  • Properties of Crushed Red-Bed Soft Rock Mixtures Used in

    Dec 28, 2016· The special properties of red-bed soft rocks, such as slaking or softening in water, should be full considered in materials for road construction. Based on the above physical and mechanical properties of crushed soft rock matrix, the red-bed soft rocks have good engineering properties for subgrade after being crushed and compacted.
