Industrial & Custom Coatings - Fabick Joint Seal

BEST PRACTICE – Use of Fabick product (FJS) to install vehicle sensors.

Brief Description:

This product improves the installation process for traffic sensors.  Previously, products took three hours to ten hours (depending on temperature) to harden to the point where the lane could be reopened to traffic.  This product is tack free in three minutes and the lane can be reopened to traffic in less than an hour.  This reduces the cost of lane closures, reduces congestion, and travel time.  It also enhances safety for workers because they are on the road for shorter period of time, and it increases safety for the traveling public because the disruption of the normal traffic flow is minimized.  The product is non-toxic and non-hazardous.  The manufacturer is located in Madison.

A concrete saw is used to cut a slot of the appropriate size in the pavement.  In blacktop pavement, a needle scalar is used to roughen up the bottom edge of the slot’s sides in order to get the product to adhere more firmly.  The product comes in two parts that are mixed as they are forced through the nozzle of a dual component applicator. 

Potential application (s):

It is currently used to install piezoelectric axle sensors; it may also be useful for installing weigh-in-motion frames and inductance loops. A similar product has bee tested on bridge joints.

Primary users:

Travel Survey Shop Loop Crew, Transportation District Traffic Count Staff and Electricians.  Contractors installing traffic recorder stations.

How idea meets criteria:

Successful over time.

This product has been used since 2001 to install over 200 piezoelectric sensors around with very few failures.

Qualitiable results:

The product is tack-free in two to three minutes and the road can be reopened to traffic in 30 to 60 minutes versus the 4 to 10 hours required for other products.
