This amendment has shown very promising results. In an attempt to ensure minimum settlement of the paving after construction, the in situ material which had been backfilled behind the quay wall excavation as part of the Phase1 reclamation, was compacted by means of 45passes or 90runs of an impact roller delivering an energy of 25KJ.

Feb 24, 2019· Mining Roads much reduced number of 'passes' required to achieve compaction - hence reduced construction unit costs. Typically, a 25kJ (or larger) impact roller would be used, towed by a large 4x4 tractor unit. The degree of compaction specified in a layer is usually 'until no further movement is seen under the roller'.

Tomando como ejemplo la compactación de impacto del rodillo de impacto de doble rueda 25kJ en la carretera de escoria y grava, después de que el rodillo sea accionado a una velocidad de 12 km/h durante 30 veces, la presión vertical media de tierra a la profundidad medida de 0,8 m es de 1366kPa, Lo que es equivalente a la fuerza de impacto ...
Some people been debating about the impact force on a bike of a bike rider riding off a 6 foot drop to a flat landing. Mainly the debate is about if speed would lessen the impact force on the bike because of the impact angle. So, if a bike rider was to ride off a 6 foot drop, would it lessen the impact force on the bike jumping off the 6 foot ...
The non-circular masses are thus caused to rotate and generate a series of high impact and high amplitude blows that are delivered to the surface of the soil at a relatively low frequency of 90 to 130 blows per minute. The energy per blow varies between 10kJ and 25kJ depending on the type of compactor being utilised.

This has led to the development of the 25kJ three-sided Impact Compactor based on the principle of high energy and amplitude. Compaction of subgrades is usually controlled by a density and method specification, i.e. 90% of mod AASHTO density and construction in layers of less than 200mm.
Impact Compactors operate at speeds of up to 5 times faster than conventional plant. Increased operating speeds coupled with thicker lift compaction allows impact compactors to compact up to 10 times more volume than conventional plant. Typically 7,000-9,200 m2 (8,300 - 12,000 yd2) per shift on layerworks.
Figure 1. Rolling mechanisms of a 3-sided 25kJ impact roller. According to Bousinesz the depth of influence is a function of the contact pressure and the geometry of the roller. The huge contact areas of the drum allows for improvement down to depths of 5.0m. The contact stress measured during impact range from 300kPa to 1.2Mpa
This has led to the development of the Impact Compactors, namely the 25kJ three-sided Impact Compactor, based on the principle of high energy, high amplitude and low frequency.

The name Impact Roller or Impact Compaction Roller can be misleading in that it implies a rolling cylinder as used in conventional vibrating and static road rollers. Impact rollers are characterised by non-cylindrical multisided geometrical Drum or Module.
