|Significance and Use|
4.1 Earthwork associated with highway construction provides an opportunity for high volume reuse of green foundry sands discarded by the foundry industry. This practice covers methods and recommendations to use of foundry sand as embankment and structural fill.
4.2 This practice describes the unique construction considerations that may apply to foundry sands. The behavior may vary due to specific composition of the material and local conditions.
4.3 The use of foundry sand in embankment and structural fill may be regulated by local, state/provincial/regional, or national/federal regulations. These regulations should be consulted.
1.1 This practice covers methods to use foundry sand as embankment and structural fill.
1.2 This practice includes recommended construction (Section ), compaction control (Section ), and freeze-thaw durability (Section ) practices.
1.3 The engineer should be aware that foundry sand is a by-product of metal casting industries. Various local, state/provincial/regional, or national/federal environmental laws and regulations may apply if foundry sand is used as an alternative embankment or fill material. It is advised that foundry sand users contact appropriate environmental regulators to determine what requirements or limitations may exist.
1.4 This standard primarily applies to green foundry sand and also generally to chemically bonded foundry sand.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This practice offers a set of instructions for performing one or more specific operations. 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 project’s 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.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
