This specification covers high calcium, dolomitic and magnesian-hydrated lime for use in asphalt cement or bituminous pavements. Hydrated lime, either dry or slurry form, shall conform to the chemical composition requirements for calcium and magnesium oxides, carbon dioxide, unhydrated calcium and magnesium oxides, and free moisture of dry hydrates as shall be determined by chemical analysis. The particle size of hydrated lime shall also be determined using a standardized spray nozzle and pressure gauge.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers high calcium, dolomitic and magnesian-hydrated lime for use in asphalt cement or bituminous paving mixtures.
Note 1: Hydrated lime, either calcitic, dolomitic, or magnesian, improves bonding of bitumen and aggregates which reduces susceptibility to moisture damage, reduces age hardening by chemically stabilizing polar compounds found in asphalts, and increases initial stiffness of asphalt mixtures.
Note 2: No attempt is made to present requirements for any by-product lime.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard
1.3 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.
1.4 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.
