Every pavement network deteriorates over time, but not every roadway follows the traditional deterioration curve that leads to costly rehabilitation or reconstruction. The most successful agencies understand that the right pavement preservation treatment, applied at the right time, can extend pavement life, improve condition and delay more expensive repairs.
How do you get more life out of a pavement you’ve already invested in?
For Jersey County, Illinois, preserving pavement and extending service life means understanding what a road needs at different points in its lifecycle and choosing treatments accordingly.
Meet Diane Franseen, Lab Manager at the Asphalt Materials, Inc. (AMI) Portage Terminal, H.G. Meigs! For more than 26 years, Diane has been integral in ensuring the quality of our material production.
This season, Monroe County, MI added to its long-standing commitment to building stronger pavements through the application of AMIGUARD™ Rapid Penetrating Emulsion Rejuvenator (RPE-R), a spray-on asphalt rejuvenator from Asphalt Materials, Inc. (AMI). The work included applications on several county roadways as well as the newly constructed Monroe Loop Path, a walking and recreational trail stretching approximately 6.3 miles, demonstrating how application methods can be adapted for use on a variety of asphalt assets.
In 1956, Asphalt Materials, Inc. (AMI) began with a mindset that would define the next seventy years: never stand still.
Asphalt Materials, Inc. (AMI) is proud to support the Asphalt Emulsion Manufacturers Association (AEMA) and its Leadership Education for Asphalt Preservation (LEAP) program, an initiative dedicated to developing the next generation of leaders in the asphalt emulsion and pavement preservation industry.
Topical (“spray-on”) asphalt rejuvenators are an effective preservation solution to mitigate the effects of asphalt binder aging. Effectiveness of these treatments is determined by how the rejuvenator interacts and impacts mechanical behavior of the existing asphalt in response to traffic, climate and time. Rheological testing of the asphalt binder therefore provides the most practical and objective framework for evaluating rejuvenator performance.
When confronted with the need to widen a road, Union County, OH found this cost-effective approach using recycled asphalt and cold mix asphalt.
Road projects depend on materials arriving exactly when and where they’re needed. When deliveries happen without interruption, schedules stay on-track and work keeps moving forward.
That reliability doesn’t happen by accident. It’s the result of a logistics team working continuously behind the scenes to anticipate needs and manage the details so customers can focus on building longer‑lasting, safer roads.
Asphalt rejuvenation has been used for decades as a pavement preservation tool, but advancements in the category are not reflected in today’s spray-on asphalt rejuvenator (SOR) conversations. As a result, performance is often measured using outdated and sometimes proprietary frameworks, creating a disconnect in what’s being measured and what actually drives pavement performance. The challenge is not that rejuvenators lack supporting data, but that success metrics have not been reassessed as new technologies and research have emerged.
