Abstract:
A study evaluated the performance of a 10 in. (250 mm) thick unbonded concrete overlay project on Indiana's I-69, from SR-18 to 6 mi (9 km) north of SR-18. The concrete overlay was placed in 1986 and 1987. To monitor the pavement condition, pavement roughness, friction and deflection were measured and visual inspection of the pavement distresses were conducted. After eight years in service, the pavement was still in good condition. The pavement deflection, friction, and roughness tests indicated that the pavement had sufficient strength, good skid resistance, and good rideability. The skewed joints in this project functioned well. Compared to conventional joints, the skewed joints resulted in smoother driving, less vehicle vibration, and less noise.
