The type of soil present in the subgrade must be evaluated. Different types of soil can pose different issues that must be addressed. For example, fine-grained sand tends to have less load-bearing capacity, while soil with a high clay content can be prone to excessive shrinking and swelling as the moisture content changes.
After the subgrade is leveled and compacted, the base can be installed. The thickness of the base depends in large part on the type of soil present in the subgrade. If the subgrade has a low support value, the base will need to be thicker to ensure that the completed pavement will perform as expected.
Once the base is prepared, the contractor can install the concrete. Forms will be constructed, and in most cases, reinforcing steel bars will be placed in the forms. The concrete is then poured and smoothed.
