Evaluation of long-term pavement performance and noise characteristics of the next generation concrete surface( )

3 editions published between 2011 and 2014 in English and held by 16 WorldCat member libraries 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
Evaluation of Portland cement concrete pavement with high slag content cement : contract 7064, SR-543, I-5 to international boundary widening, MP 0.20 to MP 1.09( )

2 editions published in 2009 in English and held by 13 WorldCat member libraries worldwide

The performance of a section of concrete pavement built with 30% Ground Granulated Blast Furnace Slag (GGBFS) is compared to a control section of concrete pavement built with 25% GGBFS to determine if the higher slag content pavement is more resistant to wear from studded tires. This report details the construction of the pavement, construction quality control tests, and initial base line wear, friction, and smoothness results
Interpretation of geotechnical properties of cement treated soils by Balasingam Muhunthan( Book )

2 editions published in 2008 in English and held by 12 WorldCat member 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 12 WorldCat member 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
Evaluation of dowel bar retrofit for long-term pavement life in Washington State by Linda M Pierce( Book )

2 editions published in 2009 in English and held by 12 WorldCat member libraries worldwide

The outcomes of this study include guidelines for dowel bar retrofit project selection and construction best practices, a summary of dowel bar retrofit performance in Washington State, and estimated dowel bar retrofit project costs
Evaluation of liquefaction hazards in Washington State by Steven Lawrence Kramer( )

2 editions published in 2008 in English and held by 12 WorldCat member 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
Retrofit of rectangular bridge columns using CFRP wrapping( )

2 editions published in 2008 in English and held by 11 WorldCat member 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
ITS evaluation framework-- phase 2 continuation (2009) : seventeen projects by Peter M Briglia( )

2 editions published in 2009 in English and held by 11 WorldCat member libraries worldwide

This report documents the results of applying a previously developed, standardized approach for evaluating intelligent transportation systems (ITS) projects to 17 ITS earmark projects. The evaluation approach was based on a questionnaire to investigate technical, management, and organizational lessons learned. The report includes 15 evaluation reports for the 17 ITS projects. Each report includes a discussion of the following: Background; Project description; System usage and benefits; Cost, operations and maintenance; Architecture and standards; and Lessons learned. Most of the lessons learned in this evaluation phase were similar to those documented in previous evaluations
In-service evaluation of major urban arterials with landscaped medians--phase II( Book )

2 editions published in 2009 in English and held by 11 WorldCat member libraries worldwide

An initial study of the effects of placing trees in medians was conducted by comparing three years of before and after data for several roadway sections on SR 99 in the city of SeaTac. These results were published in February 2007 in the WSDOT research report "In-Service Evaluation of Major Urban Arterials with Landscaped Medians-Conditions as of 2004," WA-RD 636.1 (St. Martin, et al, 2007). This second phase of the study continues the evaluation of major urban arterials with landscaped medians
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 11 WorldCat member 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
De-bonding of hot mix asphalt pavements in Washington State : an initial investigation by Stephen T Muench( )

2 editions published in 2008 in English and held by 11 WorldCat member 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
Use of a double chip seal to correct a flushing hot-mix asphalt pavement in Washington State( )

2 editions published in 2011 in English and held by 11 WorldCat member libraries 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
Dowel bar retrofit-- do's and don'ts by Linda M Pierce( Book )

2 editions published in 2009 in English and held by 10 WorldCat member libraries worldwide

This updated report documents construction and inspection guidelines for the successful construction of a dowel bar retrofit project. Original project report published in 2003 (WA-RD 576.1)
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( )

1 edition published in 2011 in English and held by 10 WorldCat member 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
Use of ring nets for slope protection for rockfall : end-of-construction report( Book )

2 editions published in 2009 in English and held by 10 WorldCat member 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

Quantifying incident-induced travel delays on freeways using traffic sensor data. final research report by Yinhai Wang( )

2 editions published in 2011 in English and held by 10 WorldCat member libraries 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
Combined aggregate gradation as a method for mitigating studded tire wear on PCCP : contract 5947, I-90, Sprague Avenue Interchange phase 3, MP 284.41 to 286.38 by Keith W Anderson( Book )

2 editions published in 2009 in English and held by 10 WorldCat member libraries worldwide

Two sections of pavement were built with different specifications for the gradation of the aggregates, one with the standard gap-graded aggregate specification and one with a combined gradation specification. Equal wear rates for both sections indicated that the combined aggregate gradation had no positive affect on the pavement's resistance to studded tire wear
Performance analysis of centerline rumble strips in Washington State( )

1 edition published in 2011 in English and held by 10 WorldCat member libraries worldwide

With a goal of reducing collisions, the Washington State Department of Transportation implemented policy for installing centerline rumble strips on undivided highways and invested in funding strategies for those installations in 2006. There have been some limited studies on the effectiveness of those installations, but a more complete study is appropriate. Most of the previous analysis has been focused on the types of collisions that rumble strips were intended to reduce: specifically, centerline crossovers. Other collision types, such as run-off-the-road-to-the-right, have not been adequately explored previously to determine whether their frequencies have changed. The effectiveness of rumble strips on targeted collision types also needs to be reviewed to determine whether there are any site characteristics that influence effectiveness. This study evaluates the effectiveness of centerline rumble strips under a variety of traffic and geometric conditions. The findings will result in better guidance on when to use rumble strips to address various collision types
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 10 WorldCat member 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
