      <title>Bringing Bridge Inspection into the Computer Age</title>
      <link>https://trid.trb.org/View/760469</link>
      <description><![CDATA[This article introduces an electronic data retention system for bridge inspections that has shown repeatedly that it increases efficiency and saves money well beyond the cost of the system.  This task specific software program, ScanPrint, is the first of its kind electronic data retention system for bridge inspections has shown repeatedly that it increases efficiency well beyond the cost of the system.  The system was developed for the French Vinci Group by their Advitam division.  ScanPrint relies on the owner and the consultant to define the parameters of a bridge inspection project, then automates the process and makes inputting, standardizing, and retrieving information .The article presents two project case studies to illustrate the success of ScanPrint: Advitam's first foray into the United States market came in 2001 on the Zilwaukee Bridge in Michigan, a project that resulted in an alliance between Advitam and Finley-McNary Engineers; for the second case. Advitam took its work a step further on the Rion Antirion Bridge in Greece, the company put its inspection and monitoring program in place during construction.]]></description>

      <title>Tracking Structural Stability</title>
      <link>https://trid.trb.org/View/759241</link>
      <description><![CDATA[The Reno Transportation Rail Access Corridor (ReTRAC) project, scheduled for completion this fall, is expected to ease traffic congestion and beautify downtown Reno, NV, by sinking 2 miles of on-grade rail lines into a 33-foot deep trench.   One of the challenges the project faced was to avoid undermining the foundations of existing structures, some of them historic buildings.  The article provides an overview of the installation of wireless tiltmeters on sensitive buildings which are located close enough to the trench alignment that construction activities inadvertently could cause structural deformation or foundation settling.  The use of digital tiltmeters to document the effects of trench excavation on the buildings provides a record of the structures' performance  as a defense against damage claims and protect the workers, the public and building owners from injury and property damage.]]></description>

      <title>Restoring the Peace</title>
      <link>https://trid.trb.org/View/759240</link>
      <description><![CDATA[Transportation noise is perhaps one of the most difficult to cope with, particularly for people next to a busy highway.  The federal government set noise standards for highways in the 1970s and linked highway noise reduction to approval for federal funding of highway projects.  This article uses the design of sound walls for Houston, Texas, uptown area as a case study to examine the factors considered to determine the best type of structure; the type of wall to be built; the wall's height; the strength of the soil that will support the wall and anchors; and local street codes that dictate how much load can be applied without affecting the structural integrity of existing infrastructure.  Precast concrete sound walls were chosen to provide a maintenance free, cost effective and attractive solution to combat highway noise for an upscale Houston neighborhood.  Not only is noise under control, residents said the walls provide privacy, improved view, and healthier lawns and shrubs.]]></description>

      <title>Geotextiles for Transportation Projects</title>
      <link>https://trid.trb.org/View/756817</link>
      <description><![CDATA[During the past 33 years, geotextiles have evolved from being new engineering materials with limited technical references to state of the practice materials with numerous design and technical tools.  Geotextiles are a family of industrial fabrics comprising polymeric fibers or yarns that are needle punched or woven to produce an infinite variety of strong, dimensionally stable construction materials.  This article looks at the benefits and saving behind the technology, specifically as that apply to transportation projects.  Geotextiles are used most commonly in the transportation market for construction of paved and unpaved roads because of their separation, reinforcement, and filtration functions.  Also, when used properly, geotextiles can save time and money, both now and in the future, while also providing environmental and aesthetic benefits.]]></description>

      <title>ROLLING OUT STANDARDS</title>
      <link>https://trid.trb.org/View/750307</link>
      <description><![CDATA[The last decade has seen a fast growth in the use of roller erosion control products (RECPs).  The Erosion Control Technology Council (ECTC) was created in 1992 to formulate and establish performance standards for RECPs.  Thanks to the standardized specifications, RECPs have proven to be a consistently efficient way to stop erosion on moderate to extreme slopes, low- to high-flow channels, and numerous other applications.  Also, they typically cost as much as 75% less than hard armor solutions.  Furthermore, RECPs provide the environmental and aesthetic benefits lacking in some erosion control alternatives, such as rock riprap and concrete paving. The ECTC is also coordinating its activities with organizations such as the Federal Highway Administration and the American Association of State Highway and Transportation Officials by assisting in their activities and ensuring that overlapping responsibilities are avoided.]]></description>

      <title>HELP! I'M OUT OF DIRT</title>
      <link>https://trid.trb.org/View/746983</link>
      <description><![CDATA[Civil engineers, surveyors and contractors have learned that poor estimates of shrink and swell, or mistakes in calculations, are often costly, resulting in significant construction claims or in poor cost estimates for transportation, infrastructure, and earthwork projects.  The article emphasizes that a consistent approach for calculating shrink and swell values will help eliminate errors in estimating material quantities on projects involving earthwork.  Always conduct a thorough subsurface investigation, including in situ testing and soil sampling to develop a quantifiable model of the borrow pit or cut area, to investigate available soil volumes, and to evaluate the heterogeneity of the deposit laterally and with depth.  It is important to keep in mind that the accuracy of calculations is no greater than the accuracy of estimates of the relevant soil parameters.]]></description>

      <title>IMPROVING RAILROAD INFRASTRUCTURE</title>
      <link>https://trid.trb.org/View/741699</link>
      <description><![CDATA[The benefits of public transit are well-documented: cleaner air, less highway traffic, and safer roads. More businesses in the U.S. are realizing that heavy rail provides the same intrinsic benefits as well as financial gains; the railroad industry set a record in 2002 for freight traffic of over 1.5 trillion ton miles. However, with passenger travel and freight transportation still rising, and federal funding for transit in a seemingly perpetual state of limbo, the question arises as to how can the nation's rail infrastructure keep pace with increasing needs for safety, durability, and technological innovations? This article attempts to answer this question, highlighting important research by the U.S. Federal Railroad Administration aimed at development of intelligent railroad systems that would integrate new sensor, computer, and digital communications systems into train control, braking systems, grade crossings, and defect detection.]]></description>
