Book Description
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.

Book Description
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 Description
The performance of CRCP has revealed a number of failure modes that are traceable to design, construction, materials, and maintenance deficiencies and such other factors as environemntal conditions and traffic loadings. This report of the Transportation Research Board includes a review of the cumulative experiences of state that have constructed and maintained CRCP. Guidelines for repair techniques are included, and areas of needed research are identified.
