Book Application of Roller Compacted Concrete in Colorado s Roadways

Download or read book Application of Roller Compacted Concrete in Colorado s Roadways written by and published by . This book was released on 2012 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roller Compacted Concrete (RCC) is a no-slump concrete mixture that is transported, placed, and compacted with the same construction equipment as asphalt pavement. RCCs were used to construct three sections of pavement in Weld County Road 28 (WCR 28), eastbound of State Highway (EB 66), and westbound of State Highway (WB 66). Three sets of field inspections were conducted: 1) during construction; 2) nine months after construction; and 3) two years after construction. Strength and durability behaviors of the RCCs were tested right after construction, and some of the material properties of the RCCs were further tested nine months after construction. Field inspections showed that the diamond ground surface texture of EB 66 and WB 66 is better and smoother than the surface of WCR 28 where large cracks and chipping occurred along both longitudinal and transverse directions. The relatively poor quality of RCC samples at WCR 28C location may be due to the different quality of concrete mix, the degree of compaction used during construction, and the absence of saw cut joints. The concrete specimens were tested for rapid chloride permeability, drying shrinkage, freeze-thaw resistance, compressive strength, splitting tensile strength, and flexural strength. The test results obtained after the construction indicated that the chloride permeabilities are in the low to very low ranges, the drying shrinkages are in the normal range, and freeze-thaw resistance is fine. The compressive strength, splitting tensile strength, and flexural strength are also in the normal range similar to that of conventional concrete. The test results obtained nine months after the construction indicated that deteriorations occurred in the RCC concretes. After only nine months of service, the RCCs already showed noticeable changes in all of the selected properties tested. More tests and field inspections should be conducted in the future after a longer monitoring period to verify and validate the initial findings observed in the material properties and surface conditions of the RCC pavements.

Book Investigation of Roller Compacted Concrete for Use in Pavements in Virginia

Download or read book Investigation of Roller Compacted Concrete for Use in Pavements in Virginia written by M. Shabbir Hossain and published by . 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.

Book Guide for Roller compacted Concrete Pavements

Download or read book Guide for Roller compacted Concrete Pavements written by Dale S. Harrington and published by . This book was released on 2010 with total page 104 pages. 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.

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 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.

Book An Investigation of the Frost Resistance of Air Entrained and Nonair Entrained Roller Compacted Concrete RCC Mixtures for Pavement Applications

Download or read book An Investigation of the Frost Resistance of Air Entrained and Nonair Entrained Roller Compacted Concrete RCC Mixtures for Pavement Applications written by Steven A. Ragan and published by . This book was released on 1990 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete (RCC) pavement use a paving technique in which a zero-slump portland cement concrete mixture is placed using asphalt concrete pavers and compacted with vibratory and rubber-tired rollers. A reason for using RCC pavements is its durability in freezing and thawing conditions. Conventional concrete pavements are air-entrained for protection in freezing and thawing conditions. However, attempts to air-entrain RCC mixtures have met with little success. Nonair-entrained RCC has performed well in freezing and thawing field conditions in the past, but laboratory samples have demonstrated poor frost resistance. Objectives of this study are: (a) to determine if a proper air-void system can be entrained in RCC pavement mixtures using various dosage rates and aggregate gradings, and (b) to evaluate frost resistance and investigate material, construction, and site conditions which might influence the frost resistance. Results of the study demonstrated that various RCC mixtures may be entrained with air voids sufficient to protect the concrete from frost damage. RCC may also be effectively air-entrained in field applications. Studies of selected sites have shown that nonair-entrained RCC pavements have performed well in freezing and thawing climates.
