STANDARD SPECIFICATIONS

FOR

ACID-RESISTING ASPHALT MASTIC' A.S.T.M Designation: D 223 - 30

These specifications are issued under the fixed designation D 223; the final number indicates the year of original adoption as standard or, in the case of revision, the year of last revision

ISSUED AS TENTATIVE, 1925; ADOPTED, 1930

suitable for use in waterproofing, consisting of mastic cake, asphalt cement and mineral aggregate

(b) The grade of asphalt mastic covered by these specifications

is suitable for waterproofing, tank linings, floors, etc., where dilute mineral acids at temperatures below 100° F (38° C.) are encountered

Properties 2 This asphalt is a mixture of mastic cake, asphalt cement and

Mastic Cake

mineral aggregate, which at a temperature of approximately 205° C ( 400° F ) is sufficiently plastic to be poured into place and compressed with a wooden trowel or equivalent tool into a compact mass

As used for strictly waterproofing purposes the mastic cake, asphalt cement and mineral aggregate are combined under heat and manual stirring in substantially the following proportions by weight:

Mastic Calce 48 per cent Asphalt Cement 5 "

Mineral Aggregate 47

3 (a) The mastic cake shall conform to the following require-ments:

Weight per cake not more than 80 lb Soluble in pure benzol 14 to 18 per cent by weight Insoluble in pure benzol 82 to 86 per cent by weight

(b) The matter soluble in pure benzol shall be asphalt cement, which, after recovery from the mastic cake, shall conform to the requirements of the Tentative Specifications for Asphalt Cement, 25

1 Under the standardization procedure of the Society, these specifications are under the jurisdiction

of the A.S.T.M Committee D-8 on Bituminous Waterproofing and Roofing Materials

Pavements (A.S.T.M Designation: D 163 - 23 T) of the American

Society for Testing Materials.1

(c) The matter insoluble in pure benzol shall be granular mineral

matter which after recovery from the mastic cake shall conform to the

following requirements as to grading

Passing No 200 sieve not less than 25 per cent

Passing No 10 sieve, retained on No 50

sieve not more than 25

Retained on No 10 sieve not more than 1

It shall contain not more than 5 per cent by weight of material

soluble in hydrochloric acid

4 The asphalt cement shall conform to the requirements of the

Tentative Specifications for Asphalt Cement, 25 to 30 Penetration,

for Use in Sheet Asphalt and Asphaltic-Concrete Pavements (A.S.T.M

Designation: D 163 - 23 T) of the American Society for Testing

Materials.1

5 The mineral aggregate shall be gravel or crushed stone and

sand and free from carbonates It shall conform to the following

requirements as to grading:

Passing No 200 sieve none

Passing No 50 sieve, retained on No 200

sieve not more than 25 per cent

Passing No 10 sieve, retained on No 50

sieve not less than 25

Passing No 4 sieve, retained on No 10

sieve not less than 5 0

Retained on No 4 sieve not more than I 0

It shall contain not more than 5 per cent by weight of material

soluble in hydrochloric acid

Asphalt Cement

Mineral Aggregate

6 The properties enumerated in these specifications shall be Method of determined in accordance with the Standard Methods of Testing Testing Bituminous Mastics, Grouts and Like Mixtures (A.S.T.M
