BEHAVIOR OF STABILIZED SOILS UNDER REPEATED LOADING;REPORT 6, A SUMMARY REPORT WITH A SUGGESTED STRUCTURAL PAVEMENT DESIGN PROCEDURE

摘要

Results of previous investigations completed in this research are briefly summarized. This summary as well as the results of other investigations completed during the period of this investigation, also summarized where approporiate, form the basis for the design procedure recommended herein. The design procedure is applicable to a two layer system - a cement stabilized layer resting on a subgrade. Stresses and deformations are estimated using layered elastic theory. Essentially the procedure consists of two phases, the first being the selection of a thickness adequate to prevent fatigue in the cement-stabilized layer and the second a check to insure that the combination of load and thermal stresses will not crack the stabilized layer. The procedure also recognizes the fact that cement stabilized bases will crack due to shrinkage stresses shortly after construction.
