Abstract
This specification covers testing and property requirements of two types and two grades of sodium chloride obtained from natural deposits (rock salt) or produced by man (evaporated, solar, and others), intended for use as a deicer and for road construction or maintenance purposes. Type I is used primarily as a pavement deicer or in aggregate stabilization. This type is further subdivided into Grade 1 (standard grading) and Grade 2 (special grading). Type II, is used in aggregate stabilization or for purposes other than deicing. The sodium chloride shall be sampled, tested, and conform to chemical and physical requirements discussed herein.
Scope
