A moisture meter is an important instrument which is used in various industries. It is used for finding a   level of moisture content in the materials. The authorities who build homes and buildings, solely rely on these instruments to find out the moisture level in the soil. It helps in identifying the possible problems and damage to the structures due to the moisture in the material. Flooring contractors use these moisture meters for determining an   ideal conditions while fixing a floor over the concrete slab or another floor. Most of the moisture meters are used to calibrate with wood and provides a more precise reading in case of moisture content in the wood. The ranges of this scale vary from 5% to 40%. When the moisture content in materials other than wood is detected, a scale of 0 to m100 is generally used. Here 0 is the bone and 100 is saturated. Moisture meters include LED indicators. These indicators are linked to the reading in percentage form for ...

This is a test to measure the penetration strength of ground, subgrades and base courses during new roads constructions. It was developed by California Department of Transportation to make sure roads are constructed on perfect areas of the earth. The first step is to measure the pressure needed to penetrate soil or surface in a bid to avoid unnecessary destruction of land.  ASTM Standards D1883-05, D4429 and AASHTO T193 are the standards used in describing perfect CBR outcomes on soils and rocks. Importance of CBR Test You have found roads degrading in quality and cracking easily after some time of usage. That is simply due to the weight being exerted on that particular road by the vehicles passing on it. CBR is used to measure the load bearing capacity of soils in a bid to construct roads that will be durable and safe for the purposed carriage means. It can even measure load bearing capacity of airstrips to make sure only the appropriat...
