Roughometer III

Introduction

The Roughometer III is a cost-effective, easy to install, portable device which provides objective and repeatable roughness results. The Roughometer III is a World Bank Class 3 roughness measurement device, which actually exceeds the specifications of the category. Whilst the Roughometer is a response-type roughness device, it eliminates the uncertainties associated with the vehicle, such as the suspension or passenger weight, by directly measuring the axle movement with a precision accelerometer. The system is suitable for use on both sealed and unsealed roads and is capable of collecting up to 13,000 km of data. Practical and easy-to-use, the Roughometer III provides a simple technique for road quality assessment and now has the advantage of an integrated GPS unit. Once a survey has been undertaken, the Roughometer III processing software enables the data to be formatted into custom graphs, tables and maps.

Applications

  • provide objective data for true evaluation of the roughness level of the road
  • objectively compare and analyse which roads are in need of repair
  • monitoring roughness deterioration trends

Falling Weight Deflectometers : LWDs for quality assurance

Introduction

Using a portable falling weight deflectometer, PRIMA 100 LWD, is the fastest, easiest and most secure way of bearing capacity determination and quality assurance of unbound layers. PRIMA 100 measures the surface modulus and presents results immediately to allow in-situ decisions.

Applications

  • Road construction:
    216PE PRIMA226 Control of road base structures such as (sub)base, base layer gravel, recycled concrete, recycled asphalt, slag and crushed aggregate. Isotope measuring and Protor cannot be applied for recycled concrete and crushed aggregate. For this purpose PRIMA 100 is well suited, as static load bearing testing is slower and far more expensive.
  • Ramps, parking spaces, terminals, etc.:
    Control of base structures for ramps, approach areas near industrial buildings, freight terminals, stocks, parking spaces, harbour terminals, etc.
  • Industrial flooring:
    Control of base structures before concrete or asphalt paving in industrial buildings, stocks, etc. In the three cases above the employer's consultant controls the E modulus values, as the E moduli form the basis of the movement structure design.
  • Excavations:
    In connection with excavations and re-establishment of road areas etc. the E moduli are determined frequently in connection with the excavation work and when re-instating, compaction should reach the same modulus value. In this way differential settlements are avoided.
  • Construction of interim haulroads for e.g. construction work and timber transports:
    In connection with construction of interim haulroads for heavy loads, the bearing capacity is controlled during construction as the bearing capacity requirements can be very demanding in these cases.
  • Construction with geogrids:
    In connection with structures containing geogrids for reinforcement of the sublayer, the measurements will show, whether the geogrid has the expected effect.

In most cases determining E moduli is more relevant than measuring compaction degrees. This means that it is more relevant to use a light weight deflectometer than to perform isotope measurements or use laboratory determined Proctor density for comparisons. PRIMA 100 is the first portable equipment to offer measurement of in-situ E moduli. This has not possible with portable equipment in the past. Isotope and PRIMA 100 measurements are done equally rapidly, whereas Proctor results will not be ready before the day after the measurements were performed.

Falling Weight Deflectometers : PRIMAX Trailer-mounted FWD

Introduction

The PRIMAX FWD trailer is the classic and flexible solution from Grontmij, Pavement Consultants. Mounted on a double-axle trailer it is independent of the towing vehicle and can be towed by any vehicle. The only cable connecting the trailer with the towing vehicle is the PC computer cable. The operator controls all FWD functions from the PC, which is placed in the towing vehicle. This makes the measuring work simple and easy and only one operator is needed for the work.

