    The drums vibrate horizontally (oscillate) or vertically (vibrate), thus significantly increasing the effect of compaction. The operation is completed by a final roller pass that will “iron out” any remaining irregularities in the asphalt pavement or surface to produce a

  • Compacting Hot-Mix Asphalt Pavements: Part I | Roads

    a hot-mix asphalt (HMA) pavement is the density of the mix that is achieved by the contractor at the time of construction. The density of a material is defined as the weight of the material, which occupies a certain volume of space. The compaction process causes the asphalt-concrete mix to be compressed and its volume reduced.

  • Factors affecting asphalt compaction | Asphalt magazine

    Compaction is the process of densifying, or reducing the volume of, a mass of material. Most practitioners consider achieving appropriate compaction critical to the performance of an asphalt pavement.

  • How to Compact Asphalt Pavements - For Construction

    So the paving industry relies on compaction to increase pavement density to extend pavement life. As a result of the compaction process, the asphalt-coated aggregate particles in the mix are forced closer together, which increases the amount of aggregate interlock and interparticle friction and also reduces the air void content of the mix.
