The Pontis Bridge Management System
A committee of the Federal Highway Administration and six of the United States has completed a network-level bridge management system, called Pontis, to optimize budgets and programs for...
Traffic Accident Analysis System
While statistical data on traffic accidents are invaluable in devising effective traffic safety measures, the number of data items and samples are vast and they must be processed and edited...
Changes to the AASHTO Guide for Design of Pavement Structures
At this juncture of the SHRP-LTPP program, it is appropriate to discuss the potential impacts that SHRP-LTPP results could have on the future AASHTO Guides for the Design of Pavement Structures....
Connecticut I-95 Incident Management System
Strategies for minimizing the impact of freeway incidents on traffic flow/congestion are reffered to as 'incident management'. The incident management process involves the following: reducing...
Rehabilitation/Upgrading of Under-Rated or Deteriorating Single or Multi-Span Structures Using Corrugated Steel Pipe, Tunnel Liner Plate or Structural Plate
This paper cites advantages of the rehabilitation/upgrading of under-rated or deteriorating culverts or bridges using corrugated steel pipe, tunnel liner plate or structural plate. Among...
Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...
Bonded Concrete Overlays for Rehabilitation of Continuously Reinforced Concrete Pavement
As a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA), significant funding is now available for the rehabilitation of the nation's Interstate highway system....
Automated Crack Detection System Implementation in ARAN
An automated road surface crack detection system has been integrated into the Automated Road Analyzer (ARAN). The acquisition system features controlled lighting through strobe lights...
Evaluation of a Large Aggregate Asphaltic Layer in an Airside Pavement
A new analytical method of designing large aggregate asphalt mixes (LAM) was used to design a thick asphalt base layer for an aircraft taxiway. The results of an analysis on the material...
Use of Surface Treatments on Airport Pavements
Asphalt is generally used as the surfacing for flexible airport pavements with airline passenger jet aircraft. In Australia and its neighbouring territories, surface treatments (seals)...
The Fundamental Gap in Urban Transportation
This is not a technical paper. It is perspective paper, designed to detail the failure of current urban transportation strategies and call for new thinking and action responsive to the...
Quality Control: Bridge Steel Fabrication and Erection
This paper examines the Quality Control Program Plan (QCPP) developed by Frederic R. Harris, Inc. (FRH) for fabrication and erection inspection of over 5,448,000 kg of AASHTO Fracture...
Implications of ISTEA on the Implementation of APMs
The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, approved 372-47 in the House and 79-8 in the Senate, is a landmark legislation in the area of transportation. Through...

Hassle-Free Bridge Rehab
Engineers involved in Cleveland's Main Bridge rehab invoked whatever was necessary to keep area traffic moving and the bridge closure period to a minimum. They helped change...
In Search of Better Load Ratings
Typically, engineers must make a number of subjective assumptions regarding loading and response behavior when they develop a load rating for civil structures. As a result, many unknowns...
LRFD for Timber Structures
The use of load and resistance design (LRFD) methodologies is increasingly becoming the standard analysis procedure for engineering design. The concrete industry has used a variation of...
Lateral Loading Curves from Pressuremeter Tests
The large drilled shafts for the proposed Klamath Falls Bridge, which are to be founded in diatomaceous silts, were to be designed to withstand earthquake induced large cyclic loading....
Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....
