Industry news and goings on

This year, the results indicate just enough positive news for us to say that the men and women in charge of America's bridges are somehow beating the odds. With a post recession economy and stalled Congress putting intense pressure on them to do more with less, they are. In an economic climate that says the numbers should be getting much worse, they are not. That's something special.
Recycled Asphalt Pavement (RAP) is an accepted part of asphalt mixes everywhere. Prima facie, it would seem the more of it you use, the better the results in terms of the economy, the environment and the road surface. Percentages are indeed going up, but it's not that simple. How much RAP can be used is a complex question that requires complex answers.
