| Abstract | A study of chemical stabilization of soils began in 1954 with a program enlisting the aid of chemical industry in the search for effective chemicals. Nineteen firms signed a letter of agreement, and others cooperated on an informal basis. Federal participation consisted mainly of consultation, instruction, development of suitable laboratory evaluation test procedures, and review of test results furnished by cooperators. A number of chemicals, notably phosphoric acid, PDC, Terbec, lignins and quaternary amines, were proposed and evaluated in laboratory and field tests. Many others were given limited examination and laboratory testing. At about 1965, industry's interest shifted largely toward chemicals affecting compaction and moisture-density relationships of soils. Several proprietary compaction aids were evaluated by laboratory tests and one was the subject of field testing. A report on laboratory evaluation of two compaction aids has been prepared. No single chemical or combination of chemicals has been found acceptably effective or economical as a major soil stabilizer. However, further work with phosphoric acid and phosphates may make use of some of these substances possible. Prospects are promising for chemicals to improve moisture-density relationships and to supplement or enhance the effects of the major stabilizers, lime and Portland cement. |
