1、Designation: C1097 07 (Reapproved 2012)Standard Specification forHydrated Lime for Use in Asphalt Cement or BituminousPavements1This standard is issued under the fixed designation C1097; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisi
2、on, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers high calcium, dolomitic andmagnesian-hydrated lime for use in asphalt cement
3、 or bitumi-nous pavement.NOTE 1Hydrated lime, either calcitic, dolomitic, or magnesian,improves bonding of bitumen and aggregates which reduces susceptibilityto moisture damage, reduces age hardening by chemically stabilizingpolar compounds found in asphalts, and increases initial stiffness ofasphal
4、t mixtures.NOTE 2No attempt is made to present requirements for any by-product lime.1.2 This standard does not purport to address the safetyconcerns associated with its use. It is the responsibility of theuser of this standard to establish appropriate safety and healthpractices and determine the app
