Road Shoulder — Crossfall
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Incorrect Crossfall
Crossfall controls the change in level across a road, path or other surface. A correct centreline does not prove that the edges drain correctly.
Before moving material
Measure the cross-section at the affected location.
Receiving operation and checks
Check the corrected section and the neighbouring transition sections. Verify both edges and any gutter or drain connection.
Do not infer a road crossfall specification from a generic illustration.

Road corrugations concern both the wearing material and traffic interaction. Dragging loose peaks into hollows can improve appearance temporarily while leaving the cause unchanged.
Before moving material
Assess aggregate condition, drainage and the depth of the corrugated layer.
Receiving operation and checks
Compact and manage traffic as required by the road-maintenance plan. Check that the profile and edge drainage are restored.
Persistent corrugation may need material or maintenance-method changes.

Before road base is placed, the subgrade should be accepted for both level and condition. An uneven or weak supporting surface can lead to thickness variation and premature failure above it.
Before moving material
Confirm formation level and identify unaccepted areas.
Receiving operation and checks
Inspect and accept before spreading base aggregate. Record level and material checks for the same work area.
Adding more base material is not automatically a remedy for weak subgrade.
