Paper Mill Sludge Landfill Cover Construction
A considerable amount of experience has been acquired from a number of completed paper mill sludge landfill covers within the United States. This paper focuses on practical guidelines...
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...
Tire Shreds as Lightweight Fill for Embankments and Retaining Walls
Use of tire shreds in three highway projects is described. In the first project, tire shreds were used as a compressible inclusion to reduce pressures on a rigid frame bridge. Earth pressures...
