10,000 gal. asphalt storage tank was equipped with a solar heating system and instrumented to determine its effectiveness over a 12.5-month period. An evaluation of the data indicated that the solar system conserved 25,126 kWh of electrical power during the monitoring period. At a cost of $0.0387 per kWh, savings of $972.24 were realized. A present

This report updated previous reports on the impact of raising and lowering the legal drinking age. The legal drinking age for beer in Virginia was lowered from 21 to 18 years in 1974. The percentage of all crashes that were alcohol-related increased significantly after 1975 for persons under 16, 16 to 19 years, and 20 to 24 years. Such increases we

This report investigates the use of Value Engineering for selecting work zone channelizing devices. Presented first is a State-of-the-Art review of available channelizing devices and their relative performance. Next, an overview of the Value Engineering problem-solving approach is presented. The paper then demonstrates how the Value Engineering app

The findings from this study were based on limited data. Requests for candidate structures for the inspections indicated that relatively few suitable bridges were available. Only 6 of those bridges could be skid tested. A further limitation was that, since the texturing specification was relatively new, the effect of traffic wear over a substantial

The report examines the influences of communication on transportation from various points of view. First, the historical influences are discussed as they occurred in the United States between 1776 and the present. Second, probable influences to the year 2010 are presented. Third, the influences are examined through responses to a questionnaire obta

Seven-day volume counts were made at fast-food restaurants with drive-thru service, convenience markets, condominiums, drive-in banks, high-rise apartments, planned unit developments, mobile home parks, day-care centers, churches, suburban motels, and post offices throughout Virginia. Typical traffic patterns at the sites were determined from the c

Results of usual tests for specification compliance and special tests to show viscosity-temperature susceptibility and ductility penetration relationships for asphalts supplied for use by the Virginia Department of Highways and Transportation in 1983 are reported. The results to date have not revealed any asphalts with unusual properties. Differenc

Twelve bridges with latex modified concrete (LMC) overlays ranging in age from new to 13 years were studied and their general condition found to be good. The half-cell and chloride data were inconclusive because background data were not available for the older overlays, but the data should be useful some 5 to i0 years from now if similar data are c

The condition of county roads and city streets was assessed using two methods-(1) by questionnaire to the cities and counties and (2) by using Department of Highways and Public Transportation records. There was some discrepancy between the two methods in actual mileage and bridge needs; however, the results were within reason. Therefore, it is sugg
