ABSTRACT
Heavy test rolling is a widely used quality assurance (QA) technique on earthwork construction projects in Minnesota for the subgrade pavement foundation (Mn/DOT 2000). Test rolling is performed using a pneumatic wheel roller on a compacted surface and the ruts observed beneath the wheels are measured to assess the support conditions. Test rolling has the advantage of providing a continuous visual record; however, it can be difficult and expensive to setup and operate.
