Paving
As a durable, economical and low-maintenance concrete material, roller-compacted concrete (RCC) is steadily becoming the choice for many pavement applications. And researchers in Louisiana are testing just how thin those applications can go.
Traditionally, RCC pavements have been built with an 8...

Figure 1. The study area in coastal N.H. showing the locations of the five pavement evaluation sites, the magnitude of groundwater rise, the areal extent of the groundwater-rise zone (GWRZ), and the extent of surface-water inundation with 6.6 ft of sea-level rise.
The rate of sea-level rise caused by climate change is predicted to accelerate as warming ocean waters expand and water is added from melting land ice.
The rising sea level makes maintaining road infrastructure near the water increasingly challenging. Street flooding in many coastal communities...

No matter what the purpose, today’s network of more than 2.68 million miles of paved...
Pavements tend to deteriorate over time under repeated traffic loads and/or certain environmental conditions.
By detecting pavement distresses and damage early enough, it is possible for transportation agencies to develop more effective pavement maintenance and rehabilitation programs and thereby...
