Evaluation of Cement Treated Base Courses.

Evaluation of Cement Treated Base Courses

DOTD began to construct soil cement base courses at lower cement contents of four to six percent with thicker sections of 10 to 12 inches (hereafter referred to as cement treated design). This was based on the philosophy that a thicker section with lower cement content should produce an adequate structural base course and reduce shrinkage c racks.

Guide to Cement-Treated Base (CTB)

ii Abstract: Cement-treated base (CTB) is a mixed-in-place or central-plant-produced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.
