Shakedown of Pavements Under Moving Surface Loads
(American Society of Civil Engineers, 1984)Procedures for the analysis of the shakedown of pavements are developed. The approach employed models the elastoplastic behavior of a horizontally‐layered continuum subjected to repeated moving loads, and permits the ... -
Discussion of “<i>Protection of Pipelines Subject to Surcharge Loads</i>” by Eugene M. Kovach (November, 1982)
(American Society of Civil Engineers, 1983) -
Social and Environmental Impacts: Edens Project
(American Society of Civil Engineers, 1983)The Edens Expressway project, one of the largest reconstruction projects involving an urban, high volume, Interstate freeway, required an indepth assessment of the various socioeconomic and environmental impacts from the ... -
Pedestrian Safety Through Work Zones; Guidelines
(American Society of Civil Engineers, 1983)The current state‐of‐the‐art and current practices followed for pedestrian accommodation in highway work zones, and suggested guidelines to improve pedestrian safety is briefly described. Literature searches revealed only ... -
Environmental Impact Assessment: Highway Location
(American Society of Civil Engineers, 1983)Two major factors involved in the selection of an alinement for a highway are addressed. The first is the identification of those environmental concerns that should be considered in the alinement selection phase; and ... -
Lift System for Raising Continuous Concrete Bridges
(American Society of Civil Engineers, 1983)Due to road resurfacing a significant number of highway bridges throughout the nation violate underneath clearance requirements. A bridge lifting/monitoring system was developed as one solution to this problem. The system ... -
Minisized Automobiles and Roadside Appurtenances
(American Society of Civil Engineers, 1983)The effectiveness of roadside safety appurtenances under impact with minisized automobiles is investigated. The vast majority of existing roadside hardware have been qualified under guidelines which have not considered ... -
Absorption in Manufactured Soil Aggregates
(American Society of Civil Engineers, 1983)Absorption characteristics of cylindrical soil aggregates manufactured using three soils of different mineralogy and composition and fired to temperatures between 1,922° F (1,050 °C) and 2,282° F (1,250 °C) were assessed ... -
Methods Used to Evaluate Highway Improvements
(American Society of Civil Engineers, 1983)This study provides information to state‐level planners for rational decision‐making regarding the enhancement of the analytical process for setting highway improvement priorities. Arizona's analytical procedure, a sufficiency ... -
Flight Frequency Determination
(American Society of Civil Engineers, 1983)An attempt has been made to determine the flight frequency between two cities. The economic effects achieved by the earner using a particular flight frequency level is measured through the average load factor value. The ... -
Precast Repair of CRC Pavements
(American Society of Civil Engineers, 1983)This report presents a summary of the results of an investigation into the design, fabrication and installation of precast concrete panels for the repair of continuously reinforced concrete (CRC) pavements. Factors affecting ... -
Erratum: “Transit Performance Evaluation Model” by Richard P. Guenthner and Kumares C. Sinha (July, 1982)
(American Society of Civil Engineers, 1983) -
Inflation and Highway Economic Analysis
(American Society of Civil Engineers, 1983)Increases in funding highway construction and maintenance programs have failed to keep pace with inflation over the past decade. It can be shown that the reduction in funding is an indirect result of inflation. Under these ... -
Finite Element Analysis of Jointed Concrete Pavements
(American Society of Civil Engineers, 1983)A finite element method programmed for a computer is presented for determining the stresses and deflections in multiple slabs on elastic solids. The method is an extension to that presented in a previous paper by applying ... -
Comparative Analyses of Rigid Pavements
(American Society of Civil Engineers, 1983)Stress conditions in concrete pavements were analyzed using the finite element method for slabs on liquid and elastic subgrades. The study consisted of the following parts: (1) The effect of the efficiency of load transfer ... -
Loading Mode Effects on Pavement Deflections
(American Society of Civil Engineers, 1983)Pavement deflection data collected using static (the Benketman Beam), vibratory (the Road Rater), impulse (the Falling Weight Deflectometer), and vehicular loading have been used to identify and explain the factors affecting ... -
Truck Suspension Models
(American Society of Civil Engineers, 1983)Laboratory experiments on an International ACCO 1810A truck rear suspension unit are used to assess the validity of mathematical models for the tire and spring. Best results are achieved with tire and spring models that ... -
Landsat and Water Quality Model Verification
(American Society of Civil Engineers, 1983)It has been shown that satellites can provide an image of water quality patterns over a large constantly‐changing coastal area and that these data can be used to infer circulation and calibrate real‐time water quality ... -
Predicting Transit Ridership in Response to Transit Service Changes
(American Society of Civil Engineers, 1983)This paper reports the development of a simplified form of the multinomial logit model and its application to the prediction of travel mode shares for a range of transit service changes. An earlier version of this model, ... -
Optimal Layout for Branching Distribution Networks
(American Society of Civil Engineers, 1983)A branching network consisting of several sources and demand nodes is considered to find its optimal geometrical layout. Initially a one‐source two‐demand‐node network is considered and for it, optimality criteria are ...
