Dec 28, 2000 · 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.

Unlike hot-mix, spray seal is formed by applying a spray coat of bitumen over a prepared base then laying an even spread of aggregate on top. Spray seal can be applied in a single or double coat. It’s important that the base for the spray seal is well-prepared, since it’s thinner than hot-mix and will closely follow the shape of the base.
