In a bid to ensure cost-effective highway construction practices, highway agencies constantly seek ways to accelerate project design and delivery through implementation of innovative contracting and procurement practices. The concept of warranties, which is one of such promising practices,...

A commonality among state Departments of Transportation is the inability to complete projects on time and within budget. This project assessed the extent of the problem of cost overruns, time delays, and change orders associated with Indiana Department of Transportation (INDOT) construction...

INDOT initiated a study to investigate Performance Based Contracting of maintenance operations. One of the main impetus for the study is that INDOT started a ten year road building program called Major Moves that will add over a 1900 lane miles to the current network. With this addition and...

Throughout the United States, state highway revenue, which is dominated by receipts from fuel taxes, has failed to keep up with expected investments required for infrastructure preservation and improvement. The reasons for this trend include the increasing fuel efficiency of vehicles, slowing of...

With ever increasing traffic loadings, highway pavement maintenance needs continue to outpace the availability of resources, and transportation agencies seek cost-effective maintenance practices. This study investigated the impacts of maintenance treatments in the short-term and maintenance...

With ever increasing traffic loadings, highway pavement maintenance needs continue to outpace the availability of resources, and transportation agencies seek cost-effective maintenance practices. This study investigated the effectiveness of maintenance treatments in the short-term and the cost...

Researchers and engineers continue to ponder over the reliability of construction cost forecasts made at the early stages of project development. After a project has been incorporated in the statewide transportation improvement program, increasingly detailed estimates of its cost are prepared at...

The evaluation of transportation projects has traditionally been carried out in the context of economic efficiency, in terms of savings in travel time, vehicle operating cost, and safety. The wider and longer-term effects on economic development (i.e., job, income and business growth) are a...
