Evaluation of hot mix asphalt(HMA) properties compacted at various temperatures

Hot mix asphalt (HMA) mixture compacted at various temperature has always been a concern to researcher. Compaction below the standard compaction temperature may bring reverse effect on HMA properties. Moisture damage of HMA with low temperature referred as striping and this problem become prevalent...

Tensile strength ratio (TSR) for mixes compacted above 115ÂºC is more than 80% and this shown that mix still stable at minimum temperature of 115ÂºC for ACW14. ACW20 has TSR more than 80% when compacted at 130ÂºC and above. This suggests that as mixes get coarser the minimum compaction should be higher. For Marshall Stability, the result indicates that as the compaction temperature increases, the stability increase. However for compaction temperature above 145ÂºC, the stability slightly drops.
