Want to save time controlling the granularity and shape of granular mixtures?

The VDG40 is a «Videogranulometer» device that quickly measures the granularity and shape of road construction and civil engineering materials. This device replaces the traditional method of sifting aggregates and it happens to be faster than this one. The VDG40 can analyze very fine particles of aggregates that can be rejected during sieving, with excellent fidelity. Thanks to this device, the washing and drying of materials can be avoided, which causes a significant time saving due to repetitions.

What standard does this device work with?

This MLPC equipment meets the criteria of the XP P 18-566-2002 standard and is selected for

XP P 18-540 as an alternative test for particle size distribution.

How it Works ?

The VDG40 enables the VDG particle size curve to be determined quickly and precisely by image analysis.

• First, the camera will project a shadow constituting the contour of said particle.
• Then, it will determine the coordinates of said contour of the shadow of the analyzed particle.
• Then, the coordinates will be processed to approach the contour by several consecutive segments.
• To conclude, with all of these data collected and processed. The VDG40 will determine a criterion of morphology of the particle studied, divided by a treatment of relative positions of at least two consecutive segments.

What to remember:

• Speed of sample analysis
• Optional sample wash = time saving
• Compliant with XP P 18-566 (July 2002)
• Determination of a very fine particle granularity (fraction from 1mm to 63mm)
• Regular monitoring of quarry production

NextRoad continues to strengthen its position as a major road engineering company in France and abroad. Through recent additions to the group and expanded expertise, the group is broadening its services in road maintenance, pavement engineering, and testing equipment.

Today, NextRoad supports network operators, local governments, and mobility companies with advanced engineering, testing, and asset management solutions.

Expanding Infrastructure Engineering Expertise

Following the merger of Vectra and Qualys-TPI in 2017, NextRoad became one of the largest independent private companies in the French road engineering sector.

The addition of ACR further strengthens the group’s expertise in:

• Road infrastructure maintenance
• Pavement diagnostic
• Infrastructure inspection
• Structural assessment
• MRepair planning
• Laboratory testing equipment
• Environmental engineering

As a result, NextRoad now employs more than 200 people and continues to expand its national and international presence.

Strengthening the National Road Engineering Network

With the addition of ACR, NextRoad expands its network of road engineering agencies across France.

The group now operates through multiple regional sites, improving responsiveness and proximity for infrastructure managers and public authorities.

These engineering services support:

• Road network maintenance
• Highway infrastructure
• Airport pavements
• Bridges
• Infrastructure asset management

Moreover, local presence allows teams to respond more quickly to road inspection and repair needs.

Supporting Sustainable Infrastructure Management

NextRoad’s mission is to help infrastructure managers improve infrastructure performance while optimizing maintenance budgets and environmental strategies.

By combining engineering expertise, infrastructure diagnostics, and advanced equipment solutions, the group supports safer, more durable, and more sustainable transportation infrastructure.
