PAVE EDGE® INSTALLATION
Unsuitable, unstable or unconsolidated material shall be excavated to reach solid sub-grade.
Depth of Base Course aggregate is dependent upon CBR (California Bearing Ratio) of sub-grade, Type of aggregate for base, Quality of compaction, Expected traffic loads, Moisture expectations, Freeze-Thaw, and other factors. If pavement is to be used in commercial or industrial project the base design should be fully engineered by competent professionals.
For most projects the following is a recommended guideline:
- Pedestrian exclusively 4"-6" base
- Light Vehicular 6"-12" base
- Moderate Vehicular Occasional Heavy loading 8"-18" base
Base course aggregate shall be 5/8" minus crushed aggregate and consist of sound, durable particles, free from clay, organic material or other deleterious matter, with 100 percent passing a 3/4" sieve size and a maximum of 5 percent passing a #200 sieve.
Compaction of base course material should be in maximum 4" lifts and compacted with suitable vibratory compaction equipment to reach 95 percent + Modified Proctor density of ASTM 1557. Moisture content of base material should be kept at optimum during compaction.
Base preparation should extend beyond the edge of the pavement to allow for a shoulder to support the base. The following is a recommended guideline:
- Walkways 4"-8"
- Driveways 6"-10"
- Commercial/Heavy 18"-36"
PAVE EDGE® INSTALLATION:
- Layout - Many times it is important to lay out the perimeter or boundaries first. PAVE EDGE® RIGID helps you stay on your chalk or string lines as you spike it in. PAVE EDGE® FLEXIBLE helps you lay out precise curves and radiuses, providing just the right amount of resistance to help you lay out gradual, flowing curves. Place PAVE EDGE® on top of uniformly compacted graded gravel base per pavement design, and spike through edging into the compacted base using 10" x 3/8" diameter steel spikes.
- Curves and Radiuses - Provide PAVE EDGE® FLEXIBLE edging for all radii. In the event PAVE EDGE® FLEXIBLE is not on hand, use PAVE EDGE® RIGID edging by cutting the backside with a hack saw; a straight cut for outside radii and a wedge shaped cut for inside radii. The more frequent the cuts, the tighter the curve that can be made. When using PAVE EDGE® INDUSTRIAL it will be necessary to relief cut both the front and back side of the edging in order to make it flex adequately.
- Joining Sections - Insert the provided connector pipe into the most forward cavity of the edging. Having started the connector in one section, use a twisting motion to slide two sections together.
- Spiking - Pound in spikes only part way every 4 ft. (to accommodate edging adjustment) using 10" x 3/8" diameter steel spikes. After final edging placement, finish setting spikes so that the heads of spikes are tight to the edging material,
PAVE EDGE® FLEXIBLE edging, one spike must be used in every support section
PAVE EDGE® RIGID use one spike every 3 feet on patios and sidewalks, 2' for driveways and every 12" for extreme high traffic areas.
PAVE EDGE® INDUSTRIAL is spiked every 6" alternating each side of the edging into the pre-drilled holes.
PAVE EDGE® is designed to be installed on the compacted base, NOT on top of the bedding sand! It is best to use 1” of coarse washed sand for your bedding course.
PAVE EDGE® can be installed before or after pavers are laid. If installing later, first pull away the excess bedding sand. Using a trowel or shovel cut straight down the side of the pavers to the base and pull back the sand. Do not scrape up base material. Place PAVE EDGE® flat on the base then push the frost heave lip under both sand and pavers. If any small gap remains, sweep sand into gap before tampering.
Pavers and edge restraints on a residential job will receive their heaviest load at the time of installation. If your edge restraint shifts at that time it will likely continue to move and paver interlock will begin to fail.
