A study was made of the influence of consolidation on properties of portland cement concrete. A model acceptance sampling plan for concrete consolidation is proposed. The plan is of the inspection by variables type and requires a sample size of eight per lot. The plan provides for buyer's and seller's risks of 5 percent. The plan was field tested in Idaho and Iowa. Field testing indicated that monitoring concrete pavement consolidation is practical and economically feasible.

Under the Construction Productivity Advancement Research (CPAR) Program, a new two-part system for improving the consolidation of concrete has been developed. First, a new vibratory consolidation subsystem was developed to enhance the efficiency and effectiveness of concrete consolidation in the context of a slipform paver. The system uses the phenomenon of resonance to efficiently vibrate a rigid and relatively large consolidation volume within concrete to relatively high-vibratory displacement amplitudes at a frequency appropriate for concrete consolidation. Dynamic finite element analysis and optimization techniques were used to design a mechanical system based on this concept which also satisfied the geometric requirement for installment in slipform pavers. The vibratory consolidation subsystem was then constructed, evaluated, and subjected to a comparative experimental study which revealed its advantages over conventional internal vibrators. A strain-gauge monitoring system was also devised and evaluated for real-time monitoring of the consolidation process of concrete under the action of the new system. A connection mechanism to interface between the new consolidation system and slipform pavers was devised, manufactured, and installed on a slipform paver. A large-scale field simulation was constructed for the purpose of evaluating the whole connection system under realistic operating conditions that closely simulated those of slipform pavers. Refinement of the hydraulic control and cooling system of the shakers that drive the resonant vibrators is going on currently. This will he followed by long-term longevity and fatigue evaluation of the complete system under realistic operation conditions on a slipform paver. Second, significant progress was made in the development of the other subsystem. It is an electrical impedance device that provides results in rea.

Petrographic examinations of specimens from two recently constructed concrete pavements suggested that complete consolidation of the concrete may not have been achieved. Consequently, a quantitative evaluation of the degree of consolidation in these specimens was undertaken. The pavements were of plain, jointed design with dowels for load transfer. Both projects were constructed using slip-form paving machines with spud vibrators. It was found that the entrapped void content was excessive. In both cases, the entrapped void content of the lower half of the pavement was higher than the upper half. This situation apparently occurred because the vibrators were set to ride above the preplaced dowel assemblages. In one pavement the consolidation of the upper half was adequate, but the entrapped void content of the upper half of the other pavement was also found to be excessive. The following recommendations are made: (1) During preplacement conferences and actual construction, emphasize the importance of adequate consolidation of concrete throughout the pavement, especially in the vicinity of dowel assemblages. (2) Consider alternative methods of dowel placement. Pavers with dowel bar inserters are available. (3) Investigate methods to evaluate and monitor consolidation during construction. Nuclear gauges are used for this purpose in some states although not all applications have been successful. Ultrasonic techniques show promise for this application.
