Potential Alternative To Styrene Butadiene Styrene For Asphalt B2last is an innovative, low viscosity liquid asphalt modification additive that improves adhesion performance of the asphalt mix. by crosslinking the components within the liquid asphalt, b2last reduces stripping of the aggregates from the binder and leads to a more sustainable, flexible pavement. B2last® is an innovative new low viscosity liquid asphalt modifier from basf. b2last improves the functional properties of asphalt binders, mixes and flexible pavements.
Asphalt Modification Lucobit Aktiengesellschaft This research assesses the effect that two chemical modifiers (thiourea and an isocyanate functionalized castor oil prepolymer) exerts on the bitumen rheology and on the resistance to potential. In this investigation, a novel liquid, low viscous chemical additive (b2last®) is presented for its use in asphalt binders. special emphasis was set on the modification procedure, where two different methods were studied: a batch modification and an in line modification, both on a laboratory level. Basf recently finished preliminary field testing of its new additive, b2last®, a low viscosity liquid asphalt modification additive used to improve adhesion performance of an asphalt mix. By chemically modifying the asphalt binder, basf developed an innovative solution for the paving industry. after nearly four years of field usage and trials in different regions, b2last has proven to be an efficient and cost effective way to modify bitumen.

Paving crews observed that b2last mixes have significantly less build up and less need for release agents than traditional polymers. pavements modified with b2last also see improved compaction over standard polymer modified asphalts. While sbs modified asphalt has some advantages, challenges such as storage stability, aging resistance, cost and performance variability need to be overcome to increase its use in asphalt pavement applications. This modified asphalt solution helps roofing systems last longer, improves operational efficiencies and is compatible with most liquid asphalts. b2last r is ideal for asphalt shingles on sloped roofs, self adherent underlayment and flat, built up roofing. Our present work attempted to compare two different reactive polymer systems with the “classical” system which uses thermoplastic elastomer.
