Perform Feasibility Study on Use of Innovative Tools and Techniques to Accelerate Pavement Construction

The Texas Department of Transportation (TxDOT) faces a massive increase in pavement reconstruction projects over the next 10 years especially with the passage of the Proposition 7 funding. However, most of the roadways needing reconstruction and widening are in the metro areas where traffic handling and user delay costs are a major expense. On major projects, one common approach taken by designers is complete reconstruction where the existing pavement structure is removed down to the sub-base layer and a completely new pavement structure is built. This is extremely expensive and very time consuming. Full reconstruction is known to cost double that of in place recycling or rubblization, and it's known to take at least three times longer. Recent case studies from other states have demonstrated that tremendous savings in time and money are possible with in place recycling or rubblization. Over the past 10 years, TxDOT has developed a series of NDT tools which can be used to structurally evaluate existing facilities. These technologies provide meaningful data on the structural adequacy of existing main lanes, shoulders, and detour routes such as frontage roads. The successful interpretation and implementation of these technologies in the pavement planning stage will provide the designers with options for how to utilize existing materials and minimize traffic handling costs. This study will focus on demonstrating the available tools to designers in TxDOT's major urban districts to determine how the results generated can can be more widely used in the plan preparation and project scheduling process.
