Evaluation of laboratory procedures for compacting asphalt-aggregate mixtures Sousa, JB et al

Av: Utgivningsinformation: Washington DC Strategic Highway Research Program, 1991; SHRP-A/UWP-91-523, Beskrivning: 176 s. + bilÄmnen: Onlineresurser: Bibl.nr: VTI P1393:523Location: Abstrakt: Examines three compaction methods: Texas gyratory, kneading, and rolling wheel compaction. Unlike static and impact compactors, these compactors subject the densifying mixture to shearing motions similar to those induced during field compaction. Differences among the compaction methods are greatest for mixtures with low air voids, presumably because pore pressures are larger when there are fewer air voids in the mixture. Depending on their design and operation, compactors within a given genre may produce specimens having quite different engineering properties.
