Modification of Residual Bitumen from Orhovytska Oil by Butonal Polymeric Latexes

Abstract

Modification of residual bitumen from Orhovytska oil by Butonal polymeric latexes has been studied. Using such modifiers the softening temperature and bitumen elasticity increase and penetration decreases. The commercial paving bitumen may be produced from the residuals using Butonal polymeric latexes.

Polymer modified bitumen

“…Synthetic latex of ButonalNS type (BASF, Germany) [38][39][40][41] and thermopolymers of Elvaloy series (DuPont, USA) [4,15,42] are widely used. These polymers not only reduce bitumen sensitivity to temperature changes, but also enhance the cohesive and adhesive strength resulting in the increase of strength and crack resistance of asphalt concrete pavement.…”

Polymer Modified Bitumen: Review

“…Synthetic latex of Butonal NS type (BASF, Germany) [41][42][43][44] and thermopolymers of Elvaloy series (DuPont, USA) [7,18,45] are widely used. These polymers not only reduce bitumen sensitivity to temperature changes, but also enhance the cohesive and adhesive strength resulting in the increase of strength and crack resistance of asphalt concrete pavement.…”

Study on Rheological Properties of Extra-Heavy Crude Oil from Fields of Ukraine

“…Since high-viscosity oil has a low content of gasoline and diesel fractions and a high content of heavy fuel oil with high pour point, such oil is not desirable to be processed under a traditional refinery scheme. However, it is a good raw material for the production of bitumen which has not to be modified further, compared with bitumen produced from conventional oil [11][12][13][14]. Usually the modification increases the bitumen cost and complicates the production scheme.…”
