High Resistance Polymermodified Binders to Secure ... - Nynas

In the table 1 is shown the tender specification in comparison to the new developed
high resistance PmB – Nypol 25 HR. Typical applications for Nypol 25 HR are heavy
duty industrial areas such as port unloading areas, container terminals or traffic areas
with high static loading such as truck parks and bus stations. Nypol 25 HR is used in
stone mastic asphalt, asphalt concrete and asphalt binder course for extraordinary
loading.
Furthermore you can see the properties of the high resistance PmB Nypol 45 HR
which was developed for the application of asphalt mixtures for heavy duty traffic
areas such as road class up to SV, junction areas, roundabouts, traffic jam areas,
bus stations, high gradient roads, etc.
2.4.1 Performance Testing of High Resistance (HR) PmB
For the behaviour at low temperatures the stiffness at -16 °C [Mpa] was measured by
using the Bending Beam Rheometer (BBR) in the style of the description of
AASHTO TP1-97. The Force Ductility (FD) at 25 °C was measured in the style of the
description of TL PmB – Appendix B. For the deformation behaviour the Complex
Sheer Modulus G* and the Phase Angle δ was measured at 60 °C by using the
Dynamic Sheer Rheometer (DSR) in the style of the description of AASHTO TP1-97
with the test conditions as follows:
Frequency: 1,59 Hz
Plate Diameter: 25 mm
Plate Gap: 1 mm
Deformation: 0,05 mm
Temperature Control: Water Bath
The heat stability amounts more than double measured by complex shear modulus
and compared with a standard PmB. The behaviour at low temperatures is not
affected measured with the Bending Beam Rheometer.
