SLIDE 3

Innovative binder additivation

 PmBs

– PmB + Sasobit – New crosslinking (oil extract, silicon

xide)

– Maleic anhydride grafted recycled polyethylene treated by irradiation

 Rheology modifier

– Replacement for oxidized bitumen blocks – Packed bitumen for road applications

 PPA: reduction of bitumen oxidative aging:

SLIDE 4

Innovative binder additivation

 Biomass

– Biobitumen with vegetable oil – Use of lignin – Biochars – Cashew nut shell oil as antiox

 Nanotechnologies

– Graphite nanoplates – Nanoclays

SLIDE 5

Bitumen quality

 Composition: Evaluation of waxy bitumen  Process:

– Change in bitumen quality during working stages / Storage

 Specifications:

– Performance specifications – R-value, Glover-Rowe param. – Characteristic viscosity – Rheology parameter (T(G*=15kPa)

 Binder and asphalt prop. relation.

SLIDE 6

New development in bitumen testing - chemometrics
