Stringless Technology in Iowa - cement.org
Known for its innovation in concrete pavements, Iowa took another leap forward with its completion of two stringless slipform concrete overlay projects in 2009. Stringless technology, as the name implies, replaces the traditional stringline with an electronic tracking process that controls the
Portland Cement Concrete Pavement Construction
JAMES D. GROVE, Iowa Department of Transportation SANFORD P. LAHUE, American Concrete Pavement Association More than 100 years ago in the small town of Bellefontaine, Ohio, city officials decided to build an experimental section of concrete street.

Long-Term Plan for Concrete Pavement Research
To meet a 30-year calendar design life, a pavement built today may need to withstand 70 to 100 percent more axle loads per mile than a similar pavement built 10 years ago. This track will focus on strategies, materials, and construction processes for long-life concrete pavements. It will address tools to help ensure long-life concrete pavements through data collection and usage of accelerated ...
Long-Term Plan for Concrete Pavement Research and Technology
Envisioning what we want concrete pavements to look like in the next 20, 50, or 100 years and developing a long-term research plan to make the vision a reality will require the industry to examine itself closely—and perhaps even redefine itself.
Road surface - Wikipedia
A road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course .
What Makes a Quieter concrete Pavement?
problem in recent years, the National Concrete Pavement Technology Center (National CP Tech Center) has amassed the largest database, to date, of concrete pavement surface characteristics. Th e database includes noise, texture, and friction measurements. Nearly 1,500 test sections throughout North America and Europe have been evaluated (4). From this eﬀ ort, an understanding of the ...
