Project description

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.
