What is sub-base course?

The Sub-base course is provided beneath the base course and it also functions as same as base course. If the sub-grade soil is strong and stiff, then there is no need to sub-base course.

The CMS will likely not only have different modules, but also allow you to select which of these modules you’ll be using in the class. If you’re not going to use a particular module (e.g., if you decide not to use online chat during the course), you should turn that module off so that it doesn’t distract students from the modules you plan to use. (If you decide later to use a module that you’ve turned off, you can turn it on then.)

What is a subbase and base course?

A subbase and base course, or both, provide several good things . The thicker the subbase, the more load the slab can support, so if there are going to be heavy loads on the slab—like trucks or fork lifts—the designer will probably specify a thick subbase.

The sub-grade should be strong enough to take the stresses and also it is important to keep the stresses coming from top layers should be within the limit of sub-grade capacity. To reduce the amount of stress on soil sub-grade, provide thick layers of base course, Sub-base course and surface course.
