Surface Treatments for Concrete
The US Army Corps of Engineers initiated in 1984 a research program designated Repair, Evaluation, Maintenance, and Rehabilitation (REMR), one of the work units being the evaluation of...

Rx for Dam Repair
Bernard asserts the growing importance of maintenance to extend the service life of dams as more and more of them reach or exceed their design lives. He describes renovations to Easton...

Design of Roller Compacted Concrete Pavements
This paper reviews some of the differences between roller compacted concrete and conventionally constructed concrete pavements. These differences require additional consideration during...

Fly Ash Utilized in Concrete—Technology Update
Fly ash is frequently utilized as a pozzolanic substance in Portland cement concrete. Levels of such utilization, a reflection of current practice/technology, seem to have stabilized at...

Water Use Management in the North Slope Arctic Coastal Plain (abstract)
On the North Slope, water is dependent on accessibility as well as availability. Lakes which to do not freeze to the bottom, may support fish populations. To protect this resource, lakes...

Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...

Drying Out
Treatment plants are most efficient when they're treating waste, not water. Spurred on by increased fuel prices, a number of new technologies have been developed that can...

Pipeline Frost Heave Predictions Using a 2-D Thermal Model
Chilled structures founded on initially unfrozen soils cause a zone or 'bulb' of frost to develop with time. This time period may be of seasonal duration, as...

Soil Strength Recovery Using a Clegg Impact Device
The research described in this paper uses the Clegg Impact Device to determine the relative strength of a soil, and describes how this information can be used to develop the strength recovery...

A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...

Geomembrane Liner Performance in the Arctic
A geomembrane liner must be selected not only on the basis of its chemical compatibility with the substance to be contained, but also on the basis of its physical performance characteristics...

Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...

Route Thaw Settlement: A Probabilistic Evaluation
A methodology is outlined for assessing potential differential thaw settlement effects on structures due to permafrost degradation along transportation routes in the offshore, nearshore,...

Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...

Strudel Scour: An Arctic Seafloor Scouring Process
Strudel scour is an arctic phenomenon which occurs every spring when the fresh-water rivers melt and inundate the sea ice cover of the arctic sea. This fresh water flowing out over the...
