• Abstract:
  Due to difficulties associated with the maintenance of highways constructed in urban settings, the expedited construction of durable Portland cement concrete (PCC) pavement has become a necessity. To obtain a durable PCC pavement, a number of parameters should be considered. Since most urban roads experience excessive traffic, the desire of highway agencies is to open a newly constructed highway to traffic as soon as possible. Due to heavy traffic, several layers of high-quality or heavily stabilized materials are normally placed during construction. For the Texas Department of Transportation (TxDOT), this consists of one or more layers of stabilized subgrade and base, a layer of ACP to act as a bond breaker, and a PCC slab. The large number of layers may to cost-effective from the standpoint of agency costs; however, the number of steps involved may increase the construction period increasing user costs borne by the motoring public. It may be possible to minimize the number of layers without compromising the performance of the pavement by either thickening or using innovative high-strength materials. This may increase the construction cost, but, considering the user costs, it may be in the best interest of TxDOT to follow this option. In this project, a methodology is proposed to mainstream the construction of highways in urban settings.
