Weigh-In-Motion (WIM) technology has revolutionized how we monitor heavy vehicles by allowing dynamic truck weighing<\/strong> without stopping traffic. Now, a new generation of fiber optic weigh-in-motion sensors<\/strong> is pushing this innovation further. These weighing sensors<\/strong> offer exceptional longevity and reusability, addressing many challenges faced by traditional WIM systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

For road authorities and operators, the lifetime of weigh-in-motion sensors<\/strong> is a critical concern. Highways and bridges are expensive assets, and managing them involves periodic maintenance like asphalt resurfacing, repairs, and upgrades. Traditional WIM sensors often need replacement during these works, leading to extra costs and traffic disruptions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A reusable weigh-in-motion sensor<\/strong> changes this equation by allowing the same sensor to remain in place or be reinstalled after road work, saving both money and downtime.

Fiber optic weigh-in-motion sensors<\/strong> represent a major leap forward in addressing the shortcomings of earlier WIM technologies. In fiber optic WIM systems like BISON WIM<\/strong>, the sensing element is an optical fiber (or fiber Bragg grating) integrated into a robust carrier (such as a steel strip or plate). The fiber measures strain or pressure by changes in light signals, rather than relying on electrical output from crystals or strain gauges. This design brings several key advantages:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Fiber optic sensors are inherently resistant to fatigue. Glass fibers don\u2019t wear out from millions of bending cycles the way metal strain gauges do.<\/p>

In fact, fiber Bragg grating sensors are noted as promising for long-term monitoring in harsh environments<\/em>, effectively replacing conventional strain gauges. Real-world evidence is now emerging: in one case, fiber-optic WIM sensors demonstrated exceptional durability and stable functioning over years of heavy use.<\/p>

The BISON system\u2019s innovative fiber optic technology has been confirmed by independent evaluators to provide durability and stability of functioning<\/strong> in the field. Manufacturers estimate these fiber optic WIM sensors can last decades; for instance, BISON\u2019s stainless steel + fiber optic plates are engineered for an estimated lifespan of 30 years.<\/em>\u00a0far outliving most older sensor types. This longevity translates to lower total cost of ownership and fewer headaches for road operators.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Reusable Design:<\/strong><\/span> Perhaps the biggest game-changer is that fiber optic WIM sensors like BISON are built with reusability in mind. The sensor plates can endure road work and be used again, rather than being disposable.<\/p>

BISON weigh sensors are reusable; it is possible to re-asphalt the road without damaging the sensors<\/strong>.<\/strong> This means if a road needs a new overlay of asphalt, the construction crew can pave over the flush-mounted fiber optic sensors, then calibrate the system, and it will continue functioning \u2013 no need to rip out and replace the sensors for a simple resurfacing.<\/p>

Moreover, if the road is completely reconstructed or if the WIM site needs to be moved, the fiber optic plates can be fully recovered and relocated<\/strong> to the new site. The plates are sealed and removable: they can be lifted out for maintenance or reinstallation without requiring a whole new sensor purchase. This reuse capability is unique to fiber optic WIM solutions<\/strong> like BISON and represents a fundamental shift from the \u201cembed and replace\u201d model of the past.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

One of the most strong advantages of BISON\u2019s fiber optic WIM<\/b> sensors is how well they handle road maintenance events. Whether it\u2019s a routine asphalt overlay or a full-depth reconstruction, these sensors are designed to either survive in place or be recovered intact<\/strong>, unlike traditional sensors which often must be junked. Let\u2019s look at a few common scenarios:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Resurfacing a road involves laying a new layer of hot asphalt, typically at 150\u2013180 \u00b0C (300\u2013350 \u00b0F)<\/strong>. Such high temperatures can damage delicate electronics or polymer-based sensors<\/strong> used in conventional weigh-in-motion (WIM)<\/strong> systems, which must often be removed to avoid heat damage.<\/p>

Fiber optic WIM sensors<\/strong>, such as BISON<\/strong>, are designed to withstand these harsh conditions. Their sensing element<\/strong>\u2014an optical fiber encased in steel<\/strong>\u2014contains no plastic components or electronic circuits<\/strong> beneath the pavement. Both steel<\/strong> and optical fiber<\/strong> tolerate short-term exposure to hot mix asphalt and the heavy compaction forces<\/strong> during installation. Unlike some piezoelectric materials<\/strong>, BISON\u2019s fiber optic plates do not soften or deform under heat<\/strong>, maintaining their functionality even through road resurfacing<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

When a road is due for an asphalt overlay<\/strong>, most weigh-in-motion (WIM)<\/strong> systems require the removal or replacement of sensors<\/strong>. However, BISON fiber optic WIM sensors<\/strong> eliminate this need.<\/p>

Installed flush with the pavement<\/strong>, BISON sensors can stay in place even when a new layer (e.g., 5 cm of asphalt<\/strong>) is added. After resurfacing, the sensors may sit slightly below the new surface, but they continue to function accurately through the overlay layer<\/strong>. If necessary, the top of the sensor plate can be exposed or adjusted<\/strong> to match the new surface level\u2014without installing new hardware.<\/p>

Because BISON\u2019s sensing element<\/strong> is a steel-encased optical fiber<\/strong>, it easily withstands asphalt heat and compaction<\/strong>. After an overlay, only a calibration check and minor adjustment<\/strong> are needed, allowing the weigh-in-motion system<\/strong> to resume normal operation quickly.<\/p>

For highway authorities<\/strong>, this is a major advantage: the WIM installation survives multiple resurfacing cycles<\/strong> (typically every 8\u201315 years<\/strong>), avoiding the costs, downtime, and replacement<\/strong> that traditional piezoelectric strip sensors<\/strong> require. Fiber optic WIM sensors like BISON make re-asphalting maintenance-free<\/strong> for embedded traffic monitoring systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Weigh-in-Motion (WIM)<\/strong> technology measures the weight of vehicles in motion<\/strong>, without requiring them to stop on a scale. Using sensors embedded in the road<\/strong>, a WIM system records axle weights, gross vehicle weight, speed,<\/strong> and vehicle classification<\/strong> as vehicles pass at highway speeds. The real-time data<\/strong> supports traffic monitoring, weight-limit enforcement, toll-by-weight systems,<\/strong> and infrastructure planning<\/strong>.

Yes \u2013 one of the major advantages of fiber optic WIM sensors (such as BISON) is that they are reusable<\/strong>. After installation, they can tolerate road work like resurfacing without being removed, and even if they are removed (for road reconstruction or relocation), the sensors can be reinstalled and continue working. The fiber optic sensors are designed to be recovered intact and re-deployed, unlike many older WIM sensors which are destroyed when taken out. In practice, this means you can pave over them or move them to a new site, and they retain full functionality. This reusability saves cost and is a unique feature of fiber optic WIM technology.
