OVERVIEW
|
|
SSI models of
high speed profiling systems are available on a variety of
unique hardware platforms designed to satisfy almost any end
user’s requirements and expectations. All models have a commons
set of data collection components installed onto the end-user’s
choice of vehicle platform. Choose between a
Robust Mount,
a
Portable Mount,
the cost effective
Simple Profiler
module, an
Integrated Mid-Vehicle Mount
(available only from SSI), a professionally engineered
trailer mounted
Multiple Purpose Profiling
System (available
only from SSI), or the
Smart Car
profiling system. The core components are modular in design,
such that all of the key profiling system components are
portable, “plug-and-play” instruments that can be easily
upgraded or replaced in the field.
The SSI high
speed profiling system features a digital data collection
architecture that generates surface profile data having a
greater degree of both repeatability and accuracy than
any competitive device. The high-speed profiler is a high
capacity tool that can be used to generate high-resolution
surface profile data throughout all project phases—from bidding
to final surface preparation throughout the period of any
contractual warranty. For basic surface profiling applications,
SSI offers single or dual laser high-speed profiling systems.
The single laser configuration can output dual wheel path
reports, with SSI’s patented ability to align separate data
collections from multiple wheel paths in the same direction on a
single report (with the results summarized and averaged). The
dual track systems collect both wheel paths of surface data
simultaneously. For advanced applications, several of the
systems can be configured with up to five lasers for measurement
of additional surface characteristics, such as rutting and
texture.
SSI high-speed
profiling systems are available with alternate laser sensors
designed for asphalt or concrete pavements. SSI profiling
systems instrumented with single point (“dot”) lasers are the
preferred laser for most asphalt applications, while SSI’s
“wide-footprint” sensors are preferred by the concrete industry,
where such specialty lasers help minimize the “ride value
inflation” effects of a single point laser on concrete pavements
finished with longitudinal tinning, diamond grinding or coarse
textures. SSI’s wide-footprint lasers are offered in two
configurations: (i) adjustable dot lasers sensors spaced closely
together, or (ii) the “RoLine” sensor manufactured by LMI
Technologies (producer of the popular “Selcom” brand of lasers
for road profiling applications. The RoLine laser reads a 4
inch/100 mm lateral scan of the surface and was specifically
designed for concrete pavement applications. All models and
sensor configurations are guaranteed by SSI to meet or exceed
agency specifications, certification requirements, and test
methods.
All models of
the SSI-Cox high-speed profiling system are capable of
pinpointing localized roughness (so called “must-grind
bumps/dips”) with unparalleled precision. SSI has the test
results and research data to support the superior accuracy and
repeatability capabilities of the SSI-Cox high-speed system. The
feature-rich Windows software programs offer incomparable ease
of operation and facilitate widespread use and sharing of
profile data among all parties interested in the profile
attributes of a surface throughout a project’s life cycle. The
superior attributes of the SSI-Cox high speed profiling system
evolve from patented technology and years of PhD level
professional engineering.
A portable
military specification Panasonic Toughbook with touch-screen
controls allows for easy, safe one-person operation. The
profiling system software allows instant viewing of profile
results and localized roughness. PDF images and ERD or Excel
format exports of the profile data are available by touching a
single button within the software. Simulation routines are
provided for predicting the corrected profile of an existing
surface after corrective grinding or overlay. Encrypted raw data
can be re-analyzed repeatedly with numerous adjustable data
reduction and filtering parameters.
The SSI-Cox
high-speed profiling system generates true ASTM Class I
profile data at speeds from 5 mph to 65 mph. Profile data
is backed up in real time, and the collection system suspends
itself when the vehicle drops below the minimum operating
speed. The system is supplied with three data collection
triggers, including SSI’s proprietary reverse direction
triggering method, which collects data with exact stations (chainage)
without pre-measuring or marking the test surface with
reflective tape or pylons. Photo-optic sensor and manual data
collection triggers are also supplied.
