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
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.
