Work began on a complete rehabilitation project on Interstate 20 in Roscoe, Texas in July of 1977. 2.9 miles of the project was selected for recycling. Research report 527-1, "Recycling Asphaltic Concrete Pavement," (also published as FHWA-DP-39-11) presents the history of the selected section, construction procedures, mix plant operations, air qua

This report on kinetic bridges is essentially a state-of-the-art study on two types of bridges whose location or physical characteristics are designed to be time dependent. The first type, called a "relocatable bridge", is essentially for use as a temporary structure that must be erected quickly. Many recent examples of this type are described, ran

This project was undertaken for the Virginia Department of Transportation Safety to assess the feasibility of implementing the Data Analysis and Reporting Techniques (DART) computer software system in Virginia. Following a review of available literature, discussion of system implementation and use with federal and state personnel, and a survey of 2

A 1-year fleet test in which 130,000 gal. of gasohol were prepared and used was conducted in the Charlottesville- Culpeper area. The handling and storage of the fuel was monitored, and fuel consumption and maintenance records were maintained on 95 Department vehicles (primarily 1/2-ton pickup trucks and 3-ton dump trucks) that operated a total of 1

There is a need for a tangible way to evaluate the esthetic or visual characteristics of bridges. This report describes such a method based on a numerical experiential rating scale of -10 to +10. Negative values represent unpleasurable responses; positive values, pleasurable ones. Using the rating method proposed seven kinds of bridges are evaluate

In August 1978, bituminous surface treatments in which vulcanized rubber was blended with the asphalt cement were placed on two secondary roads by the Sahuaro Petroleum and Asphalt Company and the Whitehurst Paving Company. The work was jointly financed by the Federal Highway Administration and the Virginia Department of Highways and Transportation

Reduced visibility on the highway due to darkness and adverse weather conditions results in an inability of motorists to readily observe pavement markings. Because raised pavement markers provide increased pavement and roadway delineation, the feasibility of using them has been investigated by the Research Council and the results are summarized in

The Traffic Planning manual is a reference of basic traffic engineering techniques and their potential for improving traffic flow and traffic safety of urban arterial streets and highways. The manual identifies the traffic engineering measure appropriate for consideration in development of transportation improvement plans and programs.
The Virginia Department of Highways and Transportation conducts underwater inspection, maintenance, and salvage activities as part of its routine operations. These activities are carried out by divers from the private sector working on a contract basis and Department employees trained in the use of SCUBA. This manual expresses the Department's atti

This study developed a numerical methodology for the elastic stress analysis of general prismatic beams. The objective was to accurately determine stresses and displacements on a cross section of a beam where the stress resultants are prescribed. Applied loads may include axial force, bending moment, uniform (constant) torsion, constant (transverse

This study was designed to evaluate, on interstate roadways in Virginia, the use of a technique developed in California for estimating or determining incidences of wrong-way driving at off-ramps. Also, information gained from a survey of the available literature on the subject was compiled. Based on data obtained from selected off-ramps in Virginia
