• Abstract:
  The performance record of continuously reinforced concrete pavement has been the subject of discussion for numerous research papers during the last few years. This paper constitutes a report on the early service life characteristics of a continuously reinforced concrete pavement in Comal County, Texas. Gage plugs were placed longitudinally along the pavement surface at spacings of 20 inches in two short test areas covering distances of 28 feet and 38 feet, respectively. The movement between adjacent gage plugs was measured by the use of a 20-inch Berry Strain Gage at various periods during the early life of the pavement. In conjunction with these studies of movement, measurements of air temperature, transverse crack width, and concrete properties were performed. A test section approximately 1500 feet long was observed for the development of the crack pattern for a period of one year. The experimental data were used to analyze the interaction among air temperature, pavement age, and concrete properties, as these variables influence the development of the crack pattern in a continuously reinforced concrete pavement.
