2 editions published in 2009 in English and held by 7 libraries worldwide
Detection of voids in prestressed concrete bridges using thermal imaging and ground-penetrating radar ( Book )
2 editions published in 2008 in English and held by 7 libraries worldwide
Thermal imaging and ground-penetrating radar was conducted on concrete specimens with simulated air voids. For the thermal imaging inspections, six concrete specimens were constructed during the month of June 2007 to simulate the walls of post-tensioned box girder bridges. The objective was to detect simulated air voids within grouted post-tensioning ducts, thus locating areas where the post-tensioning steel strands are vulnerable to corrosion. The most important deduction taken from these inspections was that PT-ducts and simulated voids were more detectable in the 20 cm (8 in.) thick specimens than in the 30 cm (12 in.) thick specimens
Interpretation of geotechnical properties of cement treated soils by Balasingam Muhunthan( Book )
2 editions published in 2008 in English and held by 7 libraries worldwide
This study first presents a critical examination of the use of various additives on soil improvement projects. It then presents a comprehensive examination of the effectiveness of cement treatment on geotechnical properties of soils from Aberdeen, Everett, and Palouse regions from the state of Washington. The addition of cement was found to improve the drying rate, workability and compaction characteristics of the soils
Seismic assessment of WSDOT bridges with prestressed hollow core piles by William F Cofer( Book )
2 editions published in 2009 in English and held by 7 libraries worldwide
There are 22 bridges with hollow-core pile foundations in Washington State. Sudden, catastrophic failure has been observed in tested piles of this configuration at displacement ductilities of four or less. To investigate the behavior of these piles and predict their in-service strength, a series of detailed nonlinear 3-D finite element (FE) analyses were performed. In addition, simplified 2-D nonlinear Winkler beam models were developed to evaluate their ability to predict failure. The modeling techniques were calibrated through simulation of experimental test specimens and shown to be capable of capturing the behavior of prestressed hollow core concrete piles

Use of ring nets for slope protection for rockfall : end-of-construction report ( Book )
2 editions published in 2009 in English and held by 6 libraries worldwide
Double-twisted hexagonal wire mesh has generally been applied to slopes with rock blocks less than 2 ft in size, while wire rope cable nets have been employed where larger blocks, typically up to 4-5 ft, are expected. In recent years, ring nets have been increasingly used for slope protection (drapery), mostly outside North America, to control large-sized rockfall. Because of the reported high strength of ring nets and the need to examine cost-competitive alternatives to cable nets, WSDOT proposed to evaluate ring nets for slope protection on a Federally-funded rockfall mitigation project. As outlined in the work plan submitted to FHWA, the study includes an evaluation of the ring net installation and an annual assessment of the performance for a 5-year period. This end-of-construction report documents the installation of the ring nets
Retrofit of rectangular bridge columns using CFRP wrapping ( Book )
2 editions published in 2008 in English and held by 6 libraries worldwide
This study investigated retrofitting measures for improving the seismic performance of rectangular columns in existing bridges. Experimental tests were conducted on 0.4-scale column specimens which incorporated details that were selected to represent deficiencies present in older bridges in Washington State. Two unretrofitted specimens were tested to examine the performance of the as-built columns incorporating lap splices at the base of the columns and deficient transverse reinforcement. Five columns were retrofitted with carbon fiber reinforced polymer (CFRP) composite wrapping and one specimen was retrofitted with a steel jacket. The specimens were subjected to increasing levels of cycled lateral displacements under constant axial load. Specimen performance was evaluated based on failure mode, displacement ductility capacity and hysteretic behavior. For retrofitting of rectangular columns, it is recommended that oval-shaped jackets be used whenever possible
Use of the maturity method in accelerated PCCP construction : contract 6473, I-5, 36th St. vic. to SR-542 PCCP rehab., contract 6886, I-5, James Street vicinity to Olive Way contract 6916, I-205, SR-500 to I-5 PCCP rehab. and dowel bar retrofit ( Book )
2 editions published in 2009 in English and held by 6 libraries worldwide
This report describes the maturity concept and its application on three case studies on actual construction projects. The three were all paving projects in the state of Washington, one a complete rebuild of a section of I-5 in downtown Seattle, and the other two panel replacements, one on I-5 in Bellingham and the other on I-205 in Vancouver. The study found that maturity is a useful tool for determining the strength of the pavement and allowing early opening of the roadway to traffic
Evaluation of warm mix asphalt : contract 7419, I-90 west of George Paving, MP 137.82 to 148.45 ( Book )
2 editions published in 2009 in English and held by 6 libraries worldwide
This report provides details of the construction of a warm mix asphalt (WMA) test section on Interstate 90 in Washington State. The test section consists of 7,813 tons of hot mix asphalt (HMA) and 4,724 tons of WMA produced using Sasobit®. Placement of the WMA used the same equipment and procedures as the HMA and attained the same level of density. Temperature reductions of 30-50°F were achieved using Sasobit®. A final report detailing the performance of the HMA will be prepared five years after completion of the construction
De-bonding of hot mix asphalt pavements in Washington State : an initial investigation by Stephen T Muench( Book )
2 editions published in 2008 in English and held by 6 libraries worldwide
