This report is a part of the continuing post-construction evaluation of a Sulphur extended asphalt field trial located on U. S. 69 near Lufkin, Texas. It contains a discussion of the background and methods of testing. In-situ results and laboratory test results on cores are presented in tabular form with respect to pavement age.

Because the rolling behavior of a car with a V2 term is described by a non-linear differential equation, it had been assumed that no closed-form solution existed and that we would have to use a numerical integration procedure (e.g. Runge-Kutta) to solve the associated differential equation. Using a closed-form solution in PROFILE and SPEEDCON allow

This assessment of the automobile transportation system examines the automobile as a mode of personal transportation and considers issues and policy options pertaining to vehicles, highways, and related industries, services, and institutions. The assessment was authorized in February 1976 by the Technology Assessment Board, which approved a program

Herein we implement an approximate headway control algorithm similar to that outlined in Note 6, using some of the energy formulas described in Note 7. The algorithm is an iterative search procedure in which the highest exit velocity for the second car is calculated, subject to the constraint that sufficient headway exists at the point of switching

A simple design procedure for a Dowty equipped yard has been developed. This procedure has been developed from information contained in several papers (see references at the end of the not), and may not coincide with Dowty Co. procedures, if any exist.

Yard configuration should have been determined with site selection, since different yard designs have their own space requirements. The pros and cons of three common yard layouts are presented, followed by a detailed presentation of Engineering criteria used for geometric design with the associated mathematical formulas.

The literature reviewed to date has revealed three basic speed control systems in use in foreign classification yards. These are: Clasp retarders using target-shooting logic, Hybrid of conventional retarders with a “car mover”, and Quasi-continuous control.

The operating philosophy of a railroad dictates the organization of its data system. ConRail (CR) claimed for example, that yard personnel mainly want a track list, whereas those outside the terminal mainly want to trace cars. At the Union Pacific (UP), data systems are subservient to the needs for running the railroad. For this reason, UP has gone

This study of the Oregon State Highway Division's surfacing design procedures was undertaken to determine if the expected service is being obtained from current design practices, and to provide an comparison of different design alternatives to permit an optimum strategy to be selected. The economic analysis included full depth and staged constructi

Noise measurements were taken at six barrier sites: two wooden, two metal, and one concrete barrier were studied; the sixth site had no barrier and was studied to determine the ground effect. The approach was to determine insertion losses by taking simultaneous measurements behind the barrier at different elevations over the same point. In this pro

The research reported here was undertaken in response to a request by the Legislature of Virginia that a study be conducted of state imposed taxes and fees on motor carriers of passengers, the purpose being to determine the effects a reduction in one or more of these taxes would have on state revenue and on the carriers' ability to continue to offe

The results of the early studies of the undermining problems are summarized in the initial portion of this report. Additionally, the design and use of a model sidewalk for testing procedures for preventing undermining are described. Based upon tests with the various model setups the following conclusions are made: 1. Close to maximum compaction of

In view of the Virginia Department of Highways and Transportation's need to conserve dwindling revenues, the Traffic Research Advisory Committee recommended that the feasibility of using unpainted, treated wooden sign posts instead of painted posts be investigated. With the subsequent change to the use of unpainted, treated wooden sign posts, the A

An evaluation was made of the need for changes in Virginia law concerning headlamp usage during periods of dusk and dawn and at times of limited visibility. At the present time motorists are required to turn on the headlamps of their vehicles one-half hour after sunset and to leave them on until one-half hour before sunrise. In addition, headlamps

During the 3-year period from 1974-77, several problems were noted throughout the Pacific Northwest during and after construction of asphalt pavements. These include incompactible mixes, slow setting mixes, flushing mixes, low mix cohesion, and early thermal cracking. This paper reports on attempts to assess and determine those factors most affecti
