703.���
Perform expansion testing according to Pennsylvania Department of
Transportation PTM No. 130, the ODOT equivalent to this test or expansion
testing acceptable to the Department.
Ensure that the producer hires an independent AASHTO accredited and
Department approved laboratory to perform at least half of the expansion testing.
At the producer’s option, up to half of the required expansion testing may be
performed by the producer’s laboratory. The Laboratory will observe the
expansion testing and approve each independent and producer laboratory.
Perform expansion testing for every 2500 tons (2300 metric tons) or fraction
thereof of the material supplied.
The maximum allowable total expansion for each test is less than 0.50
percent. If any one test fails in the stockpile, the Department will reject the entire
stockpile.
When sampling for expansion, ensure that the producer notifies the
Department at least 48 hours before the sampling. The Department will verify that
the sample came from the correct stockpile and take independent split samples, if
required.
Submit the expansion test data and a suitably presented summary of the
expansion test data to the Department for approval. The Department reserves the
right to perform independent testing to verify the laboratory results at any time.
The Department expansion test data takes precedence over the producer or
independent laboratory expansion testing results in the event of a conflict. The
Department will make the final determination on all conflicting data.
If the material fails the expansion testing, then stockpile the material for a
minimum of 2 additional months from the date of last sampling and retest for
expansion. Only materials that pass the expansion test are approved for use.
703.1� Suitable Materials for Embankment Construction. Natural soil,
natural granular material, granular material types, slag material, brick, shale, rock,
random material, RACP, RPCC, or PCS as further defined below are suitable for
use in embankment construction. The Engineer will submit samples of soils not
identified from the plan subsurface investigation, from borrow sources or materials
appearing questionable in the field.
Furnish ACBFS according to Supplement 1027.
Furnish RPCC with the reinforcing steel cut to a maximum length of 1 inch (25
mm) outside the pieces.
Ensure that pieces of RACP do not exceed 4 inches (100 mm) in the largest
dimension.
Furnish OH, EAF, and BOF slag that are blended and according to 703.14.
Furnish OH slag, EAF slag, BOF slag, RPCC, and RACP that are completely
blended with natural soil or natural granular material as follows:
1. When using RACP, OH slag, or RPCC, make at least 30 percent of the blend
natural soil or natural granular materials.