Recent evidence in Washington State indicates that de-bonding of HMA surface layers may become a significant problem. De-bonding describes a condition where adjacent layers of HMA lose adhesion to one another and can become separated. Typically, design and construction practice is to build in a certain amount of bonding, however the appropriate amount, testing and techniques are still under debate. For WSDOT pavements, which are generally thick and long-lasting, this de-bonding is thought to be more prevalent between the surface layer (usually applied as a preservation overlay) and underlying layers. This de-bonding may contribute to early failure of the HMA pavement surface layer, which can increase pavement preservation costs. This study gathers initial evidence on debonding in Washington State and attempts to define the problem scope and potential performance impacts. Specifically it attempts (1) determine if de-bonding occurs, (2) identify possible de-bonding mechanisms, (3) define the scope of de-bonding in WSDOT pavements, (4) determine de-bonding impacts on pavement performance, and (5) identify the role of tack coats in de-bonding
ITS evaluation framework--phase 2 by Peter M Briglia( Book )
2 editions published in 2009 in English and held by 6 libraries worldwide
This report documents the results of applying a previously developed, standardized approach for evaluating advanced traveler information systems (ATIS) projects to a much more diverse group of 16 intelligent transportation systems (ITS) projects. The evaluation approach used structured interviews to investigate technical, management and organizational lessons learned. The approach appeared to work well with this diverse group of projects. This report also includes the individual evaluation reports for the 16 ITS projects that were evaluated. Each report includes a discussion on background information, project description, ITS architecture and standards, system usage and benefits and institutional and technical issues
Evaluation of liquefaction hazards in Washington State by Steven Lawrence Kramer( Book )
2 editions published in 2008 in English and held by 4 libraries worldwide
This report describes the results of a detailed investigation of improved procedures for evaluation of liquefaction hazards in Washington State, and describes the development and use of a computer program, WSliq, that allows rapid and convenient performance of improved analyses. The report introduces performance-based earthquake engineering (PBEE) concepts to liquefaction hazard evaluation. PBEE procedures have been developed and implemented for evaluation of liquefaction potential, lateral spreading displacement, and post-liquefaction settlement. A new model for estimation of the residual strength of liquefied soil was also developed. The WSliq code was developed to have broad capabilities for evaluation of liquefaction susceptibility, liquefaction potential, and the effects of liquefaction. It provides new methods for dealing with the magnitude-dependence inherent in current procedures, and makes the common "magnitude selection" problem moot via a new multiple-scenario approach and through the use of PBEE procedures
Evaluation of long-term pavement performance and noise characteristics of the next generation concrete surface ( Book )
2 editions published in 2011 in English and held by 1 library worldwide
This report documents the construction of the first Next Generation Concrete Surface (NGCS) by the Washington State Department of Transportation (WSDOT). A 1,500 foot test section was installed on the eastbound lanes of I-82 near Sunnyside, WA in October of 2010. Baseline measurements of noise, friction, wear and smoothness are reported. The sound intensity levels of 101.6 and 99.6 for the outside and inside lanes, respectively, are within the range reported for other NGCS projects. A literature review is provided that documents the development of the NGCS process as well as descriptions and results from the initial field trials in the U.S
Use of a double chip seal to correct a flushing hot-mix asphalt pavement in Washington State ( Book )
2 editions published in 2011 in English and held by 1 library worldwide
A chip seal constructed on an existing flushed roadway has the potential to result in bleeding or flushing of the new chip seal. The excess binder, if not properly accounted for during design and construction, will migrate to the surface of the chip seal and fill the aggregate void spaces leaving a flushed surface. The Washington State Department of Transportation (WSDOT) elected to construct a double chip seal to mitigate a flushing section of pavement on SR 20. This report documents the design and construction of the double chip seal and provides information on its initial performance. The double chip seal will be monitored for up to five years at which a final report will be prepared including conclusions as to its success or failure
Quantifying incident-induced travel delays on freeways using traffic sensor data by Yinhai Wang( Book )
3 editions published between 2010 and 2011 in English and held by 1 library worldwide
To quantify incident-induced delay (IID) over a regional freeway network using existing traffic sensor measurements, a new approach for IID estimation was developed in this study. This new approach combines a modified deterministic queuing diagram with short-term traffic flow forecasting techniques to overcome the limitation of the zero vehicle-length assumption in the traditional deterministic queuing theory. A remarkable advantage with this new approach over most other methods is that it uses only volume data from traffic detectors to compute IID and hence is easy to apply. Verification with the video-extracted ground truth IID data found that the IID estimation errors with the new approach were within 6 percent for the two incident cases studied
Studded tire wear resistance of PCC pavements with special mix designs contract 6620, I-90, Argonne Road to Sullivan Road, MP 286.91 to 292.38 ( file )
1 edition published in 2011 in English and held by 0 libraries worldwide
The performance of portland cement concrete mixes with higher flexural strength, higher cement content, and with Hard-Cem additive, carpet drag finish, and tined finish were evaluated over a period of five years to determine their resistance to studded tire wear. None of the pavements with special mixes or, mixes with Hard-Cem additive were more resistant to studded tire wear than conventional pavement with a 650 psi flexural strength mix design. The wear resistance of the pavement could not be correlated to either the method used to finish the concrete or the concrete's flexural strength. Finally, the carpet drag finishing method produced a pavement with acceptable friction resistance
