The results of prior research conducted on precast prestressed panel subdecks for use in the construction of bridge decks are reviewed and summarized. This construction technique utilizes the precast panel subdecks as the forming for the cast-in-place upper portion of the deck. After placement of the upper portion of the deck the panels become an i

An evaluation of the results of a two-year survey of incidents of wrong-way driving on Virginia highways revealed that the majority of them originated at diamond type interchanges. On-site investigations of a number of the interchanges at which instances of wrong-way driving had been noted suggested several improvements. The report discusses measur

To determine people's reactions to bridges painted in colors as white, yellow, green, blue, red, brown, black, and aluminum, two test bridges were selected in Charlottesville, Virginia. One was painted a different color each month and the other was kept a single color for comparison. After each painting, interviews were held with three different gr

The subject of this report is an air quality prediction model for highways, AIRPOL Version 2, July 1973. AIRPOL has been developed by modifying the basic Gaussian approach to gaseous dispersion. The resultant model is smooth and continuous throughout its entire range, which adds mathematical credence to its applicability. AIRPOL has the capability

Cold weather paving specifications were developed from work by Corlew and Dickson, who used a computer solution to predict the cooling rate of bituminous concrete. Virginia had used a minimum atmospheric temperature as a criterion; however, it was evident that other factors had a significant effect, so the computer solution was considered as a poss
