A new type of asphalt mixture, which is composed of very rough texture for road surface similar to that of porous pavement, as well as the same functions as stone mastic asphalt for inside was developed. For evaluation of surface texture and waterproof, laboratory specimen was fabricated using roller compactor, which is expected to give similar compaction in field. Then those key properties from the evaluation were successfully reflected into conventional items of Marshall Stability Test for standardization of this mixture. Since it is important to fabricate laboratory specimen with properties similar to those in field, volumetric design method needs to be studied for such a new conceptual asphalt pavement in the future. |
