Global Road Conference & Expo
What are some of the flagship solutions you are presenting at the Global Road Conference & Expo?
As the global leader in Non-Destructive Testing (NDT) technologies on concrete infrastructure assessment, NEXCO -West USA presents innovative solutions for bridge, road, and tunnel condition state assessment, inter alia:
Deck Top Scanning System (DTSS) is a vehicle-mounted camera system that captures both infrared (IR) thermography and high resolution (HR) visual images at highway speeds. It can estimate what area of a bridge deck needs repair and determine whether in-depth measures should be implemented. DTSS already satisfies major requirements and recommendations laid out by the Federal Highway Administration (FHWA), Federal Transit Administration (FTA), American Association of State Highway and Transportation Officials (AASHTO) element condition inspection, and the state’s Department of Transportation (DOT).

SmartEAGLE is an advanced Roadway scanning vehicle that is equipped with a 3D laser mapping system, a line camera system, and a line sensor able to record georeferenced 3D visual data at highway speeds. It is the ultimate crack-detection machine. It uses the International Roughness Index, required by the FHWA, which was developed by the United States National Cooperative Highway Research Program (NCHRP) and the World Bank.

Tunnel Scanning System (TSS) combines three imaging systems: IR thermography, HR visual imagery, and 360° imaging to provide a comprehensive structural deficiency analysis of tunnels. Compared to a hands-on inspection of an entire tunnel (or tunnel system), one pass with the tunnel scanner can pick out places of concern and save considerable man hours. By mounting the system on a proper vehicle, it can scan railway tunnels, road tunnels, or cable tunnels. Click the link below to view our TSS brochure.
What mobility challenges do they address?
NEXCO-West USA’s Inspection Technology combines visual and Infrared imaging systems to generate a dual image of a structure. This combination provides a comprehensive display of superficial cracks and subsurface delaminations that allows for data-driven, objective decision making for structural maintenance. The operating speeds of our mobile systems (10 - 70mph) rule out the necessity of lane closures even in times of heavy traffic. Our stationery systems provide virtual access to the sub-structures regardless of its location (over water and/or above ground). The analyzing process is conducted off-site, allowing for a reduction of about 20-30% of labor time and money, as well as an increase in safety for the inspectors. The deficiency map delivered provides the total area in need of repair to accurately estimate total cost for rehabilitation bids. NEXCO technology is determined by the Strategic Highway Research Program (SHRP2) and other research plans to be one of the most effective and reliable NDT methods. Our exclusive cooled sensor IR cameras enable high-speed data acquisition, reduce noise, and increase resolution. This generates a high-definition and high degree of accuracy imagery that enables long-term asset monitoring. Our systems also help track changes in deterioration, expedites allocation of repair efforts, and is a powerful tool for forensic inspection progressive studies or comparative studies over time.
As an exhibitor, what is the value of presenting your solutions at a Conference featuring a wide cross-action of actors from the public, private and academic sector?
NEXCO develops state of the art NDT systems for structural inspection. Our technologies are the cutting edge of development, proving beneficial to the researchers and academics in attendance. Additionally, the solutions we offer are in-line with the cost reduction strategies present within the private and public asset owners. Specifically, our systems minimize the economic impact of lane closures caused by traditional assessment methods since they operate at any speed from 10 to 80 mph. Current inspections are based on the experience of the inspector, thus leading to omissions and false detections. Our georeferenced systems avoid uninspected areas on the structure, providing objective and data-driven results that enhance the maintenance decision making process. NEXCO offers a comprehensive platform that brings benefits to inspection companies; from increasing the speed at which infrastructure inspection is executed, to saving both time and labor in the field. Our systems also provide asset inspectors with the means to virtually access areas of the infrastructure that are not otherwise accessible. Lastly, our solutions come with the safety that traditional methods of inspection do not provide, allowing inspectors to acquire data within a vehicle without being exposed to onsite dangers like traffic or hazardous environments.
