Top Rollouts
Once again it���s that time of year. Better Roads editors have assembled
their list of the top road products out there for you in 2012. It���s the
hardest, most pressure-filled story we write all year. So this is our list;
it���s unlikely to match yours from top to bottom. But it is a way for us
to acknowledge some of the companies, some of the engineers and
designers who did special thinking and working to bring us outstanding
products ��� to us and our ways of thinking the pick of them ��� in 2012.

APPLICATIONS & INNOVATIONS
The National Asphalt Pavement
Association help us take a look at perpetual pavement. It���s traditionally associated with major highways, but this lifeextending design also works for lowervolume roads and thin pavement rehabs.
Even pavements not originally designed
to be perpetual can be converted ��� one
inch of asphalt at a time.
Mixing Quiet
Road noise from pavement can be attacked in a number of ways.
Mixes are a key variable, and the use of rubber in an asphalt mix
can make a significance contribution to noise reduction according to
some test strips.
