gravel compaction layer thickness Description

Compaction Guide | Glavel

For hard surfaces and low gravel layer thicknesses, lightweight devices tend to be suitable. For softer surfaces and large insulation Glavel layer thicknesses, heavier devices are required. The compression ratio of the insulation ballast layer is 1.3 : 1. This measure must be adhered to. The compaction is to be stopped when the target value is reached. Further compaction increases the material

Soil Compaction Handbook - Multiquip Inc

Static compaction is confined to upper soil layers and is limited to any appreciable depth. Kneading and pressure are two examples of static compaction. Vibratory force uses a mechanism, usually engine-driven, to create a downward force in addition to the machine's static weight. The vibrating mechanism is usually a rotating eccentric weight or piston/spring combination (in rammers). The

The thickness is measured by making holes into the compacted layer at three points at each cross-section; two on the sides and one at the center. The average thickness so measured is taken as the thickness of the compacted layer. Alternatively, the thickness can also be determined by taking the differences in the level before and after the construction of the layer into consideration.
