The Cost of Waiting: 4 Signs You’re About to Miss the Micro Surfacing Window

Road engineers rarely face a shortage of pavement needs. The challenge is deciding which roads need attention now and which can wait another budget cycle. A roadway that could be preserved today with micro surfacing may require significantly more expensive rehabilitation just a few years later. By the time visible distress becomes severe enough to command immediate attention, the most cost-effective treatment option may no longer be available.

Friction Testing: Reliable Pavement Decisions Need Reliable Data

Transportation agencies make decisions worth millions of dollars every year based on pavement condition index (PCI) data. But before that data can inform a decision, agencies need confidence that the equipment is collecting accurate information. The Illinois Certification and Research Track (ICART) is a specialized facility developed by the Illinois Department of Transportation (IDOT) to support pavement research, equipment certification, friction correlation and evaluation of pavement measurement technologies.

Pavement Preservation Resource Center

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.

Rethinking Preservation with AMIGUARD™ RPE-R in Monroe County, Michigan

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.

Why Rheology Matters: Measuring Topical Rejuvenator Impact on Asphalt Performance

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.

The Logistics Behind Longer‑Lasting Roads

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.

Critical Issues and Misconceptions in Spray-Applied (“Spray-On”) Asphalt Rejuvenation

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.

How Wisconsin Highway Leaders Stretch Every Road Mile

When five Wisconsin highway commissioners recently gathered to talk pavement at the Wisconsin County Highway Association winter meeting, the conversation wasn’t small talk — it covered managing lane miles, overcoming air voids and understanding treatment options that can extend road life. Each leader carried the same mission: make roads last longer, cost less and perform better, despite stagnant budgets and growing challenges.
