Compaction machines. Compaction machines apply forces to increase soil density. Some equipment applies only static forces, which include pressure and kneading produced only by the dead weight and configuration of the machine itself. Such static forces affect only the top layers of material, and their impact is felt only to a limited depth.

The soil under this class was unsuitable for subgrade construction. The qualities of stabilized soil were evaluated using the Atterberg limit, compunction, and CBR test. Crushed stone dust was used to stabilize the soil in stepwise proportions of 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% by dry weight of soil.

Mushroom soil should not be used to completely replace soil but should be mixed. A ratio of 75% soil and 25% mushroom compost is often a good mix for most gardens. Mushroom soil is also particularly great for lawns. By adding it to newly seeded lawns, it will help the seeds germinate as they retain water.

Backfill materials that are commonly used are described below with their engineering properties. 1. Coarse-grained soils. Coarse-grained soils include gravelly and sandy soils and range from clayey sands ( SC) through the well-graded gravels of gravel-sand mixtures ( GW) with little or no fines. They will exhibit slight to no plasticity.

California bearing ratio is the percentage of stress a soil specimen can resist for a certain amount of penetration relative to the value of stress of which a standard soil could resist. Basically, the value is an indicator of the strength of the soil. CBR= P s P std. ×100% C B R = P s P s t d. × 100 %.
