Effect of Type of Compaction on Mechanical Properties in Warm-Mix Asphalts
This paper compares the effect of type of compaction (impact and gyratory compaction) on mechanical properties (such as water sensitivity and stiffness modulus) in warm-mix asphalts. Moreover, the manufacture and laying temperatures and the use of additives for warm-mix asphalts have been taken into account. The mixes tested have a semidense aggregate gradation with a B-60/70 penetration binder and different types of warm-mix additives have been added. The mixtures compacted by gyratory compactor at different temperatures all displayed good behavior in terms of water sensitivity; in contrast, not all mixtures compacted by impact achieved this. On reducing the manufacturing temperature, the stiffness moduli decreased in all mixtures for both types of compaction, this reduction being less pronounced in the mixes manufactured with the gyratory compactor. The results have been evaluated statistically.
