Abstract
Rehabilitation of urban highways is a critical issue confronting Department of Transportation agencies since most states have an inventory of highways that have exceeded their design lives. Delivery of cost-effective projects which minimize delays and traffic impacts of highway rehabilitation is needed. The Construction Analysis for Pavement Rehabilitation Strategies (CA4PRS) is a software program for predicting construction productivity during various closure timeframes for highway rehabilitation. This tool has been used in California and Washington among other states and has proved capable of providing significant scheduling and productivity inputs into early design planning. This study presents the results of evaluating the implementation and use of the CA4PRS by the Georgia Department of Transportation (GDOT) and the Oklahoma Department of Transportation (ODOT) in planning their highway projects. A knowledge inventory survey conducted at GDOT and ODOT is used to assess if the tool could be used in the context of Georgia and Oklahoma. Furthermore, the applicability of CA4PRS is tested in two case studies in an effort to evaluate its potential implementation.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
