Failing
streets, roads, and highways are a constant problem for cities, counties and
highway agencies. Many aging road systems need rehabilitation or reconstruction.
The problem: years of building low-cost roadways with unbound bases and thin
asphalt surfacing doom pavements to early distress and failure.
The most
efficient and economical way to rehabilitate these failed flexible pavements
is to recycle the existing roadway with cement. Small amounts of cement
will bind these granular materials together to form a semi-rigid base that
will
serve to carry traffic for a long time. The process uses base materials and
the aggregates in the asphalt surface. It allows the user to continue to
use the existing roadway while fixing more miles than conventional replacement
allows. It also conserves materials that are used for new pavements.
We hope this web site will give you the tools, information and resources necessary
to initiate your own recycling program or build upon your existing one. Please
know that CCT is here as a technical advisor, as a research resource and as
people who care about building strong roads.

Since 1996,
Fort Worth’s street maintenance program has saved taxpayers millions of
dollars by recycling the city’s deteriorating and failed asphalt streets
with cement. The city has rebuilt 296 lane-miles or 2.26 million sq. yd. of
roadway using full-depth recycling (FDR) with cement, according to Najib Fares,
the city’s street program manager. [Full
