Pedestrian malls - streets that have been dedicated to pedestrian use only - are a popular urban renewal tactic for stimulating economic growth in deteriorating central business districts by attracting commercial retail business. Because of benefits they bring to the downtown road system, pedestrian malls have been included as a means of route dive

This report demonstrates that the probability of violating a "not to be exceeded more than once per year", one-hour air quality standard can be bounded from above. This result represents a significant improvement over previous methods of ascertaining the impacts of pollution sources. Such methods essentially estimated the expected annual maximum co

The procedure used for producing precast slabs of polymer impregnated concrete (PIC) and described in this report was generally satisfactory from an operational standpoint. A strength loss of 14%, attributable to the drying step, was observed in PIC cylinders; however, residual strengths for this class of concrete were satisfactory. The freeze-thaw

In general, there was little evidence that the public information countermeasure was effective in increasing awareness or overall knowledge, or in improving attitudes. The major exceptions to this were the self-reported increase in bystander intervention and self-reported decrease in drinking and driving.

This investigation was undertaken in an attempt to identify the causes of low densities in asphaltic concrete placed on 9 projects. The most prevalent cause, which accounted for the difficulties on 5 of the 9 projects, appeared to be improper mix design and/or variability within the aggregate. The use of travel speeds in excess of that specified fo

This report discusses the construction and initial condition of the Virginia Department of Highways and Transportation's first three bridges built with glulam panels on steel stringers. The data show that superstructures with glulam deck panels are more expensive than the conventional alternative of solid plank on steel stringers. It is felt that i

The purpose of this study was to evaluate Virginia's maintenance management system and to recommend modifications directed at improving it. The study revealed that (1) the current system of allocating maintenance monies is based upon centerline mileage rather than the quantities of maintainable items, (2) the area superintendents' desired level-of-
