Pavement Geotechnical Design

Pavement design determines the appropriate thickness of asphalt, base, and subbase layers to support the expected traffic loading without premature failure — based on the subgrade soil strength, traffic volume, and design life. Apex Grid geotechnical engineers provide pavement subgrade evaluation and pavement section design for commercial parking lots, driveways, and access roads.
