Scope.
1. These specifications cover t to H-in. and i to 2}-in. size
graveL, either of which sizes is suitable for use in the construction of
a bituminou·s concrete base prepared by the mixing method and upon
which may be placed any type of surface course.
General
2. The gravel shall consist of bard, sound,' tough, durable stone
Charac­
particles, either crushed or uncrushed, and shall be free from injurious
teristics .
amounts of adherent coatings and soft, thin, elongated or laminated
pieces, or other deleterious substances.
Abrasion.
3. Gravel shall show a satisfactory resistance to abrasion as
measured by an acceptable abrasion test for gravel.
NOTE.-No test limits for abrasion are specified due to the status of knowledge
concerning ~ltitable specification limits for this test . Many engineers feel that the
q uality of gravel may be indicated by the results of an abrasion test, and accordingly
the Tentat ive Method of Test for Abrasion of Gravel (A.S.T.M. Designation:
D 289 - 28 T) of the American Society for Testing Materials~ is recommended.
Deleterious
4. The amount of deleterious substances shall not exceed the
Subs tances .
