Testing Result For Crusher Run Cbr

Feb 15, 2005nbsp018332I had two CBR tests run in a crushed rock gravel, gapgraded with about 20 percent fines. It was produced by a rock crusher onsite, and acts a lot like screenings. The CBR results are a concave shape for the entire curve up to 0.5 inch deflection.
