Can You Have Both Rumble Strips and Longer-Lasting Roads?

J-Band
Rumble strips are a low-cost measure used to address one of the most serious types of traffic crashes: a lane departure crash. They consist of a set of transverse grooves applied on the shoulder or centerline of a roadway. An example of a road with centerline rumble strips. In Ohio,...

Dakota County Minnesota Building Longer-Lasting, Safer Roads

J-Band
Many states are looking for methods to improve longitudinal joint performance of their asphalt pavements since these joints often fail before the rest of the surface. With their inherently lower density, longitudinal joints fail by cracking, raveling and potholing because of the intrusion of air and water. Due to their longitudinal joint issues,...

Rural Roadway Departure Accidents – An Alarming Trend that Needs Reversed

J-Band
Reducing fatalities on rural roads remains a major challenge in the United States. In 2016, 18,590 lives were lost on rural roads-more than half of all traffic deaths-even though only 19 percent of the U.S. population lives in rural areas. Two-thirds of these rural fatalities involved a roadway departure, where...

Eau Claire County Wisconsin Using VRAM to Fill Air Voids in Centerline Joints

J-Band
Studies have shown that longitudinal joints in pavements are often the weakest areas of a road. Typically the joints are low in density, high in voids and thus are highly permeable. These areas become conduits to air and water infiltration which leads to damage and premature pavement failure. (1) VRAM...

Calumet County Wisconsin Helping to Create Longer Lasting, Safer Roads

J-Band
Many states are looking for methods to improve longitudinal joint performance of their pavements, since these joints often fail before the rest of the surface. With the inherently lower density at the longitudinal joints we often see pavements fail by cracking, raveling, and potholing. Lower density is synonymous with higher...
