MIT DowelSCAN – Faster

The MIT-DOWEL-SCAN system provides nondestructive testing of dowel bars in plain concrete pavements as soon as you can walk on the concrete.

• Faster Set-Up in the Field – No rails to assemble or move

• Truly a single person operation – pick up the laser & push the device to the next joint

• Faster joint relocation & alignment allowing more completed tests per hour

MIT DowelSCAN – Simpler Configuration

Improved design eliminating system components. Hard wire connection, removable battery.

• Single Transport Case

• Integrated Data Collector attaches to the scanner

• Easier Battery Charging - Data Collector includes scanner battery detaches for charging.

• Real Time Results: magnetic image map is generated as the joint is scanned. Quantitative results shown immediately after scanning the joint

MIT DowelSCAN – Accurate

411/26/2018

The MIT-DOWEL-SCAN system is still very accurate & repeatable – Provides depth, translations, deviations, skew and tilt to within tenths of an inch precision.

• MIT-DOWEL-SCAN has 10 sensors and a laser to guide the unit along the joint with same great accuracy and repeatability

• Easier transfer to MagnoProof 5 with USB A port on the data collector.

• Post test data processing is via a 10 sensor/signal version of MagnoProof 5

• Meets ASTM E-3013

MIT DowelSCAN – Laser Alignment

511/26/2018

• Joint alignment is fast:– Set the “AA” battery powered laser on

the edge of the pavement

– Align the scanning unit with the laser using the green lights in front. Red lights appear when not aligned

– Retract transport wheels

MIT DowelSCAN – Automatic Alignment

611/26/2018

• Scanning Unit automatically maintains alignment during the test.

• The operator does not steer the device during the test

• Allows observation of the real time mapping

MIT DowelSCAN – Product Improvements

711/26/2018

• Firmware revision to address bright sunlight interfering with alignment

• Modified encoder configuration to maintain the 1mm gap with the wheel

• Laser battery case reinforcement• Improved transport case foam• Increased the thickness of the laser foot• Increased thickness of cable support clamps• Working on reducing the number of cover screws

that shear off during shipment• Supply Chain improvements will reduce lead time

MIT SCAN-T3 - Thickness Gauge

8

• Meets AASHTO Standard Test Method T359-18 Pavement Thickness by Magnetic Pulse Induction – eliminates cores for thickness

• Replaces the popular MIT SCAN-T2• Very accurate less than +/- 3/16” on

13” pavement• ASTM Standard in Balloting should

be issued Spring of 2019. Includes reflector material specifications

MIT SCAN-T3 – New Features

9

• Added GPS – can return to the reflector location quickly

• Added additional sideways search bar - to assist in locating reflectors quickly

• Replaced the keypad with a mouse button

• Can automatically detect reflector size & type

• One piece design prevents accidental interchanging of head and main body.

MIT SCAN-T3 – New Software

10

• Improved firmware provides alerts –including moving too fast & starting to far from the reflector

• Allows preloading of test location descriptions

• New software that produces reports and performs statistical analysis of multiple tests.

• Software allows use of inches to “X.X5 or X.X0”
