About Automatic Road Unevenness Recorder

Automatic Road Unevenness Recorder :

Automatic Road Unevenness Recorder comprises of a trailer of single wheel with a pneumatic type mounted on chaise over which are installed profile recording and integrating devices. The machine has panel board fitted with two nos. of electronic counters for counting the unevenness index value. The digital meter for unevenness index value from 50 mtrs. To 1000 mtrs. For automatic displaying of UI values Data Storage in memory to display on panel board. The operating SPEED OF THE MACHINE IS 30 + 1-1/2 KM/Hr, and is towed by a vehicle. Its wheel on the pavement surface and the vertical reciprocating motion of the axle is converted into unidirectional rotatory motion by the integrator unit, the accumulation of this unidirectional motion is recorded by operating sensor inserted in the circuit of electronic counter once for every one centimeter of accumulated unevenness. Wheel revolutions are also indicated on the other electronic counter through a sensor actuated by the cam fitted on the hub of the wheel after every one meter of the wheel movement. There is an arrangement introduced for digital display of unevenness index value with a setting of distance form 50 mtrs, to 999 mtrs. In this arrangement suppose we get the distance value of 50 mtrs. Then after every 50 mtrs. We will get calculated U.I. Values on the digital meter In such manner we can set distance in 200 mtr, and so on upto 9999 mtrs. There is a memory of keeping UI values upto last 999 memories. The machine can be supplied with a pair of transportation wheels which will permit towing speed upto 60km/Hr, without disturbing the accuracy of the unevenness measuring wheel.A motor is fitted on the machine which is driven through the sensor and electronic controller form the wheel of the unit and the vertical motion of the axle drives a pen which marks on the moving recording paper. The pavement profile is recorded on the recording paper in the ration of 1:400 for and 1:1 unevenness of the road surface.

USES:
The degree of surface finish or the, riding quality of the road/runway pavement can be assessed. The system will record surface irregularities of highways and runways, which can be immediately attended to for rectification. The records so obtained can be well studied for judgment and decision in classifying pavement surfaces by the authorities for serviceability of the pavement and stage for repair or upgrading. Helps in evaluating the performance of the Specifications adopted for roads and runways and the developments of unevenness with age and under traffic.
ADVANTAGES
Timely improving the riding quality will result in
Low maintenance cost of pavement and vehicles
Increase in the load carrying capacity of the vehicle
Prolongs the working life of the vehicles and the driver
Comfortable ride to road users
Less fatigue to d driver in the interest of road safety
Minimize stresses in both road structures and vehicles
SALIENT FEATURES
Helps in assessing and improving the riding quality of pavement
Gives unevenness index value of pavements
Data obtained with various units is inter comparable
Safe and stable in operations
Durable and dependable
Cent percent indigenous
A compact and versatile unit at economic price

Advanced Sensor Technology

Equipped with a contactless displacement sensor, the recorder ensures high-precision measurements of road unevenness. The sensor guarantees an accuracy of 0.1 mm and fast response time (<1 second), enhancing data reliability for bitumen testing applications. Factory calibration and user calibratable options further ensure consistent performance in diverse road conditions.

Seamless Data Management

Integrated with an automatic data logger and inbuilt SD card support, road profiler data is securely stored for later analysis. Users can swiftly transfer results via standard USB and RS232 interfaces, optimizing workflow efficiency. The device also provides live digital displays of test outcomes, simplifying monitoring during operation.

Rugged Outdoor Operation

Designed for Indian outdoor environments, the recorder ensures durability with IP54-rated protection and solid construction. It supports continuous runs, tests up to 3 meters wide, and operates reliably across 0C to 50C with humidity up to 85% RHmaking it ideal for tough road assessment tasks.

FAQs of Automatic Road Unevenness Recorder:

Q: How does the Automatic Road Unevenness Recorder measure road undulations?

A: The recorder uses a standard 300 mm solid rubber wheel paired with a contactless displacement sensor to detect and measure undulations as the device moves at test speeds of 2030 km/h. The system automatically logs data on road surface irregularities at a resolution of 0.1 mm.

Q: What are the benefits of inbuilt SD card support and integrated data logger?

A: The inbuilt SD card and integrated logger enable automatic, secure storage of measurement data, allowing users to easily transfer and analyze test results via USB or RS232 interfaces. This reduces manual data handling and increases efficiency in road assessment.

Q: When is calibration required, and how is it performed?

A: The instrument is factory calibrated for accuracy. Users can perform calibration as needed, especially after extensive use or maintenance, using the provided user calibratable options to maintain precise measurements in line with IS:13174 and IRC specifications.

Q: Where can the device be safely operated and mounted?

A: The recorder is designed for outdoor road conditions and can be vehicle-mounted for mobile testing applications. Thanks to IP54 protection, it withstands dust and water sprays, ensuring safe operation on various bitumen-covered surfaces.

Q: What is the process for conducting a road unevenness test using this equipment?

A: To conduct a test, the instrument is mounted to a vehicle and positioned over the road segment. It performs automatic profiling as the vehicle moves, logging measurements in real time and displaying results on the LCD/LED screen. One specimen can be tested at a time, with flexible width accommodation.

Q: How is the recorded data accessed and utilized?

A: Test data is automatically recorded onto the SD card and can be exported using standard USB or RS232 ports. Users can analyze the results for compliance, maintenance planning, and road quality assurance, benefiting from high accuracy and prompt data availability for decision-making.

Q: What advantages does the IP54 protection offer for outdoor applications?

A: IP54-rated protection ensures reliability in challenging outdoor environments, guarding the instrument against dust ingress and water splashes, which is critical for uninterrupted road testing even under adverse weather conditions.
