Ames Engineering continues to work with our customers to develop products that will better meet their needs. As smoothness specifications have become more challenging throughout the nation, the paving industry has become concerned about the surface texture of both concrete and asphalt pavements, and the effects that it can have on smoothness measurements. Even the smallest increases in smoothness values can mean the difference between a contractor receiving a bonus or penalty. In 2003 our engineers developed the first wide spot, bridging laser designed to remove surface texture from profile smoothness measurements. The Ames TriODS sensor was the first step in successfully reducing both IRI and PI measurements.

In 2005, Ames Engineering partnered with LMI Selcom in successfully integrating the next generation in laser technology, called the RoLine. In October 2005, the American Concrete Pavement Association (ACPA) tested our Model 6200 Lightweight Profiler equipped with the RoLine sensor and found that it could significantly reduce the effects of surface texture on smoothness measurements.

The 3K RoLine is available on the Model 6200 Lightweight Profiler and Model 8200 High Speed Profiler. The sensor can also be easily retrofitted onto standard Ames profilers.

3K RoLine Features
·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
