Instructions for the protection of the environment. The

machine contains valuable materials. Take the

discarded apparatus and accessories to the relevant

recycling facilities.

Soil, which has been disturbed or new in ll, subbase and blacktop, will have small voids or air pockets which, if not compacted, will

lead to one or more problems occurring.

1. As traf c crosses the surface of an uncompacted area, the material is compressed. This leads to subsidence of the top surface

as the material lls the voids.

2. A similar situation occurs with static loads on uncompacted ground. The load (e.g. a building) will sink.

3. Materials with voids are more susceptible to water seepage, leading to erosion. Water ingress may also cause the soil to

expand during freezing temperatures and contract during dry spells. Expansion and contraction is a major cause of damage to

building foundations and normally leads to the structure requiring underpinning.

Compaction increases the density of the material and therefore increases its load bearing capacity. Reduces air voids and therefore

reduces the risk of subsidence, expansion and contraction, due to ingress of water.
