HAUL ROAD
Negative Superelevation
Minimum 5% Superelevation Required
Mining Severity
Haul road condition
-
HAUL ROAD
High Speed Corner with negative superelevation. Possibility of
loss of traction on LR.
Centre crown on road. Reduced contact area of outside RR
tyre.
Haul road condition
Mining Severity
-
HAUL ROAD
Severe road rutting. Caused Rear axle to lose contact with
road.
Poor road base stability (i.e. high rolling resistance). Result
of excess water retention.
Haul road condition
Mining Severity
-
HAUL ROAD
Poor haul road drainage. No crossfalls or drains installed
Non-continuous grade. May result in high inertia gear shift
point.
No sheeting material used on haul road.
