The effect of road crossfall on road wear caused by heavy vehicles

Author: Steenkamp, Anton J ; Berman, Robert B ; Kemp, Lana ; De Saxe, Christopher C Date: Jul 2019 The paved road network is a critical asset to any economy. South Africa has a paved road network that has an estimated value in excess of R2 trillion. This asset is however under threat as there was a backlog in maintenance of more than R197 ... Read more
Heavy vehicle dynamic road wear from a rigid heavy vehicle when including road crossfall

Author: Steenkamp, Anton J ; Kienhofer, F ; De Saxe, CC Date: Sep 2021 Previous research investigating the dynamic road wear produced by heavy vehicles has not included the effect of road crossfall. This study shows that road crossfall, even at values as low as 1%, has a significant effect on the predicted dynamic ... Read more
Heavy vehicle safety performance

Author: Deiss, J ; Kienhöfer, F ; Nordengen, Paul A ; De Saxe, Christopher C ; Berman, Robert J ; Steenkamp, Anton J Date: Oct 2018 Significant benefits have been realised in South Africa from adopting the PBS framework in the form of reduced fuel consumption, CO2 emissions, road wear, trips and crashes. Three representative baseline PBS vehicles were developed (a quad-axle ... Read more
High capacity vehicles road wear impact in South Africa

Author: Kemp, Lana ; Steenkamp, Anton J ; De Saxe, CC Date: Sep 2021 The substantial road maintenance backlog in South Africa, coupled with an inadequate budget allocation, requires high impact solutions in order to preserve the 158 000 km paved road network. Focussing efforts on the heavy vehicles operating ... Read more
