Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete (RCC) is an economical, fast-construction candidate for many pavement applications. It has traditionally been used for pavements carrying heavy loads in low-speed areas because of its relatively coarse surface. However, in recent years its use has expanded into commercial areas and local streets and highways. This guide provides owner-agencies, contractors, material suppliers, and others with a thorough introduction to RCC and its many applications. Based on current research and best practices, the guide provides detailed overviews of RCC properties and materials, mixture proportioning, structural design, and production and construction considerations, plus troubleshooting guidelines and an extensive reference list for more comprehensive information.

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2007-09-12 with total page 389 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.

This book was released on 1986 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete pavement (RCCP) provides a lower-quality, economical alternative to slipform and fixed-form concrete pavements. It is ideally suited for areas where heavy, low speed vehicles such as tanks or container handlers are the primary users of the pavement. RCCP is constructed by placing a zero-slump portland cement concrete mixture with an asphalt paver and compacting it with several passes of a vibratory roller. By using this construction method, wherein large quantities of concrete can be placed quickly with a minimal amount of labor and equipment, savings of 30 percent over conventional concrete paving methods have been reached. The final RCCP surface is not as smooth as a conventionally constructed concrete pavement, and the surface texture resembles that of an asphaltic concrete pavement surface. Quality control and assurance consist of testing materials going into the concrete, checking the plant calibration regularly, measuring the in situ density of RCCP using a nuclear density gage, checking the smoothness of the finished RCCP with a straight edge, and taking cores to check the pavement strength, density, and thickness. Inspectors at the plant and on the jobsite are vital to ensure that a quality RCCP is being built.

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.

This book was released on 2016 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete (RCC) is a stiff mixture of aggregate, cementitious materials, and water with zero slump. RCC is consolidated or compacted in the fresh state by use of a roller with or without vibration. RCC typically is placed with asphalt paving equipment in thicknesses of 4 to 8 in for pavement application. RCC has gained the attention of the paving industry in recent years because of its history of low cost, rapid construction, and durable performance. The Virginia Transportation Research Council conducted this laboratory study to gain familiarity with RCC technology and to develop guidelines for its use in the field. RCC mixtures were successfully produced in the laboratory using locally available materials, and their properties were measured. These mixtures achieved compressive strengths around 5,000 psi in 28 days and had properties similar to those of conventional concrete in terms of compressive strength, modulus of elasticity, modulus of rupture, and splitting tensile strength. A special provision was developed and used in the two field projects. The special provision was subsequently modified based on the field experience and is provided in the Appendix. VDOT should implement the RCC specification developed in this study for regular VDOT use of RCC. Use of RCC should be considered in future field applications, particularly where fast construction of rigid (concrete) pavement is needed; an example of such an area would carry heavily loaded, slow-moving vehicles such as at intersections and access roads to truck or bus parking areas. VDOT should annually monitor the long-term performance of the two constructed RCC projects reviewed in this study over a period of at least 10 years. Evaluations should document joint efficiencies for load transfer (through testing with the falling weight deflectometer), any visual evidence of deterioration of asphalt at joints, and any other general signs of pavement distress that may occur.
