State Departments of Transportation Embrace CRCP – and
Offer Solutions to Commonly Encountered Challenges
Individual case-history reports are available for projects in seven states
where CRCP is frequently used:

CRCP: Virginia is for Innovation
The Virginia Department of Transportation first used CRCP in 1966-1967
on a 15-mile stretch of Interstate 64 through Richmond. By 1972, there
were a total of 185
miles of CRCP in the state. The most recent Virginia CRCP projects are
10-inch-thick CRCP on Route 288 in Chesterfield County and 12-inch-thick
CRCP at the Madison
Heights Bypass in Lynchburg. The state's Smart Road near Blacksburg also
contains a CRCP section, as well as asphalt and jointed concrete pavements.

CRCP in Louisiana - Then and Now
In designing and constructing the Interstate system in the 1960s
and 70s, the Louisiana DOTD experimented with a number of pavement
types, including continuously reinforced concrete pavement
(CRCP).

CRCP in Georgia — Durable Pavement
on Their Mind
In 1970, a 2-lane, 10-mile-long section of I-75 near Macon was built with a 7-to-8-inch
thick CRCP overlay on an existing, but deteriorated, pavement. In 2003, the Georgia
Department of Transportation replaced the truck lane with new 8-inch-thick CRCP,
while the passing lane was being rehabilitated.

Paving the Prairie States — CRCP's
Success in North and South Dakota
CRCP has been built in North Dakota since the early 1960s, as both full-depth
pavement and as overlay on top of jointed concrete pavement. As of 2001, 105
centerline miles remain in service. The most recent CRCP project in the state
is 8.7 miles of roadway on I-94 eastbound from New Salem, which was constructed
in 2002.
Since 1995, the South Dakota Department of Transportation has replaced 88 centerline
miles of asphalt pavement on its Interstate system with CRCP, for a total of
241 centerline miles of interstate, one-third of the state's total. South Dakota's
original application of CRCP, a one-mile-long trial section, is still in use.

Texas I-35 — Paving the Way for Free
Trade
This report relates the transformation of one vital stretch of Texas Interstate
35 from a two-lane country road to a six-lane superhighway for international
trade. It has been estimated that there are more miles of CRCP than all other
states combined in Texas, where CRCP has been used for 85 percent of the Interstate
system and over 50 percent of the primary and secondary system.

CRCP — The Illinois Experience
The State of Illinois has used CRCP continuously since its first project
in 1947. This report describes the stellar performance of the expressways
built in the
Chicago area using CRCP. It highlights the successes of using CRCP on
the five central freeways through northern Illinois since the 1960s,
three of which
are among the 25 busiest expressways in the nation.

Oklahoma I-35 — Where Tough And Smooth
Go Hand In Hand
The first CRCP projects were constructed in Oklahoma in 1969, with 110 lane miles
being laid by 1972. Although CRCP design was not utilized again until 1984, there
has been a steady addition of CRCP to the state's pavement inventory. This report
describes the upgrading of Interstate I-35 through Oklahoma City, a major NAFTA
corridor. It describes the pavement design elements, including thickness, and
the construction strategies which resulted in an award-winning project.
