2009/8/3The test site is prepared and loose material is removed so that the 75 cm diameter plate rests horizontally in full contact with the soil sub-grade. The plate is seated accurately and then a seating load equivalent to a pressure of 0.07 kg/cm2 (320 kg for 75 cm diameter plate) is applied and released after a Get price

Subgrade Preparation

Fine grained, cohesive clay soils can also be used as a subgrade construction material. Native clayey-silt or silty-clay glacial tills are often found in lining subgrades. These materials can be worked, graded, compacted and trimmed to create a smooth, level and competent surface, however, all angular and sharp rocks or stones should be removed from the surface or picked out of the prepared Get price

Horse Arena Base Information

A clay layer below your footing will not create the necessary stability for the footing above and also runs the risk of integrating into your arena surface. Even though you may compact the clay during installation, eventually with use over time the surface will break the clay apart causing an unstable surface and small dust particles in your footing.

Everything You Need to Know About Installing a Sub

The sub-base material is the foundation of an artificial grass installation; it is what will give your artificial lawn structural stability. A solid, well-compacted sub-base is crucial in providing sufficient strength to allow foot traffic and items of furniture to be placed upon the artificial lawn. Get price

What are the materials used in a highway road?

Pavements can get broken down into three primary components - the subgrade, or the soils below the pavements; aggregate, a layer of sand, gravel, and clay used to provide a mostly rigid surface; and the wear surface, typically consisting of concre Get price

Sub

The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and prevent settlement and channelisation - the phenomenon common on cheap installations of block paving, where two 'ruts' develop in the paving.
