Specifications include, but are not limited to: This specification covers the material requirements and basis of acceptance for abrasives used to treat snow and ice on pavements. The material for abrasives shall be either natural sand or manufactured sand conforming to the requirements of these specifications. All abrasive materials shall consist of hard, durable particles that are free from injurious amounts of clay, loam, or other deleterious substances, or hazardous substances. Abrasive materials meeting the requirements of these specifications shall be accepted unless the Commissioner of Public Works or his designee determines from test results, or service records that (1) the material contains sufficient unsound or deleterious material to be harmful; (2) the particles degrade due to weathering in storage, handling, or while in service such that abrasive is ineffective. Gradation acceptance of abrasive material shall be based upon the condition that the material meets the specification requirements. Acceptance shall be determined at the final point of sampling. Gradation tests shall be performed on samples by sieving in conformance with NYSDOT Materials Bureau Test Methods 703-1P and 703-2P. Moisture content shall be determined by AASHTO Test Method T-255.
