The interaction of materials, construction, and the environment makes projections of pavement performance difficult. To increase the confidence with which these projections can be made, a simplified statistical quality control plan for airfield pavement materials and and construction was developed. By the application of statistics, a relatively small number of randomly collected samples can be used to evaluate the quality of materials and construction. Test results based on a specific number of samples can be extended wth the desired confidence limits based on probability theory to evaluate an entire lot of material. This statistical quality control plan evaluates pavement quality much better than do conventional specifications. It also describes how to handle materials or construction of borderline acceptability. When test results indicate that material or construction meets the desired quality, it is accepted at 100 percent payment; when it fails to meet the minimum requirements, it is rejected. When material or construction is found to be below the desired quality but above the minimum requirements, the job is paid for at a reduced cost. The evaluation is done on a day-to-day basis so that the engineer and the contractor know the acceptability of the job as it progresses. /Author/
