• Abstract:
  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.
