What formula is used to determine HMA placement yield?

The formula used to determine HMA (Hot Mix Asphalt) placement yield involves dividing the total amount of asphalt used by the area that it covers. This calculation provides a yield measurement that expresses how effectively the material is being utilized in the paving operation.

When using the formula Amount used (lbs) / area covered (sq yd), the result is a yield in pounds per square yard, which is a standard measurement in asphalt paving. It allows for the assessment of whether the correct amount of material is being applied for the intended coverage, ensuring that the installation meets specifications and achieving proper thickness and performance of the asphalt layer.

The focus on the correct units (pounds and square yards) is crucial in this context, as it reflects the typical practices and units used in the industry for evaluating paving operations.
