Millions of tons of graded aggregate base (GAB) materials are used in construction of highway base layers in Maryland due to their satisfactory mechanical properties. The fines content of a GAB material is highly variable and is often related to crushing process, stockpiling in the quarry, transportation and during construction at the site.
Also covered are construction and testing of subgrade, pipe installation, roller patterns and reports. Passing both the written and "hands on practical" exams is required to achieve certification.
