USE OF CRUSHED STONE SCREENINGS IN HIGHWAY CONSTRUCTION (ABRIDGMENT)
Crushed stone screenings are the finer fraction of stone products and normally contain particles 4-5 mm (0.15-0.19) in size or smaller. As natural sand sources are being depleted, the demand for this manufactured sand will increase. Two advantages of stone screenings for highway construction are their uniform grading and crushed faces. The particles provide great shear resistance when compacted. Such products are available and are suitable for mixing with coarse aggregate in a variety of aggregate mixes or for use in upgrading weak soils. They are very effective for stabilization since their nonplastic nature and clean particle surfaces permit full use of the stabilizing agent. For example, cement-stabilized bases using stone screenings and portland cement require less cement than regular soil-cement mixes of equal rigidity. Also, their use in asphaltic concrete mixes produces higher ultimate triaxial strengths.
