Definition: Semiasphaltic is a type of asphalt that has a slightly lower density than conventional asphalt, but still provides the same level of protection and durability as traditional asphalt. It is typically used in low-traffic areas or for less demanding applications such as parking lots and driveways. In terms of its characteristics, semiasphaltic asphalt can have a higher viscosity (i.e., it has a lower density) than conventional asphalt, which makes it more suitable for use on roads with high traffic loads.
