AsphaltEdge
Restraint Goal
To securely retain the paver and setting course while
providing a long-term, visually aesthetic and easily maintainable
edge.
*Application
Overview:
-
AsphaltEdge is anchored into the asphalt base. Anchoring choice
(see below) will be dependent on age, hardness, thickness and
composition of asphalt base (binder) course.
- The
setting course is spread over the asphalt base and serves as a
leveling course filling in the unlevel portions of the asphalt
base.
- Pavers
are laid on setting course with a thin layer of fines then spread
over the paver surface.
- The
entire installation is then vibra-pacted into place.
- Semi-compact
backfill material adjacent to the completed paver installation
providing additional support.
*Intended
as an overview only, please refer to specifier/ manufacturer technical
specifications.
Application
Note:
We recommend AsphaltEdge for this paver application. AsphaltEdge’s
wider base (2-1/4” or 3” depending on AE product) offers
a wider surface to mechanically anchor the restraint down to the
asphalt.
Anchoring
Note - In all cases, it is desirable to use mechanical
vs. manual anchoring. Composition, age, hardness, thickness and
regional asphalt variables will guide anchoring method. The following
are guidelines:
-
Anchor at ends of each section in addition to guidelines indicated
below.
-
New, softer or thinner asphalt - 3/8” x 10” spiral
steel spikes (12” on center) typical.
- Older,
harder, thicker asphalt - Hilti DX A41 Fully Automatic Powder
Actuated Tool with nail is desirable where sufficient hold can
be obtained. 1-1/2” to 2-_” nail (12”on center)
with appropriate charge is recommended. Contact Hilti customer
service 800.879.8000 for details.
AsphaltEdge Product:
Typically AsphaltEdge 2-_”
As a rule, it is desirable to cover a minimum of 1/3 to _ of the
paver height.
(Typical paver - 6cm = 2-3/8” / less common 10cm paver = 4”)
Formula – 1/3 to _ paver height + setting course depth (minus
_” for compaction) = minimum restraint height.
Variables
- Height
of the paver - Typical paver - 6cm = 2-3/8” / less common
10cm paver = 4”
-
The depth amount of paver (side wall) coverage desired by specifier
or installer.
-
Amount of setting course compaction – typically _”.
