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.
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
