Learn More Soil and Aggregate Testing Learn More What We Offer Poor workmanship, material quality or installation practices may lead to costly and time-consuming failure . When the crushing value is 25 to 30, the test is insensitive because the weaker material is crushed before the 400 kN load is reached and compacted in a manner that further crushing is reduced. Typical lugeon Values of rock can be given as follows. However, in organic soils, secondary consolidation settlement is more significant. Triaxial test is done to evaluate the mechanical properties of soils such as soil, rock and other granular materials. Rock & natural stone. Before starting the construction some of the materials are tested and others are testing during the construction. The procedure is repeated until it is satisfied.

Flaky and elongated particles are considered unsuitable for base coarse construction as they may cause weakness with possible loading. Since the stress is applied to the specimen along its longitudinal axis, the unconfined compression test is also called the Uniaxial compression test. Further, there are cracks in the rock and water seepages are inevitable if it kept as it is. Due to the high pressure, water moves away to release the pressure while gradually transferring the pressure to the soil. Flaky and elongated particles could create an adverse effect on the concrete and bituminous mixtures. This characteristic is measured by the impact value test. Flaky and elongated particles tend to lower the workability of concrete mix which may lead to long-term durability issues.
