CHAPTER  18 SOIL STABILIZATION Soil stabilization may be broadly defined as the alteration  or  preservation  of  one  or  more  soil  properties to   improve   the   engineering   characteristics   and performance  of  a  soil.  This  chapter  is  intended  to provide you with a brief overview of soil stabilization in terms of (1) stabilization methods, (2) the types and selection of various chemical stabilizers used in soil stabilization and (3) general guidance and information relative to the design and testing of soil-cement and soil-bituminous mixtures. For a thorough understanding of the subject of soil stabilization, you should combine the study of this chapter with the study of the various references  cited  within  the  chapter. METHODS  OF  STABILIZATION The  two  general  methods  of  stabilization  are mechanical   and   additive.   The   effectiveness   of stabilization   depends   upon   the   ability   to   obtain uniformity  in  blending  the  various  materials.  Mixing  in a  stationary  or  traveling  plant  is  preferred;  however, other means of mixing, such as scarifies, plows, disks, graders,  and  rotary  mixers,  have  been  satisfactory. The method of soil stabilization is determined by the  amount  of  stabilizing  required  and  the  conditions encountered  on  the  project.  An  accurate  soil  description and classification is essential to the selection of the correct  materials  and  procedures.  Table  18-1  lists  the Table  18-1.—Stabilization  Methods  Most  Suitable  for  Specific  Applications 18-1
