At a Glance

Collect and identify areas of roughness and determine segment ride values before vehicles are allowed on the mat or pad. The electronic components are similar for each system with different characteristics for their own paving environments. The advantages are knowing what to expect when an inertial profiler or profilograph profiles the pavement and to diagnose paving issues while changes can still be made.

 

Asphalt On-Paver Unit

With the option of collecting a profile directly behind the screed, the roller operators can make real time decisions for smoothness while compacting the mat. SSI offers options to transfer smoothness data to computer monitors in view of the roller operators. This data can detect and navigate the roller to problem areas while the mat is still hot.

 

Concrete On-Paver Unit

Concrete pavers have been using real time profiling devices for years. A concrete paving crew can use a PSD plot and elevation data to visually show finishers the profile of the pavement and make corrections directly behind the pan before the pavement is textured. The PSD plot can be used to show reoccurring frequencies in the pavement; a trait benefitting the procedures of concrete paving. 

 

Screen Views

The profiling computer can be mounted anywhere on the paver; in view of the finishers behind, near the control panel on the bridge or near the machine control computer. The screen will show machine speed, the profile trace, current stationing and traveled distance, calculated ride values in IRI or PRI and a PSD plot for diagnosing recurring trends in the data. 

 

See It and Forget It

The on-paver systems were designed to run without inputs from the paving crew once the collection was started. It is optional for the crew to enter events to the data for changes in project conditions, temperature, vibrator frequency, visual mix changes and relevant construction events.

 

Accurately Match Profile Model

Below shows the tight profile measurement comparison between the CS7800 on-paver device and two well established profiling devices: (i) the FHWA validated CS8800 walking profiler and (ii) the nationally certified CS9100 mid-mount inertial profiling system.  Measurements were taken over a tenth of a mile test track in the same wheel path with markings to ensure consistent device tracking.

Availability

SSI is finishing the engineering and testing on the CS7800 Dynamic Profiler.  We expect the device to be commercially available during the Summer of 2016.
