The KEC test road includes 2 lanes of 22 jointed plain concrete pavement (JPCP) sections having variables of slab thickness (250, 300 and 350 mm), subbase materials (lean concrete
, aggregates and asphalt), and subbase thickness (120, 150 and 180 mm) (Jeong 2008).

In the Caltrans project, California-based Yeager Skanska placed 31 panels in two nights on a lean concrete
base and post-tensioned the panels in the longitudinal direction in 124-foot sections.
In many typical applications, a very lean concrete
may be adequate.
After completion of the lower wall system, a lean concrete
footing was placed to support the upper wall on a sandstone subgrade.
