Types of CBR Testing in Soil Mechanics: Lab vs. Field

In geotechnical engineering, it is important to know how strong the dirt is before starting any building work. The California Bearing Ratio (CBR) test is one of the most popular ways to figure out how strong the soil is. It tells builders how well the soil can hold weight, especially for building roads, sidewalks, and foundations. There are two main types of CBR test: those done in a lab and those done in the field. Each one is useful for different things and has its own benefits.
