FIELD VALIDATION OF STATISTICALLY-BASED ACCEPTANCE PLAN FOR BITUMINOUS AIRPORT PAVEMENTS. VOLUME 1. CORRELATION ANALYSIS OF MARSHALL PROPERTIES OF LABORATORY-COMPACTED SPECIMENS
The laboratory phase of a three phase research effort conducted to field validate a multiple price adjustment system for bituminous airport pavements using the Marshall properties, stability, flow and air voids, is presented. The prupose of the laboratory phase was to identify whether correlations exist among the Marshall properties within individual tests. To consider the use of these properties in a multiple price adjustment system, it was first necessary to identify these correlations. The experimental design consisted of 4 different aggregate gradations and 6 different asphalt contents for a total of 24 combinations. A total of 12 replicates were tested for each combination for a total of 288 Marshall test specimens. A number of statistical analyses were conducted on the laboratory test results. An analysis of variance was conducted to determne whether time, i.e., order of testing, had an effect on the results. Correlation coefficients among the Marshall properties, i.e., stability with flow, stability with air voids and flow with air voids, were calculated for each of the 24 combinations. The results of the analysis indicate correlations that are consistent enough to violate an assumption of statistical independence among the properties. The results indicate that the effect of correlations among the properties should be taken into consideration in developing a multiple price adjustment approach based on the Marshall properties.
