Compact the aggregate using one of the following methods as specified:

(a) Compaction A. Operating spreading and hauling equipment over the full width of the travelway.

(b) Compaction B. Operate rollers and compact as specified in Subsection 204.11(a)(4)(a).

(c) Compaction C. Moisten or dry the aggregate to a uniform moisture content between 5 and 7 percent based on total dry weight of the mixture. Operate rollers and compact as specified in Subsection 204.11(a)(4)(a).

(e) Compaction E. Compact to a density of at least 95.0 percent of the maximum density, as determined by AASHTO T 180, method C or D.

For all compaction methods, blade the surface of each layer during the compaction operations to remove irregularities and produce a smooth, even surface. When a density requirement is specified, determine the in place density and moisture content according to AASHTO T 310 or other approved test procedures.

301.06 Surface Tolerance. Remove irregularities and shape to a uniform surface. Ensure that the thickness and width of the compacted aggregate conform to the dimensions SHOWN ON THE DRAWINGS, and that measurements on the compacted aggregate meet the following criteria:

Construction Requirements

625.03 General. Apply turf establishment to prepared ground or any disturbed area between April 15 and October 31. Apply turf establishment to the areas shown on the plans or worklists within 30 days after completion of ground disturbing activities.

Seeded areas damaged by construction activities shall be reseeded. Do not seed during windy weather or when the ground is excessively wet, frozen, or snow covered.

Assure that all seed and mulch used in the work conforms to the weed free requirements of Section 713.

625.04 Preparing Seedbed. Ensure that the surface soil is in a roughened condition favorable for germination and growth.

625.05 Watering. Moisten seeding areas before seeding and maintain the moisture until turf is established or until final acceptance.

625.06 Fertilizing. Apply fertilizer by the following methods:

(a) Dry Method. Apply the fertilizer with approved mechanical equipment. Hand operated methods are satisfactory on areas inaccessible to mechanical equipment.

(b) Hydraulic Method. Use hydraulic-type equipment capable of providing a uniform application using water as the carrying agent. Add fertilizer to the slurry and mix before adding seed. Add the tracer material when designated by the CO.

Apply fertilizer at the rate of 100 pounds per acre. Follow manufacture’s recommendation for product and site conditions. Use an organic (bio-based), slow release fertilizer meeting the following chemical analysis:
