7 HISTORY

8 9 DIFFERENT STRUCTURES Applications: roads, streets, motorways, airfields, earth and rock fill dams, railway embankments and foundations for buildings. Other applications include: parking areas, storage yards, sports areas, industrial and residential areas, harbour constructions, reservoirs and canals.

10 SOIL PROPERTIES What does soil consist of? Important material parameters Type of soil, grain size distribution, particle size Particle shape Water/moisture content

11 13 GRAIN SIZE DISTRIBUTION ISO ,002 0, Clay Silt Sand Gravel Cobble 200 Boulder <15% Coarse <12% 15-40% Mixed 12-50% >40% Fine >50% Clay and silt Sand Gravel Cobble and boulder ASTM D ,075 No 200 4,75 No

12 APPLICATIONS Impact Force Clays Silts Vibratory Force Sand Gravel Rockfill Particle Size Particle Size Small Larger Small Larger Frequency Frequency

13 IMPACT COMPACTION Impact compaction relies on a high impact force. The force of the impact produces a pressure wave in the soil which generates high pressure at depth as well. A large impact force against the surface can be obtained by dropping a heavy weight lifted by a crane. Tampers work with relatively large stroke height and generate comparatively large impact forces giving a good depth effect and a better ability to compact cohesive soils than vibratory plates.

14 VIBRATORY COMPACTION Vibratory compaction achieves higher densities and better depth effect than static compaction => more efficient and economical than static compaction

15 STATIC COMPACTION Static compaction equipment uses the dead-weight of the machine to apply pressure on the surface to compress the ill material. Static pressure in the soil rapidly decreases with increasing depth => limited depth effect
