B. Installation of Class 2 Base: o Install Class 2 base material to a specified depth, ensuring proper gradation and compaction. o Perform moisture conditioning and compaction to achieve 95% relative compaction according to ASTM D1557. o Ensure proper drainage is maintained in the installation of the base material.
