FIELD AND LABORATORY INVESTIGATION OF EXPERIMENTAL PAVEMENT USING LOW QUALITY AGGREGATES

This study was initiated to investigate the effects of low quality aggregates on pavement performance parameters. The results of this research generally confirm that the presence of deleterious materials in either the fine or coarse aggregate can be detrimental to pavement performance; and simulated freeze and thaw conditioning causes significant loss of mixture strength and deterioration in mixture performance. This investigation evaluated the field and laboratory performance of an experimental pavement constructed with materials having various levels of deleterious aggregates. The major conclusions of this study can be summarized as follows: (1) The results of environmental conditioning conducted on both field cores and laboratory compacted samples showed a significant dependence upon aggregate type. All three mixture types showed significant reduction in modulus of resilience and indirect tensile strength, for both field cores and laboratory samples. (2) While this investigation focused mainly on the effects of deleterious materials in coarse aggregate, the results suggest that the presence of deleterious materials in the fine aggregate can be as detrimental to mixture performance. /Author/
