Quazite Applications
Traffic Signal Bases Reduce Installation Costs
The Beaumont District of the Texas Department of Transportation chose
QUAZITEŽ traffic signal bases when the District had a project requiring new and
retrofit installations of traffic control cabinets. The QUAZITEŽ traffic signal bases were
less expensive to install, could be quickly installed by District employees, could be
relocated and could reduce potential injury and/or liability if struck by a vehicle.

The District had previously poured concrete in place at an approximate cost of
$1,000 for each traffic signal foundation. The installation process using concrete
could take up to one week or more depending on weather and involved having to
schedule around other work crews. The cost of the QUAZITEŽ base was $500
(1/2 the cost of the alternative method) and installation time was reduced
to one-half day.

QUAZITEŽ traffic signal bases are constructed of reinforced polymer concrete
manufactured in molded structural shapes. The inner surface consists of a
heavy gel coat of polyester resin to provide a smooth non-abrasive working surface.
This surface is backed by a double layer of heavy-weave fiberglass.
As a result of this construction, QUAZITEŽ traffic signal bases combine
high strength and rigidity with minimal weight.

The District also had many retrofit applications in urban areas where it would have been very difficult to pour concrete. The QuaziteŽ base was easy to install over existing conduit runs and old bases and could be easily bolted to the sidewalk. The need to block traffic during the retrofit project was dramatically reduced.
The potential liability of a massive poured in place foundation in a traffic right of way area was a major concern. The QUAZITEŽ base weighs only a fraction of the concrete and will cause less damage to vehicle and driver in the event of an accident. According to James Strawther, Traffic Signal Manager of the Beaumont District, "This QUAZITEŽ base probably saved some lives when a tractor trailer ran into the side of it. The QUAZITEŽ construction allows the side impact to be lessened and so prevented a serious injury which would have resulted from the traditional structure."
Installation Information
Greeley installation
Greg,
I took part this past Wednesday in a conversion of a Greeley maintained CDOT 332 application over to a City of Greeley 332SD installation at 65th and the bypass. Total resources included Mike Comstock and Joe from Greeley (2 men total), a small back hoe / bucket, 1 ton (small) City truck with dump capability, Quazite PH pad, less than a yard of crushed rock and two 5 gal buckets of 2-3" dia rock, one shovel and one wide broom.
Total time on the site was approx. 2 hours and 30 minutes, but included replacement of an existing Armorcast box (with 2 sides having caved in), digging of a 30" deep x 5' trench, and installation of 3 pvc conduits and 6 sweeps over to the pad location. The pad site had already been marked with flags and spray paint. Actual time to dig/scrape and compact the area for the pad was 12 minutes. This would have been work done regardless of whether the project was poured in place or used our pad. In the first case, workers would now start building a form, calling in a cement truck and getting ready to wait for two days while the pour cured.
Using the Quazite pad from this point and materials on hand, the elapsed time starting from removal of the pad from the truck, dumping/scooping the base composition, leveling, pad placement, releveling and having the job complete and ready for the control cabinet installation totaled 31 minutes. With digging and prep of the pad site before placement of the gravel, Mike and Joe still had all facets of a Quazite project done by themselves in less than 45 minutes. Equally important would be an installation that was mag chloride and chemical proof, capable of standing up to any requirements related to weather, maintenance, weight loading requirements of heavier cabinets and batteries, and essentially rodent and varmint proof. I believe we were all satisfied with the installation proceedures and time requirements. Pad weight was not a factor, given the equipment required at the site in any case. My thanks to Mike and Joe for letting me tag along and document an additional installation, adding to Mark's pictures in Douglas County.
