 # A truck, such as a flowboy or spreader, is used to place the aggregate on the shoulder. Following behind the trucks is a grader, which shapes the aggregate shoulder to the desired dimensions. A vibratory roller compacts the aggregate once it is graded out.

 ==== Trenching ====
 A cold mill machine can be used to remove the existing surface to the plan dimensions. The milling is loaded directly into a truck and removed from the site. If required, an excavator with a ditching bucket or grader with a shoe follows the mill to clean up the trench. At times, a grader with a shoe fully trenches the shoulder. Depending on the width of the trench, either a vibratory roller or plate compactor compacts the existing grade.

 For a hot mix asphalt (HMA) overlay project, aggregate shoulders should be installed flush with the new HMA pavement. If less than 3 inches of material is being placed, the existing aggregate shoulder must be scarified to a minimum depth of 2 inches prior to placement of new material. The compacted aggregate should be maintained flush with the existing pavement surface.

 Aggregate shoulders should be placed in a way which does not damage the adjacent pavement. The cross slope of the aggregate shoulder should be verified after compaction to ensure plan requirements are met and proper drainage is achieved. The width and depth should meet the plan requirements with the finished layer thickness after compaction within ±1/2-inch of the plan. The final grade must have positive drainage or meet the cross slope on the plans and must not create ponded areas.

 === Aggregate Approaches ===
 Similar to aggregate shoulders, aggregate approaches require the subbase or existing grade to be accepted prior to placement. The grade must not be frozen, soft, rutted, or generally unstable. Aggregate being used should be verified to ensure it meets the class requirements.
