Description
313.01This work consists of providing and placing an aggregate, topsoil, and seed mixture on a prepared shoulder or other surface.
Material
313.02Conform to the following Subsections: Aggregate for aggregate -topsoil course 703.13 Seed 713.04 Topsoil 713.01 Water for construction 725.01(c)
Construction Requirements
313.03Preparing Surface. Complete th e adjoining pavement before placing an aggregate -topsoil course on the shoulder. Scarify the area where the mixture is to be placed to a depth of 3 inches. Reduce clods and sod to a maximum size of 4 inches.
313.04Mixing, Placing, and Compacting. Provide a mixture of 50±10 percent aggregate and 50±10 percent topsoil by volume with sufficient water for compaction. Mix the components into a uniform mixture. Spread the mixture on the prepared surface in a uniform lift. Shape the mixture to the required line, grade, and cross -section. Remove clods and stones greater than 2 inches in diameter. Before compaction, dry seed the mixture surface at a rate of 75 pounds per acre according to Section 625. Uniformly compact the mixture to ensure it does not exhibit heaving, pumping, rutting, or shearing. After compaction, dry seed the surface again at a rate of 75 pounds per acre. Before opening the roadway to traffic, clean the roadway surface of excess aggregate, topsoil, and seed material.
313.05Acceptance. Aggregate for aggregate -topsoil will be evaluated under Subsections 106.02 and 106.03. Seed and topsoil will be evaluated under Subsections 106.02 and 106.03. Construction of aggregate-topsoil course will be evaluated under Subsection 106.02.
