COMPACTIBILITY AS A CLASSIFICATION FOR ASPHALT MIXES? TRANSIT LINE

DIE VERDICHTBARKEIT ALS KLASSIFIZIERUNG FFUUERR ASPHALTMISCHGUT?

A compaction function is derived with which the actual state of compaction corresponding to the degree of consolidation of bituminous mixes may be determined. The universal compaction parameter contained in the equation indicates which compaction process should be performed in order to achieve a particular degree of consolidation. Mixes which are increasingly difficult to consolidate are characterised by rising parameter values. With the same consolidation parameters it is also possible to describe the relation of the void content to the compaction process. Since there exists a close relationship between compactibility and resistance to deformation of asphalt, it is possible to quantitatively evaluate and classify different mixes by means of their compaction parameters in regard to their deformability. In conclusion, it is shown how the different classes of mixes may be collated according to the characteristics of actual traffic-, climatic- and road conditions. (TRRL)
