Long-Term Pavement Performance Program for Years 1992-1997: A Strategic Plan
The Federal Highway Administration (FHWA) began operational management of the Strategic Highway Research Program's (SHRP) Long-Term Pavement Performance (LTPP) program on July 1, 1992....

Steps to a Mix Design Solution for Better Asphalt
Three primary products will be delivered at completion of the Asphalt Research Program of the Strategic Highway Research Program, a performance based asphalt binder specification, a performance...

How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...

Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...

Concrete Bridge Protection Repair & Rehabilitation
A methodology for the selection of cost effective solution(s) to the protection, repair, and rehabilitation of concrete bridges in chloride-laden environments is presented. The methodology...

Selecting Bridge Protection and Rehabilitation Options
This paper describes a recently developed procedure for use by bridge engineers making protection or rehabilitation decisions for concrete bridges. The methodology determines the most...

Future Improvements for Design of Flexible Pavement Structures
The first set of data analyses on the National Pavement Data Base (NPDB) derived from the Long-Term Pavement Performance (LTPP) activities have been completed. The results from sensitivity...

Design Implications for Concrete Pavements from LTPP Analyses
Among the original objectives of the Long-Term Pavement Performance (LTPP) study of the Strategic Highway Research Program (SHRP) were the evaluation of existing design methods for pavements,...

An Evaluation of the Strategic Highway Research Project Packing Handbook
The objective of this paper is to present the use of the November 8, 1991 SHRP C-206 report entitled `Packing Handbook - A Guide to the Optimal Gradation of Concrete Aggregates'. The purpose...

Cathodic Protection for Protecting Prestressed Concrete
Due to the good effect of corrosion protection of reinforcing steel bars, even in concrete highly chloride contaminated, cathodic protection for concrete structure now carried out as a...

Long-Term Pavement Performance (LTPP) Program in Japan
Japan's `Manual for Design and Construction of Asphalt Pavement' is based on technical results from the AASHO Road Test in 1960's. Strategic Highway Research Program (SHRP) is a much bigger...

Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...

Managing Maintenance from a Business Viewpoint
Today's sophisticated maintenance management systems allow supervisors to plan, schedule, monitor and evaluate the maintenance function at a level and speed our predecessors heretofore...

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...

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....

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...

Computer-Aided Liability
Civil engineers are using computers more than ever to help them streamline analysis and design, boost productivity and cut costs. Often they rely on mass-marketed software such as Autodesk...

Accuracy Requirements for GIS-Based Seismic Risk Assessments
Accurate assessments of potential earthquake damage and casualty risk are essential to the design of seismic hazard mitigation policies and seismically oriented engineering practice. More...
