IN-PLACE CEMENT STABILIZED BASE RECONSTRUCTION TECHNIQUES INTERIM REPORT: "CONSTRUCTION AND TWO YEAR EVALUATION"

The purpose of this research was to evaluate the effectiveness of soil cement shrinkage crack mitigation techniques. The contents of this report reflect an evaluation of the construction of the test sections and a two-year evaluation of the test sections. This was accomplished through a four-part program that consisted of constructing test sections, laboratory evaluation of materials, structural evaluation of test sections, and crack mapping the soil cement base course and asphaltic concrete pavement. Ten test sections were constructed on LA 89, State Project number 397-04-0004. Each test section was 1,000 ft long. The shrinkage crack mitigation methods that were addressed included cement content, base thicknesses, fibers, interlayer, curing membrane, and curing periods. Since reflective cracks were not observed during the 1.8 year monitoring period, no conclusions can be drawn as to the effectiveness of the different shrinkage crack mitigation methods used. However, based on the cost of construction, the sections may be ranked: 1) cement stabilized and treated base course, 2) cement stabilized base course with crack relief layer or E.A. curing membrane with sand, 3) cement stabilized base course with 0.05% fibers, 4) cement treated base course with 0.05% fibers, 5) cement stabilized base course with 0.1% fibers, and 6) cement treated base course with 0.1% fibers.
