Book Use of Roller Compacted Concrete Pavement in Stafford Virginia

Download or read book Use of Roller Compacted Concrete Pavement in Stafford Virginia written by and published by . This book was released on 2015 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete (RCC) is a relatively stiffer hydraulic cement concrete mixture than regular concrete when fresh. Similar to regular concrete, RCC is a mixture of aggregate, cementitious materials, and water, but it is placed using asphalt pavers and compacted by vibratory rollers, and it hardens into concrete. RCC contains a low amount of water, exhibits no slump, and requires asphalt paving equipment for placement rather than expensive slip-form paving equipment. It does not contain reinforcement, tie-bars, or dowels. RCC can be placed and opened to traffic in a short period of time. All of these factors combined make it a relatively low-cost material for roadways compared to asphalt or conventional concrete pavements. However, RCC may lack the smoothness required for high-speed roadways and can undergo raveling and/or cracking; an asphalt overlay may remedy the smoothness and raveling issues. Although cracks might occur in the RCC and potentially reflect through the asphalt layer, such cracks should stay tight because of the low shrinkage of RCC. A composite pavement with RCC and an asphalt overlay has the potential to be a cost-effective long-lasting pavement system. The purpose of this study was to document the construction procedures and provide lessons learned for a RCC project recently completed by the Virginia Department of Transportation that covered about 134,000 ft2, equivalent to 2 lane-miles, at the Park & Ride lot in Stafford County, Virginia. About one-third of the RCC was used to rehabilitate the existing Staffordboro Boulevard (Route 684). The mixture used had 15% fly ash to provide improved durability and sustainability. Batches of the RCC mixture fluctuated in moisture content, and delays in placement sometimes occurred that also resulted in wet and dry mixtures. The compaction, surface smoothness, and road profile were affected by the fluctuations in moisture content. RCC cylinders prepared using a vibratory hammer usually exceeded compressive strengths of 1,600 psi and 4,000 psi at 12 hours and 28 days, respectively. Only a few early cracks were observed in the pavement. Opening to traffic at an early age for a section, i.e., within 5 to 6 hours of placement, did not result in any visual damage to the pavement; most sections were opened in less than 48 hours. RCC overlaid with 2 in of asphalt is performing well after two winters and 18 months of traffic for one section and after one winter and 8 months of traffic for the rest. Based on the observations in this study, for successful construction of RCC, proper compaction and mixing equipment are essential. Achieving the proper level of compaction in the field is key to attaining quality RCC. To avoid early cracks, joints need to be cut deeper than one-fourth depth of the pavement and continuous curing is essential. A continuous paving operation is needed to avoid unplanned and poor-performing cold joints. The Virginia Department of Transportation should consider RCC in future field trials, particularly for applications where fast construction of rigid (concrete) or composite pavement is needed.

Book Concrete Pavement Design Construction and Performance Second Edition

Download or read book Concrete Pavement Design Construction and Performance Second Edition written by Norbert J. Delatte and published by CRC Press. This book was released on 2014-05-22 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of Concrete Pavement Design, Construction, and Performance provides a solid foundation for pavement engineers seeking relevant and applicable design and construction instruction. It relies on general principles instead of specific ones, and incorporates illustrative case studies and prime design examples to highlight the material. It presents a thorough understanding of materials selection, mixture proportioning, design and detailing, drainage, construction techniques, and pavement performance. It also offers insight into the theoretical framework underlying commonly used design procedures as well as the limits of the applicability of the procedures. All chapters have been updated to reflect recent developments, including some alternative and emerging design technologies that improve sustainability. What’s New in the Second Edition: The second edition of this book contains a new chapter on sustainability, and coverage of mechanistic-empirical design and pervious concrete pavements. RCC pavements are now given a new chapter. The text also expands the industrial pavement design chapter. Outlines alternatives for concrete pavement solutions Identifies desired performance and behavior parameters Establishes appropriate materials and desired concrete proportions Presents steps for translating the design into a durable facility The book highlights significant innovations such as one is two-lift concrete pavements, precast concrete pavement systems, RCC pavement, interlocking concrete pavers, thin concrete pavement design, and pervious concrete. This text also addresses pavement management, maintenance, rehabilitation, and overlays.

Book Concrete Pavement Design Construction and Performance

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2018-10-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.

Book Application of Roller Compacted Concrete RCC Technology to Roadway Paving Construction Productivity Advancement Research CPAR Program

Download or read book Application of Roller Compacted Concrete RCC Technology to Roadway Paving Construction Productivity Advancement Research CPAR Program written by and published by . This book was released on 1994 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to investigate the performance of a roller-compacted concrete (RCC) pavement for use as a high-speed surface. A test section consisting of a small parking lot and a two-lane roadway was constructed. During construction, three major parameters were varied: paver speed, rolling amount, and joint spacing. The paver speed was varied to determine what effect, if any, this has on average lay-down density, average final density, rideability, skid resistance, load transfer, and density profiles. The average lay-down and final densities of the RCC pavement were determined using a nuclear density device, which determined the density of various depths throughout the pavement. The load transfer was determined at transverse joints and transverse cracks by using falling weight deflectometer data. The rolling amount was varied to determine its effect on all of the same properties as paver speed except lay-down density. The joint spacing was varied to examine an optimum spacing that would not develop intermediate cracking and would provide the desired rideability and load transfer. From this project, it was determined that no adjustments in paver speed, rolling (types of patterns), or joint spacing will significantly enhance RCC pavement properties so that it may be used for high-speed applications.
