Abstract

Asphalt concrete due to both of its high technological and service properties is a choice one material for road pavement construction. As asphalt concrete contains bitumen as a binding material it becomes vulnerable to the destructive effect of the fuels and lubricants. This disadvantage is very critical in places like airports, parking lots and car service centers. Polymer modified asphalt (PMA) concrete is considered to be more resistant to fuel than the traditional asphalt concrete.

In this study, changes in fuel resistance index were investigated for asphalt concrete and PMA concrete samples under simultaneous action of bending force and diesel fuel. The influence of bituminous binders consistency and technology of modification of bitumen by SBS polymer on fuel resistance of asphalt concrete and PMA concrete were analyzed.

Our research has found that bitumen modified with direct introduction of SBS polymer has a much higher fuel resistance than pure bitumen of similar consistency. On the other hand, modification of bitumen by mixing it with polymer-oil solution results in a significant drop of PMA concrete fuel resistance.
