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 0 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 Evaluation of Criteria for Uniformity of Roller compacted Concrete

Download or read book Evaluation of Criteria for Uniformity of Roller compacted Concrete written by Brian H. Green and published by . This book was released on 1998 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a laboratory investigation that was conducted for the purpose of validating mixer- uniformity requirements for roller-compacted concrete. The purpose of the investigation was to verify existing guidance or, if necessary, recommend changes to existing guidance. The investigation included both air-entrained and nonair-entrained concrete. The results indicate that existing guidance is appropriate for Vebe consistency, water content, coarse aggregate content, compressive strength, and air-content determinations. However, the results indicated that existing guidance could he too restrictive for the unit weight of air-free mortar determinations. A recommendation was made to consider revising current guidance on the allowable range for unit weight of air-free mortar.

Book Strength and Density of Laboratory Prepared RCC Specimens

Download or read book Strength and Density of Laboratory Prepared RCC Specimens written by SA. Shihata and published by . This book was released on 2000 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Appropriate compaction is essential in producing roller-compacted concrete (RCC). An experimental program was conducted to study the effect of compaction on the strength and den-sity of RCC specimens. Compaction was achieved by tamping the sample with a hammer similar to that of ASTM D 1557. The main variables were the magnitude of compaction energy, number of lay-ers per mold, and cement content. The compaction energy ranged from 300 to 2700 kN-m/m3. The test results show that the decrease of the unit weight by 7.7% decreases the compressive and splitting tensile strengths by 73 and 71%, respectively. Increasing the cement content compensates for the reduction in compaction energy. The average degree of compaction of the cores taken from the field RCC test slabs was 99% of the unit weight of field samples prepared with a 2700 kN-m/m3 compaction energy.
