1.1 This guide covers procedures for the design of stabilization of soil and soil-like materials using self-cementing coal fly ash for roadway applications, treatment of expansive subgrade or organic subgrade, and limiting settlement of fills below buildings. The coal fly ash covered in this method includes self-cementing fly ashes described in Specification D5239.

1.2 The testing and engineering practices for self-cementing coal fly ash are similar to generally accepted practices for soil stabilization with fly ash and other pozzolans that require lime.

1.3 The test methods in this guide are applicable to the characterization of mechanical properties of in situ mixed self-cementing fly ash stabilized materials. There are other related fly ash stabilization standards. Practice D5239 can be used to characterize the general types of fly ash for use in soil stabilization. Specification C593 can be used to evaluate the performance of fly ash and other pozzolans that require lime soil stabilization. Guide E2277 can be used to characterize properties of fly ash and bottom ash in structural fills and related design and construction considerations.

1.4 The standard units are the SI units, unless other units are specified.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.6 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a projects many unique aspects. The word Standard in the title of this document means only that the document has been approved through the ASTM consensus process.
