QTT, INC releases New Pavement Temperature and Condition System for International Customer

05-01-2007

(ST. LOUIS, MO  May 2007) – Quixote Transportation Technologies, Inc. (QTT), a leading provider of pavement sensor technology for road and runway applications, has released a new pavement and temperature reporting system known as the Passport for its international customers.  The Passport is a system that combines passive pavement sensor technology and a special interface to determine current pavement temperature and condition.  
The Passport system utilizes the FP 2000® passive pavement sensor to measure pavement temperature, chemical concentration, calculate the chemical freeze point and determine pavement condition.  The FP 2000 sensors are embedded directly in the roadway surface where the information is needed.  The Passport utilizes one to four FP 2000 sensors to measure conditions at different locations or lanes.  Then through a special interface, the Passport system can be used with almost any atmospheric weather station.  The information from the Passport allows operations personnel to know critical times when the pavement can become hazardous.
 
QTT’s FP 2000 is made of materials with similar properties as concrete or asphalt so that it can accurately measure pavement temperatures.  The sensor also uses four-point conductivity to passively measure chemical concentrations of the water/ice/deicing solution on the sensor surface.  The unique indented well in the FP 2000 collects sufficient moisture and provides an accurate analysis of the surface solution. 

The Passport will report simple pavement temperatures and conditions if used as a stand-alone system.  However, if used with an existing weather station, the Passport can produce valuable surface conditions by using the atmospheric data from the weather station.  These calculations are made by a high-tech surface algorithm known as STORM Vision, which uses a variety of parameters to accurately calculate the surface condition.  A subsurface temperature probe can be used in place of one of the surface sensors for added information about the location.

 “The Passport is a beneficial product for our international customers,” comments Jon Tarleton, Marketing Manager for QTT.  “It provides critical pavement data for highway maintenance operations, and its ability to be used as either a stand-alone system or part of an existing weather station makes the Passport a cost-effective solution.”
