31.75 mm) depth, rejuvenator and virgin mix was added, and then the 1.5 in. (38.10 mm) of recycled mix ; was re-laid and compacted. The daily productions proceeded with few problems on the four field inspection ; days and averaged 0.69 lane-miles (1.11 lane-km) per day. ; The reuse of the existing asphaltic concrete pavement is desirable because of the decreasing supply and increasing ; costs of raw materials. The remixing leaves the final grade almost the same, which allows the user ; the option of rehabilitation only one lane of a multi-lane highway and is a good safety factor. ; Structural integrity was measured with the Dynaflect and Falling Weight Deflectometer. The South Dakota ; profiler was used to obtain before and after International Roughness Index values. ; Materials from the test roadway were sampled and compared with other roadways for viscosity, penetration, ; and ductility, percent voids, density, specific gravity, percent asphalt, gradations, and resilient modulus. ; After six years of service life, the recycled pavement proved its competency to perform comparably to conventional ; hot-mix. This study found that pavements using reclaimed asphalt concrete material in the wearing ; course mixes perform as well as pavements with normal mixes. The cost of each type of pavement was ; found to be almost the same dollar/SY amount.
