S.K.T. Installation Checklist (Return To SKT Home)
NOTE: This is a generic list of "things to look for" when installing the SKT terminal system. Please refer to the latest copy of the installation manual for complete information.
The rail height
is in accordance with the plans (generally 27-3/4" above the edge of the shoulder).
The foundation
tubes do not protrude more than 4" above the ground line (measured by the AASHTO
5' cord method). Site grading may be necessary to meet this requirement.
The bolts at the
top of the foundation tubes are not over-tightened, deforming the walls of the
tubes.
The guide chute
of the impact head is parallel to the top of the rail and the impact head does
not encroach on the shoulder (a 50:1 taper is permitted to eliminate the potential
for encroachment).
The two lag screws
holding the impact head to post 1 are snug.
The 8" x 8" bearing
plate at post 1 is correctly positioned with the 5" dimension up & the 3"
dimension down. The anchor cable is taut and correctly installed. A
nail has been placed over the bearing plate to prevent rotation.
The cable anchor
bolts are properly attached to the W-beam guardrail and the cable anchor box
is fully seated on the should portion of the cable anchor bolts.
Posts installed
in foundation tubes have the 2-1/2" breakaway hole located parallel to the roadway
with the bottom of the hole at the top of the tube.
CRT posts have
two 3-1/2" breakaway holes (checked prior to installation) located parallel
to the roadway with the center of the top hole located at the ground line.
If the posts were
augered, be sure the backfill material around the posts is compacted.
No washers are used on the face of the rail except at the cable
anchor bracket bolts.
