and ASTM C 311. If the pozzolan consists of fly ash, obtain approval from the Materials Program prior to its use. Use portland cement in accordance with Subsection 801.1, Portland Cement.
801.4Admixtures
1 Use concrete admixtures in accordance with the following:
1.
Air-Entraining Admixtures. Meet the requirements of AASHTO M 154 (ASTM C 260).
2.
Water-Reducing, Accelerating, or Set-Retarding Hydration Stabilizers, and Shrinkage-Reducing Admixtures. Meet the requirements of AASHTO M 194 (ASTM C 494). Do not use admixtures containing calcium chloride.
3.
Silica Fume Admixture. Use a dry compacted form in accordance with AASHTO M 307 (ASTM C 1240), including Table 3.
801.5Synthetic Fibers
1 Use 100 percent polypropylene collated, fibrillated fibers with the physical properties
shown in Table 801.5-1, Synthetic Fiber Properties.
Property Specific Gravity, min. Modulus of Elasticity Tensile Strength Length
Table 801.5-1 Synthetic Fiber Properties Value 0.91 500,000 to 700,000 psi [3450 to 4830 MPa] 70,000 to 110,000 psi [485 to 760 MPa] Maximum ( 1 in [25 mm])
Ensure the polypropylene fibers are specifically manufactured from virgin polypropylene, containing no reprocessed olefin materials. Ensure product documentation includes certification from the original manufacturer of the fibers.
801.6Slag Cement
1 Use Grade 100 or Grade 120 slag cement with a maximum Aluminum Oxide content of
11.0% in accordance with ASTM C 989. Before use, obtain approval of the source from the Materials Program; approval will be based on test results provided by the slag cement supplier using the following sampling frequency: Monthly ASTM C 989 results for composite samples for a six month period. 2 A list of approved sources of slag cement is available from the Materials Program.

802.2Evaporation Retardant
1 For evaporation
retardant provide a thin monomolecular film producing compound designed to reduce the surface evaporation rate. Preapprove evaporation retardants through the Materials Program.

Aggregate
803.1General
1 Before producing aggregate, remove vegetation, topsoil, and overburden from the pit
area to be used. Ensure that the materials are free of deleterious substances and do not contain an excess of thin, flat, elongated, soft, or disintegrated pieces. Ensure that aggregates for plant mix base, pavement, wearing course, microsurfacing, and chip seal do not have adherent films of clay or other matter that could prevent thorough coating with asphalt. 2 When crushed aggregate is specified for subbases, bases, or plant mix pavements, crush
boulders with diameters up to 30 in [750 mm] and distribute uniformly throughout the material. 3 The
department defines a gradation requirement as the percentage of material by weight [mass] that passes through a laboratory sieve with square openings and of a size or designation in accordance with AASHTO M 92 (ASTM E 11). The department defines “coarse aggregate” as material retained on a No. 4 [4.75 mm] sieve and “fine aggregate” as material that passes through a No. 4 [4.75 mm] sieve.
For quarried aggregate, material rejected during primary crushing may be used in subbase or crushed base, provided the combined material meets applicable specifications; dispose of other rejected material as directed by the engineer. If quarrying from an available or mandatory source listed in the contract, crush the quarried material with a primary crusher to 4 in [100 mm] or less, without allowing more than 5 percent to pass through a 1-inch [25 mm] sieve.
803.2Aggregate for Concrete
803.2.1 Fine Aggregate 1 Use washed fine aggregate in accordance with AASHTO M 6 but not exceeding the limits
