In-Place Cement Stabilized Base Reconstruction Techniques Interim Report: 'Construction and Two Year Evaluation'

摘要

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. The shrinkage crack mitigation methods that were addressed included cement content, base thicknesses, fibers, interlayer, curing membrane, and curing periods.
