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...
Transit Scheduling Using Computer Graphics
Graphical scheduling has been very popular throughout the world, but until recently, has not been available for a computerized scheduling system. Computerized graphical scheduling systems...
InTransit: Processing and Analyzing Transit Service Data with the Macintosh
InTransit is a database application based on 4th Dimension designed to facilitate the data processing and analysis phases. InTransit, in its present form, can process both ridecheck and...
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...
Computer Analysis of Origin-Destination Survey Data in the State Route 55 Travel Corridor, Before and After the Opening of Carpool Lanes
The State Route (SR) 55 carpool lanes in Orange County were opened for high occupancy vehicles (HOV) usage in November, 1985. Since SR 55 was the first travel corridor in Orange County...
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...
Flexible Pipe Design Revisited
An overwhelming soil factor in the Iowa formula and random deformations at installation affords soil a prominent role in flexible pipe; this, together with a maximal deflection rule make...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
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...
Prediction of Debris Flow Prone Areas and Damage
It is very important when drawing hazard maps to estimate damage to houses from debris flow of certain fixed quantities. A debris flow disaster, which occurred in Kake Town, Hiroshima...
Forces Acting on a Vortex-Excited Vibrating Cylinder in Planar Oscillatory Flow
An experimental investigation into the vortex-excited vibration of a circular cylinder in planar oscillatory flow has been made with emphasis being placed on the amplification of the forces...
Stability Criteria for Revetments
A simplified 'black box' approach is presented for a number of revetment systems for banks and shore protection. The design criteria, based on the physical similarity...
