Foundations and Drainage of Highways
This paper is based on field studies made by the writer in the Pacific Northwest during 1920 and 1921. The object of the studies was the development of simple and practical field tests and methods of identifying good, fair, and bad sub—grade soils. As a result of the investigation the volumetric shrinkage of the soil was concluded to be the fundamental adverse factor. For measuring this, a linear shrinkage test was devised, as the displacement of pavements seemed to be caused principally by the distortion of the sub—grade in one direction—vertically. The procedure for the field moisture equivalent test was devised to prepare soils for the linear shrinkage test by wetting them with comparable quantities of water; but later it came to have a value of its own.
