Description / Abstract:
This specification covers two types of lime to be used for
reducing water susceptibility in asphalt mixtures.
Type I—High calcium-hydrated lime containing maximum
magnesium content, calculated as magnesium oxide, of 4 percent by
mass. Compliance with chemical composition requirements shall be
determined by use of T 219 (Note 1).
Type II—Magnesium or dolomitic lime containing
magnesium, calculated as magnesium oxide, greater than 4 but no
more than 36 percent by mass. Compliance with chemical composition
requirements shall be determined by use of ASTM C 25 (Note 2).
The values stated in SI units are to be regarded as the
standard.
Note 1—Magnesium oxide content may be
determined by ASTM C 25.
Note 2—Except that Section 2, "Samples for
Analysis," is excluded.
