Concrete Change
The concrete industry has an array of options when it comes to recycling. Incorporating glass, chicken feathers, palm fronds, sludge, crushed computer casings or other recycled materials...

Geotechnics of Industrial By-Products
Large volumes of industrial by-products are generated each year by U.S. industries, and most are landfilled as solid waste at considerable expense. However, many by-products have desirable...

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...

Geotechnical Performance of a Highway Embankment Constructed Using Waste Foundry Sand
A highway embankment was constructed near Auburn, Indiana, using waste foundry sand (WFS) as a demonstration project for the Indiana Department of Transportation (INDOT). Laboratory testing...

Recycled Materials for Embankment Construction
Obtaining good quality soils at reasonable costs for use in embankment construction is becoming difficult and hence, attention is directed towards finding alternative materials. On the...

Behavior of Construction and Demolition Debris in Base and Subbase Applications
The design performance of a pavement system is evaluated based on the predicted number of load repetitions it will be subjected to throughout its service life. Mechanistic pavement design...

The Safe Disposal of Fly Ash in Pavement or Earth Structures Not Requiring High Strength Materials
Highway agencies throughout the country face the challenge of safe disposal of various waste products in pavements and earth structures. Some of these waste products can be hazardous to...

Crushed Hydrated Fly Ash as a Construction Aggregate
Hydrated fly ash (HFA) is being produced in Texas by first adding water to Class C fly ash and allowing it to hydrate in curing pits for several weeks. HFA typically attain unconfined...
