Reflectors for MIT SCAN-T2 & SCAN-T3 Pavement Thickness Measurements

MIT-SCAN-T2/SCAN-T3 Reflectors are used for pavement thickness measurements. Reflector discs come in 3 sizes and 2 different materials. Each device is calibrated to the specific size, thickness and metallurgy of the reflectors.
Materials are:

Aluminum- For Asphalt
7cm – minimum structural depth required is 15mm. Maximum measuring depth is 120mm.
12cm – minimum structural depth required is 40mm. Maximum measuring depth is 180mm.
30cm – minimum structural depth required is 120mm. Maximum measuring depth is 350mm.
Galvanized Steel- For Concrete
12cm – minimum structural depth required is 40mm. Maximum measuring depth is 180mm.
30cm – minimum structural depth required is 120mm. Maximum measuring depth is 350mm.
Proper Size depends on the thickness of the pavement your trying to measure.

Asphalt Pavement Applications:

The largest disc is used for measuring the thickness of the base coarse.
The mid size measures the intermediate coarse.
The smallest size measures the wear or surface coarse. Including typical Mill & Overlay thicknesses.

Concrete Pavement Applications:

The largest disc is used for new concrete pavement typically 12 to 13 inches in thickness
The 12cm diameter disc is used for overlay projects typically 5 to 7 inches thick.
A 14″ X 14″ reflector is available for Airport Runway or Taxiway thickness measurements up to 20 inches in depth.

Installation Notes:

Prior to paving, place the reflector on the existing layer.
Galvanized Steel reflectors include a center hole punched in them for a nail to hold it flat and in place while the paver progresses over it.
Place the aluminum pavers in the tack or seal coats in front of the paver.
In addition, be sure to place reflectors away from other metal objects such as tie bars and dowel bars. Both the SCAN-T2 or SCAN-T3 requires plain concrete or asphalt in front and behind the reflector during the measurement.

New Technology to avoid Concrete Shrinkage Cracks

KSE Testing Equipment (KSE) is excited to offer the first technology that directly measures capillary pressures in fresh concrete called the Capillary Pressure Sensor System (CPSS). By measuring the capillary pressure during the initial set period after finishing, shrinkage cracks can be avoided by adding moisture to the concrete surface when the alarm is triggered by threshold pressure limit. KSE is the exclusive seller of this system in North America. The complete system includes 4 pressure sensors, Wi-Fi base station, tablet for collecting data and software. On-site support is available. Please click on the ‘Tech Paper’ link at the top of this page to access our technical & research papers related to the CPSS and the technology behind it.
