Aggregate Properties and the Performance of Superpave

CONSENSUS AGGREGATE PROPERTIES The Superpave method includes four consensus aggregate properties: coarse aggre- gate angularity, flat and elongated particles, uncompacted voids in fine aggregate, and sand equivalent. The consensus properties were to

Aggregate Properties and the Performance of Superpave

Increased particle index value or uncompacted voids in coarse aggregate also provide increased rutting resistance. The latter combine the effect of shape, angularity, and texture. â ¢ The current Superpave specification levels for coarse aggregate angularity have been adopted by 39% of the agencies that specify ASTM D5821 or an equivalent.

MATERIAL SPECIFICATION FOR AGGREGATES HOT MIX

Coarse aggregate for Superpave 12.5FC 2 may be obtained from a different source than the fine aggregate. When RAP is used in Superpave 12.5FC 2, the coarse aggregate portion of the RAP may be derived from different sources. In all other cases, blending of coarse aggregates for Superpave 12.5FC 2 from different sources shall not be permitted.

Flat and Elongated Particles Pavement Interactive

Overview. The flat and elongated particle test is used to determine the dimensional ratios for aggregate particles of specific sieve sizes. This characterization is used in the Superpave specification to identify aggregate that may have a tendency to impede compaction or have difficulty meeting VMA specifications due to aggregate degradation.

COARSE- VERSUS FINE-GRADED SUPERPAVE MIXTURES:

Both coarse- and fine-graded hot-mix asphalt mixtures can be designed within the gradation control points recommended in Superpave (Registered trademark) mix design. Some states have begun to specify only coarse-graded mixtures (below the restricted zone), whereas other states are specifying only fine-graded mixtures (above the restricted zone).
