Statistical Specification Evaluation
A statewide evaluation of test results from Highway Construction Materials was performed. Statistical parameters were determined for physical tests on aggregate base, portland cement concrete, asphalt concrete, and cement treated base. Where possible the current quality levels were compared with prestatistical specification levels. A technique known as the Moving Average was monitored to determine what, if any, differences in materials quality level would result, in conjunction with data collection and analysis. Personal contact was established with over 100 resident engineers and materials' men throughout the state to determine their reactions to, and opinions of, the Moving Average. Although the Moving Average method being researched was not in effect long enough for a definitive evaluation, the results obtained indicated that quality levels have not been adversely affected and further that the personnel who worked with the new method generally were in favor of it.
