Pavement design isn’t just about strength, smoothness, and cost anymore. It’s also about sustainability-how each material and process affects the environment across its entire lifespan. That’s where Life-Cycle Assessment (LCA) comes in. This analytical approach measures the total e…

Why End-of-Life Strategy Matters When an asphalt or concrete pavement reaches the end of its service life, owners face a pivotal choice: remove and replace the structure in its entirety or harvest maximum value from the existing layers. The latter approach, designing an end-of-life (EOL) strategy, c…

A pavement is only as good as the ground it rests on. Accurately characterizing subgrade strength and stiffness is therefore one of the most consequential steps in pavement design. From rapid field tools like the Dynamic Cone Penetrometer (DCP) to sophisticated laboratory measurement of resilient mo…

Comparing Pervious Concrete, Porous Asphalt, and Interlocking Concrete Pavers (PICP) Why Permeable Pavements Matter Conventional pavements shed rainfall almost instantly, sending large volumes of runoff, and its pollutants, into pipes, channels, and ultimately receiving waters. Permeable (a.k.a. per…

When building or rehabilitating roads, poor soil conditions can quickly turn a solid plan into a maintenance headache. Stabilizing subgrade soils improves load-bearing capacity, reduces swelling, and extends pavement life, but choosing the right method depends on local soil properties, climate, envi…

A “long-life” or perpetual asphalt pavement is engineered so that the bottom of the asphalt structure never experiences fatigue cracking during its design life (often > 50 years). When distress finally appears, it is confined to the upper few inches and can be removed with a mill-and-…

Small cracks rarely stay small. Moisture and traffic turn a hairline fissure into potholes, base failures, and, eventually, a full-depth reconstruction bill. Two frontline countermeasures keep that progression in check: crack sealing and crack filling. They share the same goal, keep water and incomp…

(Why targeting the “vital few” miles, and dollars, pays off) What the 80/20 Rule Is The 80/20 Rule, or Pareto Principle, states that roughly 20 percent of inputs generate about 80 percent of results (investopedia.com). Though the split is seldom exactly 80/20, it’s a useful lens fo…
