The pre-wetting of aggregate blended with Organic-Lock prior to placement and compaction is required for optimal installation. Pre-wetting of aggregate can be done at the quarry prior to shipping or in small batches on the job-site by means of a front loader and a water source. The key to install pathway aggregate successfully is based on the moisture content.
Excavate area to depth required so that finish grade can be established as noted on plans. Compaction % of the aggregate will vary from aggregate to aggregate. Install pathway aggregate by preparing mock-up to confirm proper compacted depths. Compact subgrade to 95% modified proctor density.
Place base material to approved depth and compact to 95% modified proctor density. Incorporate crowns or swales, where appropriate, to reduce the chance of sitting water.
Pre-soak base to assist in the bonding of materials and to prevent a layering effect prior to placement of Organic-Lock™ Pathway Aggregate
If pre-wetting of the Organic-Lock™ Pathway Aggregate will be done at the quarry and prior to shipping, skip to step 5 to install pathway aggregate. A front loading tractor and water source can be used to pre-wet the Organic-Lock™ Pathway Aggregate on the job site. This can be done by slowly adding water to the dry pre-blended Organic-Lock™ Pathway Aggregate and turning over the Organic-Lock™ Pathway Aggregate pile until optimum moisture content of between 10-12% is achieved. A thorough blending and consistent moisture content is important to achieve success. If you can easily form a ball of the mixture in your hand, there is too much moisture.
After the proper moisture content has been achieved in the Organic-Lock™ Pathway Aggregate, it must be spread and compacted. The use of a paving machine is highly recommended to install pathway aggregate with larger projects to evenly spread Organic-Lock™ Pathway Aggregate at the specified depth, though a box Gannon™ or similarly equipped tractor/loader can also be used. For small projects spread & grade by hand as per plans. If doing more than 3 inches, separate lifts are required.
Compact the Organic-Lock™ Pathway Aggregate using a 2 ton (or larger) double drum or single static drum roller, or equivalent. Do not use a vibratory plate compactor or vibratory setting on the compactor. Compaction of the Organic-Lock™ Pathway Aggregate will be complete when no further visible roller marks can be seen on the surface.
The surface of the Organic-Lock™ Pathway Aggregate shall be true to elevation and shall not vary by more than 1/4” tested with a straight edge at any location on surfaces. Surfaces shall be crowned at a minimum of 2% and about flush with adjacent materials and/or edge restraint. The surface shall be sloped a minimum of 1% to drain away from structures.
After the Organic-Lock™ Pathway Aggregate has been compacted it is recommended that you apply a light spray to the surface of the Organic-Lock™ Pathway Aggregate to give a clean surface appearance. Apply enough water to just before run-off.
Do not allow any traffic (pedestrian, vehicular, etc.) on the newly installed Organic-Lock™ Pathway Aggregate until fully cured. Light pedestrian traffic can be allowed after the surface has visually dried and feels firm under footing. Organic-Lock™ Pathway Aggregate should be allowed to fully cure before vehicle use is permitted. Curing times will depend on many factors including moisture content at the time of installation, climate, depth of installation, etc.