Modular principle:
The modular principle means that there is no need for investment in new equipment if the demands on the equipment change. All that is necessary to upgrade the equipment from a standard 7-150 kN FWD to a 7-250 kN Heavy Weight Deflectometer (HWD) or even to a 7-350 kN Super Heavy Weight Deflectometer (Super HWD) is to add more weights, a larger load cell and upgrade software. The trailer-mounted FWD can also be integrated in a van without having to invest in new basic measuring equipment. Bil 20Mm Like all FWD equipment from Grontmij, the standard trailer-mounted FWD is supplied with:
a) Personal computer
b) Windows FWD software
c) Time history module
d) Transport lock
e) DMI (Distance Meter Indicator) integrated in the software
f) Three temperature sensors
g) Four-split loading plate
h) 9 to 17 or more geophones
i) Warning lights
Additional functions can easily be added such as video or marking equipment, GPS (Geographic Positioning System), which allows presentation of data in maps or general plans on site.
Data processing:
For data processing Grontmij supplies RoSy DESIGN, a back-calculation software for both road and/or airport data analysis. However, files generated from the equipment can be applied in any other back-calculation program.
Safe and reliable system:
Grontmij attaches great importance to supplying safe and stable equipment and the available newest technology forms the basis of the FWD equipment. The PRIMAX software incorporates alarms that are displayed on the computer screen. If the operator ignores vital warnings, certain functions cannot be performed with the FWD e.g. in connection with measurement of pavement temperature: After having inserted the asphalt temperature sensor in a hole in the pavement, the sensor registers when the temperature is stable. The temperature is measured while the loading plate is placed on the pavement and cannot be raised before the temperature sensor is placed in its holder. The equipment cannot be driven to another position with the loading plate lowered down and strategically placed emergency switches allow the operator to stop the equipment at any time while operating manually.
 


PRIMAX Van-Integrated FWD

Introduction

The van-integrated PRIMAX FWD from Grontmij, Pavement Consultants is the solution when the equipment is used daily or very frequently. It is well suited for measuring in towns and densely populated areas, areas with a heavy traffic load or in areas where safe, accurate and quick manoeuvre is required, such as airports and when measuring concrete slabs. The van-integrated FWD equipment may be driven at normal driving pace and the clear and good view from the van while testing offers optimum road safety. VanThe FWD unit is well-protected in the van and leaves space for further equipment or even a small laboratory. Another possibility is to bring along the portable FWD, PRIMA 100 LWD. The combination of the traditional FWD equipment and the PRIMA 100 light FWD allows in-situ quality control in connection with rehabilitation of pavements or new constructions.

Modular design:
The modular principle means that there is no need for investment in new equipment if the demands on the equipment change. All that is necessary to upgrade the equipment from a standard 7-150 kN FWD to a 7-250 kN Heavy Weight Deflectometer (HWD) or even to a 7-350 kN Super Heavy Weight Deflectometer (Super HWD) is to add more weights, a larger load cell and upgrade software.

LTL-M mobile retroreflectometer

Introduction

  • Danish company Delta has unveiled its new LTL-M mobile retroreflectometer, which it says has taken about four years to develop.
  • The unit, seen at the recent Traffex show in Birmingham, UK, measures all types of road markings at a simulated distance of 30m "with the highest level of accuracy." The company says that the LTL-M is to be used mounted on a vehicle measuring retroreflection at normal traffic speed providing full overview of the condition of the road markings.
  • DELTA says the instrument operates with an accuracy of typically +/-5%, which is in line with DELTA's hand-held retroreflectometers LTL-2000, LTL-X and LTL-XL.
  • It uses the latest camera and illumination technology, which results in high accuracy independent of changes in the geometry of the system through an automatic image process compensating for vehicle movements.
  • Consisting of three units (the sensor mounted on the outside of the vehicle with camera, flashlight and GPS; processor inside the vehicle; and the graphical user interface/GUI Tablet PC placed next to the driver), the LTL-M was the subject of a study carried out by VTI, the Swedish National Road and Transport Research Institute. The results are reported in Evaluation of the LTL-M, Mobile measurement of road marking, compiled by Sven- Olof Lundkvist in 2010.

E-spott - Spot testing for road and layered surfaces.

Introduction

The e-Spott is an advanced ground Probing radar system designed specifically to measure the total bound layer depth of roads and other layered surfaces. Once the operator has activated the system by pressing the one and only button, signals begin to be transmitted into the ground. These are reflected back to the surface from any discernable material change and automatic recognition software is applied to identify those signals returning from the first significant layer interface. At the same time advanced signal processing determines the velocity of propagation within the first subsurface level and translates this into the depth reading. This all happens within 10 seconds of pressing the button and the reading is displayed for a further 10 seconds, allowing the operator ample time to record it if required. Activation of any GPR system within the UK or EU is covered by regulation and in the UK a licence is also required. The nature of the materials normally used to form the surface and binder layer of a highway have little effect on the e-Spott allowing it to distinguish between these and the base layer by their electromagnetic properties. This is possible where there is a significant difference between them. The e-Spott system is a transmission device operating between 600MHz to 2.5GHz and conforms with all current European technical standards for GPR based devices and specifically EN 302 066-1. Similar regulations may exist in other locations.
