Day-to-Day Responsibilities
Study traffic volume, axle loads and design life to decide the pavement type and thickness for a road.
Choose flexible (bituminous) or rigid (cement concrete) pavement and design each layer from the sub-base to the surface course.
Check sub-grade soil strength, compaction and moisture, since every layer above depends on it.
Plan drainage for surface and subsurface water, and design protection where frost-susceptible soils are present.
Review mix designs and test results for bitumen, aggregates and concrete, and approve material quality on site.
Supervise the laying of tack coats, binder courses and surface courses, and check levels, smoothness and compaction.
Carry out condition surveys of existing roads and plan repairs, resurfacing and maintenance to keep them safe.
