(A) Granular subbase shall be placed in accordance with IDOT Specification § 2111.03 to meet the requirements set forth for secondary projects. Compact subbase material to 95% of maximum consolidation (standard proctor density). Maximum consolidation may be determined in the field on an initial trial section using nuclear testing equipment, under the direction of the engineer.
(B) Subbase material placed on the prepared subgrade shall have a uniform moisture content throughout the material to produce the required density, together with stability.
(C) The subbase shall be constructed so that the finished subbase conforms to the designed profile and cross section to the extent that it is not higher than the designed elevation and at no point is lower than 0.05 foot below this elevation.
