Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the results and conclusions gained from the three demonstration projects. The paper concentrates on the characteristics of the processed material, equipment production, and the cost of the operation. Samples taken from windrows during the crushing operation were tested to determine hardness and gradations before and after crushing. The test results are included in the appendix. Cost varied from $6.38 to $18.83 per cubic yard, including roadbed preparation, crushing and blading. Rocks and boulders to?16-inch (406 millimeter) maximum size were crushed. The processed material has a maximum size of 2 to 3 inches (50 to 75 millimeters).?The product produced by the crusher offers a viable alternative for aggregate on a road surface, particularly as a road surface cushion material, where the quality and expense of standard crushed aggregate are not warranted.
