2010 Construction and Material Specifications - Ohio Department of ...

A. Furnish CCS, crushed gravel, crushed ACBFS, and OH slag that meets the
following gradation:
Sieve Size Total Percent Passing
2 inch (50 mm) 100
1 inch (25.0 mm) 70 to 100
3/4 inch (19.0 mm) 50 to 90
No. 4 (4.75 mm) 30 to 60
No. 30 (600 µm) 9 to 33
No. 200 (75 µm) 0 to 15 [1]
[1] Furnish OH slag that has 0 to 10 percent passing
through the No. 200 (75µm) sieve
Furnish gravel used under Item 304 that is crushed from material retained on
the 1/2 inch (12.5 mm) sieve.
B. Furnish CCS, crushed gravel, ACBFS, and OH slag that meets the physical
property requirements:
Percent of wear, Los Angeles test, maximum
(CCS or crushed gravel)
50 %
Loss, sodium sulfate soundness test, maximum 15 %
Percent by weight of fractured pieces
90 %
(one or more faces), minimum
[1] Does not apply to OH slag
[1]
Ensure deleterious substances in CCS, crushed gravel, and ACBFS do not
exceed the following:
Material Type Percent by weight
Shale and shaly material 5.0
Chert, that disintegrates in 5 cycles
of the soundness test
5.0
Except for GS, ensure that the portion of the material passing through the
No. 40 (425 µm) sieve has a maximum liquid limit of 25 and a maximum plasticity
index of 6.
703.1� Materials for Items 410, 411, and 617. Furnish CCS, gravel, ACBFS,
GS, OH slag, BOF slag, EAF slag, RPCC, or RACP for materials.
If RPCC and RACP are used, provide the following information:
1. Specification item that the material was originally constructed
under.
2. The applicable material requirements of the original construction
item.
If the original construction requirements meet or exceed the requirements of this
specification, then the shale, sodium soundness and Los Angeles abrasion test for
RACP and RPCC may be waived. The plastic index and clay requirements are not
required for RACP. Use RPCC that is free of steel.
