Standard Installations: A Synopsis of the ASCE Standard Practice for Direct Design of Buried Precast Concrete Pipe
In 1970, the American Concrete Pipe Association (ACPA) began a long range research program which focused on the behavior of buried concrete pipe. The research resulted in the comprehensive...
High-Speed Railways and Development in Japan
There is a need to develop an environmentally friendly railway in response to society's needs, implement high-speed operations on existing tracks, and develop a high-quality, high-speed...
Controlling Corrosion in Bridge Structures
The overall objectives of the Structures Research Area of the Strategic Highway Research Program (SHRP) were to provide methods to protect chloride-contaminated concrete components against...
Gyratory Testing Machine Usage in Monitoring HMA Quality
This paper describes research conducted by the Mississippi Department of Transportation to investigate the potential of the U.S. Army Corps of Engineers' Gyratory Testing Machine (GTM)...
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...
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...
Electrochemical Treatment and Protection: Lessons Learned
Corrosion is recognized today as one of the major contributors to the deterioration of steel reinforced concrete structures. Two electrochemical techniques, chloride removal and cathodic...
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...
Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
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,...
Durability of High Performance Concrete
The freeze-thaw durability and the resistance to chloride penetration of high performance concrete (HPC) developed for highway applications were investigated. This paper summarizes the...
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...
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...
Early Field Experience with SUPERPAVE
Specific pavement studies of newly constructed, reconstructed or rehabilitated (resurfaced) pavement sections were used to provide an estimate of the relative influence of key pavement...
The Proof is in the Pavement
A technique known as statistical quality assurance (SQA) lets DOTs quantify pavement quality by setting statistical guidelines for the work they will accept. SQA is a distinct departure...
RCC: Rehab Results
Thirty dams have been modified with roller compacted concrete in order to provide additional spillway capacity and for safe overtopping of embankment dams. In the national dam safety inspection...
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...
Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...
