1、Designation: C 1097 07Standard Specification forHydrated Lime for Use in Asphalt Cement or BituminousPavements1This standard is issued under the fixed designation C 1097; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers high calcium, dolomitic andmagnesian-hydrated lime for use in asphalt cement or bitumi-nou
3、s pavement.NOTE 1Hydrated lime, either calcitic, dolomitic, or magnesian, im-proves bonding of bitumen and aggregates which reduces susceptibility tomoisture damage, reduces age hardening by chemically stabilizing polarcompounds found in asphalts, and increases initial stiffness of asphaltmixtures.N
4、OTE 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 applicability o

9、cordance with Test Methods C25.5. Physical Requirements5.1 Hydrated lime, either dry or slurry form, shall not havemore than 3.0 % retained on a No. 30 (600 m) sieve and notmore than 30 % retained on a No. 200 (75 m) sieve.NOTE 3Specification D 242 also contains physical specifications forhydrated l
10、ime. Specification D 242 includes four size gradations, ex-pressed as percent passing the sieve. For the two size gradations includedin both Specification D 242 and Specification C 1097, the specificationsare the same.5.2 The particle size of hydrated lime shall be determined inaccordance with Test
11、Methods C110.NOTE 4Some hydrated limes may require a full 30-min wash time.NOTE 5The Test Methods C110method for particle size analysis isrequired instead of the Test Method D 546 method because the because theTest Methods C110method uses a standardized spray nozzle and pressuregauge.6.
