Abstract: Asphalt pavements of bus lane, roundabout and industrial area are heavy loaded by high
shear and high static vertical loads. For these pavement areas, by using of special bitumen
with high viscosity (PmB 10/40-65 NV), high stable asphalt mix can be produced. But it is
not always possible to purchase and storage this bitumen at mixing plant. The technical
aspect of this paper is production of high-stable asphalt mix by using available bitumen and
equipment at asphalt mixing plant. Therefore, high asphalt mixes DAsphalt® D HS with
several polymers are developed. As binders, high polymer modified bitumen PmB 10/40-70
A have to be produced by using the bitumen PmB 25/55-55 A and polymer granular
(Plastomer). The gained test results of bitumen produced meet the requirement of the high
viscosity bitumen (PmB 10/40-65 NV) according to European Standard EN 14023. The
findings of the DAsphalt® D HS show higher rutting, stiffness and lower temperature
sensitivity compared to the reference asphalt variant produced with high viscosity bitumen
PmB 10/40-65 NV. By means of ranking of investigated variants, two additives have been
selected to place on test field of Construction Company STRABAG S.E. The gained test
results show good workability, compatibility and confirm the finding of the laboratory
