[1]
[1] If the MD value is greater than the specification limit conform to
Supplement 1010.
Deleterious substances shall not exceed the following:
Material Type Percent by Weight
Soft pieces 3.0
Coal and lignite 1.0
Clay lumps 0.25
Amount finer than No. 200 (75
µm) sieve
3.0
Pieces having a length greater than
5 times the average thickness
15
Shale and shaly material 2.5
Limonitic concretions 2.5
Alkali 2.5
Chert that disintegrates in 5 cycles
of the soundness test
2.5
C. General Requirements for Fine Aggregate. For fine aggregate calculate
each individual sieve fraction soundness loss and ensure that the fractional size
does not exceed 13.0 percent for all surface courses, intermediate courses and any
asphalt concrete course directly below an open graded friction course.
