scope:

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 (see Note 1).

Note 1-Magnesium oxide content may be determined by ASTM C25.

Type II-Magnesium or dolomitic lime containing magnesium, calculated as magnesium oxide, greater than 4 percent but no more than 36 percent by mass. Compliance with chemical composition requirements shall be determined by use of ASTM C25 (see Note 2).

Note 2-Except that Section 2, "Samples for Analysis," is excluded.

The values stated in SI units are to be regarded as the standard.
