California bearing ratio Wikipedia

The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. The results of these tests are used with the empirical curves to determine the thickness of pavement and its component layers. This is the most widely used method for the design of flexible pavement.

tests, a CBR mould fitted with a cutting shoe was inserted into the undisturbed areas of the more cohesive of the materials to obtain a CBR test specimen, see Figure A5 of Appendix A. This sampling method was not viable for the more granular materials, and so the CBR test specimens for these were prepared in the laboratory.

Does Granite Need To Be Sealed? Here's How To Tell If A

I asked Jeremy how often homeowners need to apply a sealer to their countertops, and his reply was that the installers can apply a granite sealer that will last 20 years or longer — so be sure to ask for that, if you're involved in the installation process. Generally speaking, most people reseal granite countertops every 1 to 3 years.
