Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...

Anatomy of Asphalt
Two main factors will combine over the next several years to alter the composition of asphalt pavements, which make up more than 90% of the paved roads in the U.S. First, a major research...
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Every Penny's Worth
Value engineering has been used in the construction industry since the 1960s, but highway projects have sometimes been thought of as too simple for VE studies. Now, with the increasing...
Caring for a Covered Bridge
Today the quaint Cornish-Windsor covered bridge (winner of this year's Outstanding Civil Engineering Merit Award) doesn't look much different than it did when...
Response of Ductile Iron Pipelines at Parkfield, CA to Loma Prieta Earthquake
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed at Owens' Pasture near Parkfield, CA. The site was...
Evaluation of Automatic Earthquake Shutoff Valve Performance and Recommendations for Future U.S. Standards
Increasing interest of local and state government has developed in recent years regarding legislation requiring automatic shutoff valves for natural gas lines as well as lines containing...
Performance of Unreinforced Masonry Buildings During the Newcastle Earthquake, Australia
On December 28, 1989, an earthquake of Richter magnitude 5.6 shook the city of Newcastle. Newcastle is situated on the east coast of Australia only 100km north of Sydney. Eleven deaths...
Using Real-Time Location Information for Hazardous Materials Shipments
Real-time location information on shipments of hazardous materials can be used to update routing decisions while the shipments are in transit. The effects of unforeseen delays, accidents...
Marina Del Rey: 30 Years of Environmental Impact
Marina del Rey - the world's largest man-made recreational boating harbor - also holds primacy in pollution. Marina del Rey is home port to more than 6,100 vessels in wet...
Innovative Breakwater Designs on the Great Lakes
Extensive investigations have recently been undertaken to support the development of rubblemound breakwater designs for new marinas at Kenosha and Sheboygan, WI, both located on the west...
Assessment of Cyclical Wave Damage for Small Basin Harbors
Since the construction of Oceanside Harbor in Southern California in 1963, continuous wave penetration into the inner harbor has caused significant damage to dock systems, revetments,...
Operation and Maintenance Plan for Marinas
A operation and maintenance (O&M) plan for marinas is presented to describe the process and establish basic parameters that can be used as guidelines to more comprehensive site-specific...
Lessons from Hurricane Hugo: Recommendations for Marina Operation and Design
Hurricanes are not new to South Carolina, but with the recent development of the coast, many new and unseasoned boaters have located in the area. Since Hurricane Hazel in 1954, South Carolina...
Pavement Materials for ASTOVL Aircraft Application
Jet blast impingement on concrete is a problem today and will worsen when the new vectored-thrust aircraft become operational. Ground erosion has already been observed under the auxiliary...
Modified Asphalt Binders for Military Airfield Pavements
This report documents a laboratory-based research effort to determine the effects of asphalt modifiers and alternate binders on asphalt airfield pavements. The modified binders were tested...
Concrete Mixture Evaluation and Acceptance for Air Field Pavements
Evaluation of the strength of portland cement concrete using flexural strength and compressive strength tests is examined. Problems with the use of flexural testing in the field are discussed...
