Rapid Method of Construction Control for Embankments of Cohesive Soil

摘要

The Monograph presents a method of evaluating quickly and accurately the compaction of cohesive soils used in construction of earth embankments. In contrast to the time-consuming methods previously used, the technique presented in this monograph makes it possible to determine the essential values of moisture and density within an hour after the field measurements are made on an embankment. With this method, effective compaction control can be carried out expeditiously and economically. In brief, by use of the rapid method, the degree of compaction of the fill is precisely determined by comparing the density of the embankment with a laboratory standard. This is done by a simple mathematical device. Also, by this method, moisture control to a satisfactory degree of precision is achieved. The theory of the rapid method is described in this monograph, as well as step-by-step procedures and results of experiences to date with the method. Appendixes to the text contain supplementary information and mathematical derivations.
