TransTech Systems Model 380 PQI Builds on 25 Years of Non-Nuclear Tech
BY AsphaltPro Staff
TransTech Systems invented an innovative use of capacitance technology and has continuously developed and improved it over the course of 25 years for the use of non-nuclear technology for quality control in determining in-process asphalt density. A quarter of a century ago, TransTech Systems invented and patented the use of a well-established electrical technology for a new purpose: characterizing asphalt during construction and determining its density in a matter of seconds.
The first prototype for this technology, developed for determining the density of longitudinal joints, became the Pavement Quality Indicator, or PQI 100. Since this first commercial unit was introduced to the marketplace, TransTech has continuously made advancements to its flagship product in order to improve its accuracy, reliability, ruggedness and user-friendliness for a wide variety of mixes and conditions, according to the manufacturer.
The latest fourth generation Model 380 features items such as a GPS status display, the ability to download files to/from the PQI via USB drive, a touch screen GUI, and an advanced data management system.
The PQI is now used worldwide, and the company has distributors in over 87 countries. When combined with the Soil Density Gauge, TransTech has over 5,000 units in use every day.
