  A Soil Inclinometer is an instrument used to measure a heave or settlement of soil. These instruments are used to determine the soil's slope concerning forces of gravity acting upon it. They also help detect any subsurface movement to predict any drastic changes in soil structure.  The Process A plastic tube (the casing of the Inclinometer) is mounted in the soil to be measured. The tube is then filled with cement or bentonite grout. The casing is lined with four orthogonal ruts that assist in gliding the Inclinometer into the soil. The probe also has orthogonal sensors that detect and record the probe's angle concerning the soil structure. The deviations are based on the casing, which may be horizontal or vertical. These probes are equipped with sprung wheels to hold them in place while the survey is underway. Points to note about Soil Inclinometers: These devices are usually light and easily portable. They also display immense durability and very high accurac

A CBR test or the California Bearing Ratio test is a form of penetration assessment to gauge the subgrade levels of roads and pavements. These kinds of structures, strength is crucial, and the CBR test helps to maintain them to avoid casualties. The strength of the structure is measured by evaluating the pressure required to infiltrate a piece of the soil with a standardized plunger. The readings are used to detect any drawbacks in the soil structure and appropriately rectify the problem. The process A plunger of standard measurements is used to penetrate the soil, and the pressure required to do so is measured and recorded. A standard crushed rock is also penetrated to equal measure, and the pressure required is again recorded. The pressure required to penetrate the soil is then divided by the pressure required to penetrate the crushed rock. Usually, CBR tests are conducted in multiples of 3 on each site to maintain accuracy. The CBR value of the surfaces varies based on its ri
