Pavement Design & Materials

The base and sub-base layers sit between your surface course (asphalt or concrete) and the native subgrade. They distribute traffic loads, provide frost protection, and create a stable platform for paving equipment. Because traffic volumes, truck percentages, and utility demands vary dramatically be…

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…
