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...

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...

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...

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,...

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...

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...

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....

Infrastructure Damage Modeling with GIS
This paper describes the use of a geographic information system to model damage to a municipal water distribution system. In a demonstration application detailed attribute data on components...
