Construction Requirements
601.03 Composition (Concrete Mix Design). Conform to Table 601-1. Before batching concrete, submit the proposed concrete proportions for approval on Form FHWA 1606, Minor Portland Cement Concrete Mix Design or other approved form. As a minimum, submit the following at least 30 days before production:
(a) Concrete. Include the following in each mix design submittal: (1) Type and sources of material;
(2) Material certification for material;
(3) Saturated surface dry mass of the fine and coarse aggregate per cubic yard of concrete; (4) Gradation of fine and coarse aggregate;
(5) Mass of mixing water per cubic yard of concrete;
(6) Mass of cement per cubic yard of concrete. Fly ash, ground iron blast-furnace slag, or silica fume (micro-silica) may be substituted for cement according to Table 552-2; (7) Entrained air content of plastic concrete in percent by volume; and (8) Maximum slump of plastic concrete in inches.
(b) Integral colored admixture. If integral color admixture is used, prepare five 2- by 2-foot test panels. Construct the test panels using the proposed mix design. Determine coloring agent batch amounts by weight. Use variable quantities of coloring agent as approved. Provide additional mixing

time according to the manufacturer’s recommendations. Cure the test panels similar to the structure. Transport the panels to an approved location. Provide at least 2 weeks outside exposure. The CO will select the acceptable test panel. Use the same rate of integral color admixture for the item of work. Table 601-1
