Statewide Investigation of Flexible Pavements
The study was initiated in 1955 to develop information on the deflection behavior of several selected flexible pavements of different design, by means of the newly developed Benkelman beam test. In 1960 the study was expanded to include all newly constructed flexible pavements. Routine observations included Benkelman beam deflection measurements for a 11.2-kip wheel load in both wheel paths of one lane. Data on pavement structure design, construction, traffic and environmental conditions were compiled. Information on the roadbed material was compiled from physiographic and other soil maps and from construction records. A more intensive study was made of one of the originally selected pavements (U.S. 40 West) that has performed exceptionally well. Seven test sites were included. These sites were selected to represent the range in deflection and performance encountered throughout the 16-mile length of the test section. One or two 12-inch diameter cores were drilled and samples of each pavement component and the roadbed soil were obtained at each site. Flexure and sonic modulus tests of beams, and permeability tests of cubes sawed from the cores were conducted. The void content of the mix and the penetration of extracted asphalt cement were determined. Hveem stabilometer tests were made on soil samples. (Author)
