1.3.5
Slurry Grout
The additional requirements for production of slurry grout for the Resin
Modified Pavement (RMP) are a concrete batch plant, a ready mix truck, or
portable mixer for grout mixing, and small 1.8 metric ton (2 ton) 2 ton
(maximum) tandem steel wheeled vibratory roller for compaction of RMP.

SAMPLING AND TESTING
1.4.1
Aggregates
1.4.1.1
General
ASTM D 75 shall be used in sampling coarse and fine aggregates. Points of
sampling will be designated by the Contracting Officer. All tests
necessary to determine compliance with the specified requirements shall be
made by the Contractor, using a Corps of Engineers certified Commercial
Laboratory.
1.4.1.2
Sources
Sources of aggregates shall be selected well in advance of the time when
the materials are required in the work. Samples shall be submitted 30 days
before starting production. If a sample of material fails to meet the
specified requirements, the material represented by the sample shall be
replaced, and the cost of testing the replaced sample shall be at the
Contractor's expense. Approval of the source of the aggregate does not
relieve the Contractor of the responsibility to deliver aggregates that
meet the specified requirements.
1.4.2
Bituminous Materials
Samples of bituminous materials shall be obtained in accordance with ASTM D
140. Sources shall be selected well in advance of the time materials will
be required for the work. In addition to the initial qualification testing
of bituminous materials, samples shall be obtained and tested before and
during construction when shipments of bituminous materials are received, or
when necessary to assure that some condition of handling or storage has not
been detrimental to the bituminous material.
1.5
DELIVERY, STORAGE, AND HANDLING OF MATERIALS
1.5.1
Mineral Aggregates
Mineral aggregates shall be delivered to the site of the bituminous mixing
plant and stockpiled in such a manner as to preclude segregation or
contamination with objectionable material.
1.5.2
Bituminous Materials
Bituminous materials shall be maintained below a temperature of 150 degrees
C 300 degrees F during storage and shall not be heated by the application
