chapter 3 rigid pavement - DOT On-Line Publications - Department ...

We recognize that some States have been working in strengthening their asphalt
concrete mix design and field control practices. These efforts are appropriate
and continued involvement of all the field offices in encouraging conformance
with the attached TA will be expected.
Other factors such as truck weights, high tire pressures, etc., also contribute
to the rutting and stripping problems and we are working on these issues. We
are convinced though that significant gains in solving rutting and stripping
problems can be achieved by using quality materials and strengthening
specifications and construction practices. We expect those States where
rutting and stripping is a problem to include a priority effort to improve the
design and construction of asphalt concrete pavements. The Pavement Division
and the Construction and Maintenance Division are available upon request to
provide technical support and guidance, which may.be necessary in achieving
these actions.
