Structural Design on Ductile Iron Pipe
The thickness class designation for Ductile Iron pipe has been changed to a pressure class designation in the 1991 revision of the C150/A21.50 ANSI standard. However, the same conservative...
Estimation of Reliability Parameters for Rehabilitation of Pipelines
This paper presents fundamental principles of estimating statistical characteristics of the elements of urban underground infrastructure networks, which provides a basis of statistical...
Installing a Raw Water Line by Microtunneling
Construction began in 1991 on a new water treatment plan for the Towns of Cary and Apex, with B. Everett Jordan Lake as a water source. Installation of two 1,400 mm raw water lines approximately...
Evaluation of a Proprietary Tape Coating Alternative for the 157 Mile Ivie Pipeline
A two part evaluation of alternative protective coating systems for the 157 mile Ivie pipeline was made. In Part I, an evaluation was made on the suitability of a proprietary tape coating...
An Evaluation of Fiberglass Pipe Made by Three Different Manufacturing Processes for use in Water Transmission Projects
Fiberglass pipe is made primarily using continuous filament wound process, discontinuous helical filament wound process, and centrifugal cast process. Some 40 countries around the world...
Gas Pipeline Fitness-for-Service Investigation
A delta reclamation district's plan to add significant fill on their levee caused great concern for the integrity of a critical PG&E 22-inch (559 mm) gas transmission line which...
Analysis and Design of Direct Burial Sections of San Diego County Water Authority's Pipeline 4 Extension
The pipeline 4 extension is one of the San Diego County Water Authority's Phase I projects that will run for about 13 miles. Majority of this new pipeline will be 96 inch in steel and...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
Microtunneling of Vitrified Clay Pipe in the United States
Vitrified clay pipe (VCP) has been used for centuries to convey waste water away for cities. In Europe and Japan, VCP has been used in the microtunnelling process for longer than 10 years....
Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...
Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...
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...
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...
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)...
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...
Anti-Icing...The Liquid Answer
In the fall of 1984, Great Salt Lake Minerals and Chemicals Corporation of Ogden, Utah (a major producer of Salt and Allied Chemicals) introduced their 'Alternative Deicers' to Washington...
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,...
