Hot In-Place Recycling is a cost-effective approach for repaving worn asphalt pavements. See how it works and why it’s more cost-effective than traditional methods.
Shortly after World War II, the federal government and the municipalities began building airports in all parts of the country. Most of them were constructed with asphalt due to lower initial cost and the Asphalt Institute’s valuable technical help given to the Corps of Engineers during WWII. La...
For the area enclosed by the performance curve, thin HMA overlay effectiveness ranges from 40 to 360 IRI years (where IRI is in inches per mile), 0.13 to 0.76 RUT years (where RUT is in inches), and 7 to 130 PCR years (where PCR is on a 0 to 100 scale). The wide ranges of ...
For me, at the end of the day it all comes down to this quirky fun factor. Knowing that the total cost of ownership on an electric will help bring down the cost of the machine over the long-term, I’d justify the extra expense of the BRD on the fact I enjoyed the experience on ...
“This is the first technology to offer cost effective and safe wireless on-the-go charging for electric vehicles,” Ezer continued. “It is exciting since it deals with the obstacles in the massive shift towards public electric transportation and thus has the potential to create a global transp...

On average, milling operation can decrease the as-built pavement roughness by 7 inches per mile. The post-overlay flexible pavement service life mainly depends on the relative relationship between overlay thickness and annual average daily truck traffic (AADTT). In addition, unbounded subbase, fine...
