Surface Preparation

Written By: Michael Wandersee/Revised Ann Erin Mercer for 2021 projects Date: 2021

6 | P a g e

General: Immediately before placing aggregate materials, remove loose and deleterious material from substrate surfaces. Ensure that prepared subgrade is ready to receive surfacing Stockpiled material shall be free of plants, lumps of gravel, concrete or chip‐seal material, or any structure that causes the material to cause spreading issues

Placement Place and compact surface material in layers to required elevations to avoid ponding and poor drainage

Soil Moisture Control Uniformly moisten or aerate subgrade and each subsequent fill or backfill soil layer before compaction to within 2 percent of optimum moisture content

a. Do not place gravel material on surfaces that are muddy, frozen, or contain frost or ice

b. Remove and replace, or scarify and air dry, otherwise satisfactory gravel that exceeds optimum moisture content by 2 percent and is too wet to compact to specified dry unit weight

Compaction Place aggregate materials in layers not more than 8 inches in loose depth for material compacted by heavy compaction equipment, and not more than 4 inches in loose depth for material compacted by hand‐operated tampers and/or roller with no more less than 250 pounds per inch of roller width Place aggregate materials evenly on all sides of structures to required elevations, and uniformly along the full length of each structure Compact each layer of backfill or fill soil material at 95 percent

Grading General: Uniformly grade areas to a smooth surface, free of irregular surface changes.

Comply with compaction requirements and grade to cross sections, lines, and elevations indicated Site Rough Grading: Slope grades to direct water away from buildings and to prevent ponding
