Environmental testing and evaluation of stabilized wastes, performance of stabilized materials, and new aggregate tests. A peer-reviewed publication of the Transportation Research Board TRB.

The 18 papers in this volume are arranged in three groups. The first two groups of papers discuss issues related to stabilized materials, and the third group of papers relates to aggregate testing. The seven papers in the first group describe investigations related to materials such as fly ash, AMD sludge, phosphogypsum, FDG gypsum, fluorogypsum, oil and gas well sludge, and MSW combustion bottom ash. The investigations focus on leaching behavior of the waste materials and what effects cement, lime, fly ash, and bitumen stabilizion have on the characteristics of the leachates. The second group of five papers presents information on laboratory characterization and field performance evaluation of stabilized bases. The third group of six papers describes engineering properties of waste materials and natural aggregates. Information on new developments in performance-oriented aggregate testing is presented.
