Sulphur in Roads

Patented Shell Thiopave technologies have been developed to help road construction companies and road owners to improve road performance through innovative use of sulphur in the asphalt mixture.

Shell’s sulphur enhancement technologies enable a proportion of the bitumen in the asphalt mixture to be replaced with Shell Thiopave, resulting in a stronger mixture that enhances the load bearing capacity of the finished road.

Shell Thiopave has significant potential to increase road life and, importantly, to deliver meaningful reductions in greenhouse gas emissions through lower temperature production. At the same time, it reduces the amount of bitumen needed for road construction, by replacing a proportion of the bitumen in the asphalt mixture, therefore helping to alleviate industry concerns about bitumen supply/demand imbalances.
