Livestock Yard — Road-Base-Ready Surface
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.

How to Prepare Subgrade for Road Base
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.
Read the complete How to Prepare Subgrade for Road Base guideRoad-Base Preparation
Road-base preparation controls a specified aggregate layer, not ordinary topsoil. Even distribution and the right shape help the compaction and surfacing operations that follow.
Before moving material
Confirm aggregate type, accepted subgrade and planned layer thickness.
Receiving operation and checks
Compact and complete the project's layer-acceptance checks. Measure levels and thickness at representative locations and transitions.
Do not use a nominal scraper load count as evidence of compacted layer depth.

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.
