Application of Leading Edge PMS Techniques in India
In India there is a pressing need for an efficient system to plan highway rehabilitation and maintenance. A two year project has started in March 1993 to develop a Pavement Management...
Canadian Pavement Management Systems
A large portion of the investment in Canada's road system is in pavement structures. In the 1960's a coordinated national effort toward protecting the investment, through good pavement...
Using a Geographical Information System to Facilitate Implementation of a Pavement Management System
One of the challenges facing local government is the management of its infrastructure. An important part of this process is the development of a pavement management systems to protect...
Programme Management in Highway Region
In the beginning of the 1990's FinnRA suggested decreasing resources for the Lapland highway district whereas the district felt that such a policy would have very harmful long term effects....
The Transrapid EMS Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application. The maglev system uses contactless electromagnetic suspension and three...
Development of a Superconducting Maglev System
The superconducting maglev system features an electrodynamic levitation system (EDS) which enables a super high speed running without any special control device for levitating a coach...
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....
Equipment Systems for the Commercial Production of Modified Asphalt
A considerable amount of research has been centered on various asphalt modifiers and their effect on rheological properties. As the paving industry is now focusing on high performance...
Cost-Effective Pavement Repair Materials
In 1990, as part of the Strategic Highway Research Program's (SHRP) initiative in the highway operations area, a 2 1/2 -year research effort was initiated to study the cost-effectiveness...
Validation of SHRP Performance Graded Binder Specifications Using Field Simulation Testing Equipment
The Strategic Highway Research Program (SHRP) was initiated to improve the effectiveness of laboratory test methods in predicting field performance. European highway agencies are using...
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...
Pavement Repair Automation
Faced with aging and decaying road systems, continual downsizing of government staffs and increasing budget shortfalls, roadway maintenance needs some help. That help is on the way. It's...
Using SHRP Tests to Evaluate CRM Asphalt Pavements
During the recently completed Strategic Highway Research Program (SHRP), there was insufficient time or funds to evaluate the inclusion of waste materials in asphalt paving mixtures. However,...
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...
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...
Application Cases of Slurry Seal in Japan
In Japan, slurry seal began to be used for repairing asphalt pavements at around 1963, mostly for repairs of prefectural and municipal roads. In recent years, however, it has rarely been...
Condition Data Reduction for Pavement Management
A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should...
Using Neural Network to Identify Pavement Structure Based on Radar Output
Knowledge of asphaltic layer thickness and structure are important in many areas of pavement management. Accurate thickness and structure measurements are needed throughout the roadway...
