Laser Inertial Profiling - ASTM E950 & ALDOT 448-12
Skyline Drive, waynesboro, va
Trimat Materials Testing now has the capability to provide pavement smoothness testing utilizing the Ames 8200 High Speed Laser profiler equipped with dual 3 kHz GoCator lasers. This device has the ability to calculate Profile Index (PI), International Roughness Index (IRI), Half-car Roughness Index (HRI), Ride Quality Index (RQI), and Ride Number (RN).
Trimat is now certified with the State of North Carolina and our device and operators meet NCDOT Requirements.
The GoCator 3kHz lasers, built by LMI Selcom features include:
Best choice for use on ground or longitudinally tined concrete surfaces
Reduces inflated IRI and PI values caused by pavement texture
Bridges transverse and longitudinal joints; and reduces their effect on profile measurements
Better profiler repeatability on textured surfaces, meets ASTM E 950
Currently in use for QC/QA testing by state DOT’s as well as paving contractors
North Carolina is in the process of moving from the current Hearne Straightedge for acceptance to this more advanced technology and Trimat can provide this service for any NCDOT project. We can arrive onsite at anytime during the construction process, and within a few hours complete our testing. This device can be used under traffic with no adverse effects to the traveling public, or used on new construction to monitor smoothness so any corrections can be made if necessary.
The Ames 8200 meets or exceeds ASTM E950 Class 1 profiler specifications, and AASHTO PP 51-02.
