Paint thickness gauges are widely used to measure the thickness of the paint coat on any surface. Mostly their application is industrial, with the widest range of uses arising in the construction industry. They are used for compliance purposes, measuring coating thickness on materials and many other uses. There are many types of paint gauges available in the market. What works best for your application needs to be carefully selected. Here is an overview of types and applications of paint thickness gauge . Types of gauges While these gauges cannot be distinctively classified into categories, there are certain variants available which help in measuring the thickness of the coating on different surfaces. The digital gauge is popular due to its ease of use and direct output. One can place this device on the surface to be measured for thickness and get the results on the LED screen as a convenient read-out with preferred units of measurement. The second kind of thickness gaug

California Bearing Ration is the test which is carried out, in a very indirect way, to find out the thickness of pavements and layers in road construction. The principle lies in using a penetration equipment on a prepared soil sample and then taking ratios of it with a standard value; this results in an empirical curve which is then analysed to work out the thickness of pavements. In this blogpost, you will get to know the basic procedure of California Bearing Ratio (CBR) test . Procedure: ·          Weigh the empty mould for accurate results. ·          Assemble the mould and attach the collar over it. ·          Add water to the specimen and start compaction as per the Standard Proctor or the Modified Proctor test. ·          When compaction is complete, remove the collar and use a cutting edge to level off the surface of specimen. ·          Weigh the mould and compacted specimen, and work out the bulk density of the specimen. ·          Take a sample for moistu
