      Hofener, Scott A. (1983-2)
      In December, 1980, a solar heating system was installed at the Oklahoma Department of Transportation Maintenance Building in Chickasha, Oklahoma. The system is based on an air type flat plate solar collector with an ...

    • Splices in tensile reinforcing bars 

      Segner, E.P. Jr. (1965-8)
      The purpose of this project was to provide information on the relative merits of the various methods of connecting tensile reinforci ng bars in reinforced concrete construction. This project consisted of two parts. In Part ...

    • Stability and Permeability of Proposed Aggregate Bases in Oklahoma (FHWA-OK-09-05 2196) 

      Khoury, Naji N.; Zaman, Musharraf M.; Ghabchi, Rouzbeh; Kazmee, Hassan (2010-5)
      Aggregate base is an important component of a pavement structure. It supports the asphalt concrete (AC) layer and reduces the wheel load-induced stresses on the underlying layers. It also functions as a drainage layer. ...
