    Sprinkel, Michael M
    1982-01-01 | PDF
    The installation of a thin polymer concrete overlay on the Beulah Road bridge demonstrates that an overlay of low permeability and high skid resistance can be successfully installed by maintenance forces with a minimum of disruption to traffic, approximately 8 hr. per lane, and at about half the cost of alternative service-life-extending measures. ...
  • Evaluation of Overlaid Bridge Decks with GroundPenetrating Radar
    Evaluation of Overlaid Bridge Decks with Ground-Penetrating Radar
    Clemeña, Gerardo G.
    1982-01-01 | PDF
    There is an urgent need for methods that can be used to rapidly and nondestructively determine the condition of an old concrete deck beneath an asphaltic concrete wearing course. In recognition of this need, the technique of ground-penetrating radar was investigated. In practice, microwave-frequency impulses of about 1.1 nanosecond pulse width are ...

    Two test sections, one on new construction and the other on a maintenance resurfacing project, were installed in the fall of 1980 to evaluate the proprietary product Chem-Crete. Laboratory tests and dynaflect and density measurements were performed on the experimental and control mixes and the performance was evaluated over a two-year period. Ravel ...
  • Effectiveness of six noise barriers on I495 final report
    Effectiveness of six noise barriers on I-495 : final report.

    Noble, David F
    1982-01-01 | PDF
    While measurements made by the Virginia Highway and Transportation Research Council, other departments of transportation, and the Federal Highway Administration have generally shown that acoustical barriers perform as predicted, public acceptance has often been less than unanimous. Some complaints that barriers do not seem to reduce noise levels ha ...

    This report has been prepared for the benefit of these persons involved in highway construction who are not familiar with coal ash terminology. The information presented will, it is hoped, assist them in avoiding confusion relating to the general characteristics and potential uses of the various types and classes of ash. The report covers, very bri ...
  • An evaluation of the impact of the Virginia driver improvement program on negligent driving 12month report interim report
    An evaluation of the impact of the Virginia driver improvement program on negligent driving : 12-month report [interim report].
    Lynn, Cheryl
    1982-01-01 | PDF
    This study sought to evaluate the impact of the four basic treatment combinations of the rehabilitation component of the Virginia driver improvement program. It was found that receipt of a warning letter from the Division of Motor Vehicles had no effect on the subsequent driving records of program participants. Drivers attending the group interview ...

    The Virginia Department of Highways and Transportation has been designated the administering agency for UMTA's Section 16(b)(2) program of capital grants to private, nonprofit organizations for the provision of transportation to the elderly and handicapped. The Department's procedures for purchasing communication equipment and the utilization of th ...
  • Estimates of the economic and human consequences of motor vehicle accidents in Virginia during 1980
    Estimates of the economic and human consequences of motor vehicle accidents in Virginia during 1980.
    Regan, Daniel John ;
    Atkins, Alden L.
    1982-01-01 | PDF
    The purpose of this report is to describe the cost of motor vehicle accidents in two ways first, by identifying the cost components and quantifying them, and second by showing the severity of such accidents in terms of human suffering. Although many statistics are kept concerning the causes of motor vehicle accidents, few are kept concerning the re ...
  • Heatcurved girders deflections and camber loss during and subsequent to bridge construction
    Heat-curved girders : deflections and camber loss during and subsequent to bridge construction.
    Hilton, Marvin H
    1982-01-01 | PDF
    The present AASHTO bridge design specifications require that additional camber be built into steel girders that are to be heat curved. The additional camber is provided to allow for subsequent losses due to the dissipation of residual stresses imposed by the heat-curving process during fabrication of the girders. Many bridge engineers and steel fab ...
  • Problem identification for Virginias highway safety plan
    Problem identification for Virginia's highway safety plan.
    Rauth, Susan G
    1982-01-01 | PDF
    Problem identification is recognized as an important component of highway safety planning. Under the NHTSA/FHWA concept, problem identification is the first step in program planning and in the development of effective countermeasure programs. The annual highway safety plan (HSP) is the major planning tool used by the Virginia Department of Transpor ...

    Vinson, Ted S.
    1981-12-01 | PDF
    Repeated load diametral test systems are experiencing increased use to determine resilient properties of asphalt concrete and admixture stabilized materials; they have not been used extensively to determine the resilient properties of unbound materials. This is due in part to the fact that comparative studies between the properties obtained with th ...
