>As part of our ROMDAS road measurement equipment we have two low-cost
>instruments for measuring road profile from which the roughness in IRI and
>PSD can be calculated.
>
>The Z-250 is a small, portable manual profiler which is similar to the Face
>Dipstick, but about 1/3 the price. It is 'walked' along the road and the
>elevation profile (in mm) recorded every 250 mm on a Pocket PC. The output
>is a .ERD file which can be directly analysed using the UMTRI's RoadRuf
>software for PSD.
>
>Our inertial profilometer is also portable, but is attached to a vehicle
>which is driven down the road. It consists of a 16 kHz laser with an
>accelerometer and ethernet output. It records the elevation profile and
>produces a .ERD file while also giving the IRI in real-time. The pricing on
>this is still being finalised but it will be the lowest cost profiler
>available. We will have one at the Pavement Evaluation Conference in
>Virginia at the end of October if you will be attending.
>
>The Z-250 and inertial profilometer can be rented or purchased. We give
>discounts to universities.
>
>Both are described in the newsletters at www.ROMDAS.com. The web site also
>contains manuals, reports on instrument validation, calibration, etc. as
>well as our catalog.
>
>We also have a free CD with all the material on it. A copy can be requested
