Economic Analysis of Local Highway Maintenance
This paper presents a computer program which uses the present worth of life-cycle costs as a basis to select the most cost-effective maintenance strategy to apply to local highway pavements....

MECHOD: A Mechanistic Overlay Design Program for Flexible Pavements
This paper presents a fully mechanistic asphalt overlay design procedure for use on microcomputers. The procedure is based on fundamental characteristics of pavement layer properties and...

A Microcomputer Based Pavement Design Program
This paper describes a newly developed pavement design program. The performance of a number of pavement structures are projected over the analysis period. Structurally adequate designs...

Interfacing Pavement Management and Design Process
Pavement management systems coordinate all the activities required to provide pavements for the traveling public in a cost efficient manner. Information for the pavement management system...

The Use of Prototyping and Graphical Methods for Road Information and Management Systems
Graphics approaches to Pavement Management Systems offer a substantial aid to the early acceptance of and accessibility to the Road Information Systems presently available. The Apple Macintosh...

Structuring a Microcomputer Based Pavement Management System to Enhance the Probability of Adoption and Continued Use
Diffusion of innovation concepts were used to help structure a microcomputer based pavement management system (PMS) for use by local agency public works personnel in the San Francisco...

Expert System for Flexible Pavement Management Using Lotus 1-2-3
The paper shows how a spreadsheet, LOTUS 1-2-3, can be used in developing expert systems without using any other software. The application program is for selecting a dominant maintenance...

Lapsize Computers and Local Pavement Management
The purpose of this study is to examine the use of a portable computer, the GRIDcase Plus, in local pavement management. A software program in BASIC is developed to run on the GRID, to...

Road Surface Management System for Small to Midsized Communities
This paper describes a Road Surface Management Systems (RSMS) developed by the New Hampshire Technology Transfer Center. Subjects covered include RSMS components, road inventories, repair...

Pavement Inventory and Evaluation Systems Using Microcomputer Data Base Managers
The two most commonly used relational DBMS (Data Base Management System) softwares are Ashton-Tate's 'dBASE III Plus', and Microrim's 'R:Base 5000'. This paper illustrates the use of these...

Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...

Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...

Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...

Sediment Production from Forest Roads with Wheel Ruts
Artificial rainfall was applied to two sets of paired plots 30.5 m long by 1.52 m wide, each set on a different soil type. One plot in each set contained a wheel rut while the other did...

Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...

Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...

A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
