Mitigation of Void Development under Bridge Approach Slabs Using Rubber Tire Chips
The problem of void development under bridge approach slabs has been correlated to the use of integral abutment bridges (Schaefer and Koch, 1992). This void development then causes settlement...
Speedy Backfilling for Old Mines
In November 1992, the U.S. Bureau of Mines, in cooperation with the Office of Surface Mining (OSM), used two recently-developed pneumatic backfilling devices to completely fill an abandoned...
Diffusion Barrier Transport Properties of Unsaturated Paintbrush Tuff Rubble Backfill
Diffusion coefficients (D) were experimentally determined in unsaturated tuff gravel to evaluated the effectiveness of tuff gravel and rubble as a diffusion barrier to ionic transport...
Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...
Subsidence Abatement Projects in Wyoming?An Overview
Abatement projects were undertaken to prevent or minimize further subsidence in Wyoming communities. The paper gives a brief historical background on the mining activity in Wyoming. Subsidence...
ECPT Investigation of a Slurry Trench Cutoff Wall
ECPT (electronic cone penetration testing) was used to investigate a soil-bentonite backfilled slurry trench cutoff wall at Calamus Dam in Nebraska, The wall was tested shortly after its...
Innovtive Designs for Low-Level Nuclear Waste Disposal Trenches
Shallow land burial of low-level nuclear wastes presents many problems that are within the scope of civil engineering analysis and design. This paper presents the results of a U. S. Nuclear...
Sewer Construction Inspection and Testing
Sewer construction testing is the final portion of the team effort that started with the goal of meeting the requirement for a sewer system for the protection of health and environment....
Need a Dependable Backfill?Try a Flowable Fly Ash
Flowable fly ash is a relatively new cementitious structural backfill material. It can be used in water or in the dry and will flow into place without the usual labor-intensive activities...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
Pile Construction Practices in Arctic Regions: State-of-the-Art
Pile installation techniques in cold regions include drill and slurry, and driven methods for foundation designs. In the past, piles used for structural support in permafrost have consisted...
Design and Construction of Long-Span Metal Culverts
Long-span metal culverts are built of corrugated-metal plates bolted together. They have spans exceeding 15 ft. Principal applications include use as drainage structures, grade separations,...
Nuclear Testing of Utility Trench Backfill
For many years, Westchester County municipalities were resigned to the fact that compaction of utility trenches could not be done satisfactorily and that settlement and road failure would...
Committee on Backfilling in Public Rights-of-Way Final Report
The report is concerned primarily with evaluating types and properties of soils in the West and North sections of the city and county of St. Louis, field testing and evaluation of the...
