Prevent accidents in a construction zone by reducing speed
This rumble strip offers you a unique design that creates an audible signal alerting drivers to reduce speed. It features 10 noise steps, a short "landing" and a 90°, 1/2" drop-off at its trailing edge. This edge makes it possible to remove the rumble strips at the completion of a job by simply running a blade into it.
Strong But Flexible
These rumble strips are molded from a flexible, high-impact plastic that is so strong it will not shatter or break in hot or cold weather, even under conditions of heavy truck traffic.
Easily Installed
Apply with recommended flexible bituminous or epoxy.
Epoxy the strips down the entire length. Epoxy should fill channels and come up through weep holes. Trowel excess epoxy in fillet on leading and trailing edges.
Recommended applications:
- Temporary construction zones
- Permanent installations - in non-plowable states, strips can be used a reduction of speed is needed.
Recommended Use (see diagram image above) is to place a series of six rumble strips across the traffic lanes parallel to the chalk lines so they make one long strip. Then, additional strips (of six rumble strips each) are placed next to each other to form a section that has a total of 36 rumble strips. These sections are placed at 5' centers in 45 mph speed zones and 200' in advance of various constructions zone warning signs.
In the test evaluation, vehicle speeds were checked in three ways:
- Using standard construction signs
- Adding 35 mph regulatory signs
- Adding Astro Optics rumble strips
The test showed that by adding the rumble strips, average vehicle speed was reduced more than 8 mph as compared to the use of standard construction signs and more than 4 1/2 mph as compared to using both construction signs and 35 mph regulatory signs.
