Chicago Automates Expressway Lanes
Chicago motorists will soon reclaim another rebuilt expressway in October with substantial completion of a $450 million, 7.5 mi portion of I90/94, the John F. Kennedy Expressway. The two...

America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...

Pittsburgh Goes International
The size of the new $785 million Pittsburgh International Airport�900 developed acres�is twice the size of the city's Golden Triangle business district but occupies only a...

Integration of a Municipal Pavement Management System with a Geographic Information System
This paper describes the use of a Pavement Management System (PMS), and the integration of the pavement condition data with a Geographic Information System (GIS). In June 1988, the Pavement...

Using License Plate Survey Data in Transportation Planning Applications
This paper is a presentation of the methodology used by the Baltimore Regional Council of Governments to conduct a multi-faceted study for the Maryland Aviation Administration, which operates...

Spreadsheet Pavement Management Systems for Local Roads
Changes in administration and funding levels at the local government level are continuing to illustrate the need for information systems to aid the county engineer or public works director....

Automation of Design at the New Denver Airport
This paper outlines an innovative approach to automating the roadway design process by linking design and drafting with multiple software programs and taking advantage of the strengths...

Grading Design Using CADD: Denver International Airport Roadways
Using the terminal access roadway site for the new Denver International Airport as an example, this paper outlines a method for automating the preparation of grading plans and computation...

Bonded Polyester Concrete Overlays Used in California
Bonded polyester concrete overlays have been very successful in California in restoring and preserving bridge decks from damage by road salts. The polyester concrete system has been employed...

Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...

Quality Control and Constructability of Slabs on Grade With Expert Systems
Constructability and quality control problems associated with the construction of slabs on grade are many. They vary from problems associated with cracking, scaling, dusting and spalling,...

PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...

Building Object-Oriented Systems for Diagnostic Problems in Civil Engineering
In recent years, rehabilitation and renovation of existing buildings and roads have grown to occupy a significant share of all civil engineering projects. Proper timing of rehabilitative...

Computer Aided Analysis/Design of Overlays in Cracked Road Pavements
In this contribution CAPA, a user-friendly, PC based, finite element system, capable of analyzing and dimensioning pavement overlays is presented. Because of the generality of the finite...

Simulating Paving Fleets with Non-Stationary Travel
Proper selection of equipment and fleet size can yield substantial savings in both time and cost. A simulation model of asphalt-paving operations is presented and impacts of non-stationary...

Modular Software for Editing Paper Drawings
Revising, tracking and storing large format engineering drawings has always been an expensive and complex problem for large industries. The management problem became much more complex...

Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...

Promoting Management Systems Within Organizations
The major effort during the years in which pavement management emerged as an accepted practice was making refinements to the technical models and techniques in the systems. For example,...

Benefits From Improved Management of Pavement Facilities
Effective management of pavement facilities can provide several benefits both the agency and the travelling public over the long term. The benefits achieved from improved rehabilitation...

How to Get Local Public Works Agencies to Use Structured Infrastructure Management Approaches
As more agencies consider adopting infrastructure management systems, the lessons learned in developing and supporting the use of current systems should be used to structure the support...