The SSI-Cox
high-speed profiling system meets or exceeds all applicable DOT
agency test methods and certification procedures. This includes
the industry’s most stringent certification protocols: AASHTO
PP51-02 and Texas Department of Transportation Test Tex 1001-S
(as administered by The Texas Transportation Institute).
To further
enhance the usefulness of the system, a GPS subsystem is
available with the GPS positioning displayed in real time,
correlated with profile data stations (chainage), and overhead
images of the data viewable in Google Earth. For
Survey,
Design and Machine Control
Options,
a high resolution,
differentially corrected GPS option creates a mobile surveying
platform on the profiling system vehicle.
With this configuration, the
high speed profiler’s data collection system adds an
embedded (board level) GPS receiver with a paired base unit for
collecting high accuracy, corrected GPS data. As a mobile
surveying vehicle, the system generates a higher resolution
surface topography map than conventional surveying methods in a
fraction of the time. The high resolution surface data file can
be used in standard engineering software for design
applications. The same GPS components can be detached and used
on other devices for site preparation and machine control
applications.

SSI’s
high- speed profiling systems have proven capabilities to
generate highly accurate, repeatable surface profile data.
These attributes are evidenced by the Figures below.
Figure 1
shows a comparison of the data from SSI’s high speed
profiling system as compared against independent survey
data.
Figure 2
shows a repeatability comparison of ten repeat same surface
data collections by the high speed system.
Figure 3
shows the system’s ability to reproduce the exact profile of
the test surface by showing the systems’ measurement of an
artificial bump of known dimensions.
Figure 1: Proof of Accuracy.
In Figure 1, the surface data collected by the SSI high
speed profiling systems is compared with high precision
against independent survey data. Figure 1 shows an example
of a point-by-point comparison of the profile data collected
by the SSI high-speed system at a one-inch sampling interval
as compared to an independent reference profile generated
with survey instrumentation on a test surface. The high
speed system’s data (the blue trace) overlays on the
reference survey profile with exact precision. On a running
point-by-point comparison, the accumulated difference
between the T3 system’s profile and the survey profile is
27.6 mils (0.0276 inches). This level of accuracy places
the SSI high speed profiling system as among the most
accurate of commercially available surface profiling
systems. Prior to delivering any high-speed profiling
system to an end user, SSI’s verifies that the collection
system compares against an independent reference profile
with a greater degree of accuracy than is required by any
agency specification or equipment certification requirement.
Figure 1: SSI High Speed Profiling System:
Proof of Accuracy vs. Survey Data
Figure
2: Proof of Repeatability:
The SSI
high-speed profiling systems are capable of generating
highly repeatable profile data. Figure 2 is an example of a
ten profile data collections on the same surface. This
figure shows the extremely close comparison of the
separately collected profile data traces. SSI guarantees
that all models of the high speed profiling system can
produce such highly repeatable profile data.
Figure 2: SSI
High Speed Profiling System: Repeatability of Multiple (10)
Data Collections on Same Surface
Figure
3: Proof of Ability to Reproduce the Exact Profile of the
Test Surface.
SSI’s high
speed profiling system has the proven ability to reproduce
the exact profile of the tested surface with a greater
degree of accuracy then any competitive system. Figure 3
shows the system’s ability to reproduce the exact dimensions
of an artificially constructed bump placed at a random
location on the test surface. The dark blue line shows the
artificial bump (10 feet long with seven 0.25 inch steps up
and then seven 0.25” steps down) placed from station numbers
292 to 392 on the test surface. Three collections from an
SSI high-speed profiling system run over the bump are
overlaid on the trace of the actual bump surface. The
high-speed profiler data reproduces the actual bump
dimensions with exacting precision. Other systems have been
observed to err in locating the longitudinal position of the
bump, to erroneously display the detected actual bump
surface as a numbed bell curve, or err in the height of the
detected steps by over one-inch from the actual height. All
of SSI’s high-speed profiling systems can reproduce the
profile of the measured surface with unmatched precision and
accuracy.
