2.1.12 Anti-stripping agent
Such fillers as surface active agent or lime, cement, etc. added into asphalt or asphalt concrete mixture with a view to improving aggregate and asphalt adhesiveness and strengthening the water damage resistance of asphalt concrete mixture.
2.1.13 Asphalt concrete
Asphalt concrete mixture that meets the requirements of technical standards and is formed by mixing coarse aggregate, fine aggregate and filler that meet the specified gradation with asphalt and then conducting compaction by rolling (expressed as AC).
2.1.14 Dense aggregate asphalt concrete
Asphalt concrete made by mixing mineral aggregate, of which particles in various sizes are consecutively graded and densely extruded, with asphalt and then compacting until the residual voidage less than 6%.
