If a geotechnical report addresses sulfate testing of
known to have experienced D-cracking or alkali silica
reaction, this section should be edited accordingly.
If this information is not known, require the
Contractor to obtain the information and address the
issue in the Design Analysis if concrete pavement
demolition is in the project.
Existing Portland cement concrete (PCC) pavement may be crushed
and reused as material for subbase, aggregate base course,
stabilized layers, and bituminous mixtures provided the RCA and
the native soils and groundwater meet all of the following
Crushed material must meet specified gradation requirements
for the intended use.
Crushed material must meet the quality requirements for the
requirements for sulfate soundness, abrasion loss, flat
and/or elongated particles and fractured bases.
Subgrade soils must be tested in accordance with CRD-C 403,
Method for Determination of Sulfate Ion in Soils and Water,
to determine the presence of sulfates. Subgrade soils must
