3) Clean the Boreholes
Blow the concrete dust from the borehole using oil-free compressed air. Thoroughly brush it
with a 7/8” diameter steel bristle tube brush and then blow it out again. If the borehole is wet,
completely flush it with water while brushing and then blow it clean to remove all water using
oil-free compressed air.
Note:
Use of the Trinity Highway approved vacuum drilling equipment is authorized to replace
the blowing and brushing requirement of Step 3.
4) Apply Approved Adhesive
Fill the borehole 100% full.
Caution:
Fill borehole 100% full so it is even with the pavement surface per
manufacturer’s instructions.
5) Add Nuts to Anchors
Thread the nut on until flush with the end of the stud (Figure 2).
6) Insert Anchors in Boreholes and Wait for Adhesive to Cure
Push the stud down through the part to be anchored and into the borehole.
Warning:
Do not disturb or load the stud until the approved
adhesive material has fully cured (instructions supplied with
the approved adhesive kit).
7) Torque the Nuts
Once the adhesive has fully cured, torque the nut to the
manufacturer’s recommended values.
Anchor Assembly Cautions
1) Steel rebar
If steel rebar is encountered while drilling an anchor bolt borehole, apply one of the following
solutions:
A) Use a rebar drill bit for the
rebar only
and then switch back to the concrete bit to finish
drilling into the underlying concrete until the proper borehole depth is reached.
Caution:
Do not drill through rebar without first obtaining permission to do so
from the project engineer.
B) Drill a new borehole down at an angle past the rebar to the proper depth. Anchor the stud
by completely filling both boreholes with an approved adhesive.
