Asphalt Installation
These Asphalt instructions are an addendum to the standard Vector Dynamics concrete instructions. Read and
follow all applicable guidelines in the instructions for Vector, the home, office, classroom or portable building
being installed. Minimum depth of asphalt is 2 inches with a suitable base material compacted under the
asphalt. This system is designed for portable classrooms, offices or other structures using I-beam frames.
NOTE - For Multiple unit sets, always install by unit as they are placed.
1. The asphalt kit is used in combination with the Vector concrete kits 59036 and 59049. The expansion bolts
provided in these kits are not used. Assemble the asphalt bracket as shown in figure 1, using the carriage
bolts and hex nuts provided. The bolt heads will be on the underside (flat) of the Vector pad. The Asphalt
bracket will be positioned between the Vector pad and the tension bracket. Repeat for the second pad.
2. Determine the location of the piers and place assembled pad on asphalt. Center pad under beam with
upturned edge facing the Inside. Place second pad under opposite beam, parallel with first pad. Stack
concrete blocks against up turned lip on pads and finish and wedge pier.
3. Using the asphalt brackets as a guide, drill three 5/8” holes in the asphalt at a 45 degree angle under pier.
Using a sledge hammer or hammer drill, drive rods supplied through the bracket and into the asphalt,
leaving one inch of rod above bracket. Repeat for opposite pad (see figure 2).
4. Measure distance between the two Vector System pads at the base where the Vector pad meets the asphalt.
Cut two ground treated 2x4’s or a 4x4 to length and place between piers as shown. Place a long U-bolt
under the 2x4’s and through the holes in the upturned edge of the Vector Pad. Before securing with the 3/8”
nuts provided, place a 1/2”x1” carriage bolt provided in the square hole in the upturned edge of the Vector
pad. The carriage bolt will be installed with the head of the bolt under the upturned edge with the
threads showing.
5. Attach a strap with swivel strap connector to the 1/2” carriage bolt. Secure with 1/2” nut. Strap should be
of sufficient length to go over the opposite I-beam and down to the tension bracket with 12” -15” extra to
wrap around the slotted bolt. (See figure 2).
6. Insert slotted bolt in tension bracket, and cut strap so there is approx. 12”-15” of strap overlap. Insert in slot
on the bolt so that it is flush with other side of bolt. Tighten strap onto bolt so there are 4-5 turns of strap
around the bolt and repeat for other side.
