How are stockpiles recommended to be "constructed"?

The recommended method for constructing stockpiles in the context of Hot Mix Asphalt (HMA) involves using power equipment. This approach ensures that the material is handled efficiently and effectively, allowing for the creation of stable and accessible stockpiles. Power equipment helps in achieving a consistent shape and density in the stockpile, which is crucial for maintaining the quality of the asphalt mix.

Using power equipment facilitates the rapid placement of large quantities of material, reduces labor costs, and minimizes the risk of material segregation. Additionally, it allows for better control over the stockpile's height and slope, which are important for effective material drainage and to prevent issues like segregation or contamination.

While other methods may seem viable, they do not provide the same level of efficiency and consistency needed for HMA stockpile construction. Hand placement may lead to inconsistent compaction and material distribution, and reliance solely on gravity might result in poorly shaped stockpiles that could affect the quality of the asphalt. Manual compaction may be impractical for larger quantities and can be labor-intensive, making it less efficient than using power equipment.
