In highway construction, the process of adjusting roadway layers is known as?

In highway construction, the process of adjusting roadway layers is referred to as balancing. This term specifically relates to the technique of ensuring that the construction materials are appropriately distributed across the grading site to achieve the desired elevation and cross-section of the road. This process involves the careful planning and distribution of earth materials, which may include cutting (removing earth) and filling (adding earth) to achieve a smooth and level gradient suitable for vehicle safety and water drainage.

Balancing is crucial because it helps to manage the earthwork efficiently, reducing the need for excessive import or export of materials, and minimizing construction costs and environmental impact. Proper balancing leads to a stable foundation for the road, allowing for a better and longer-lasting pavement structure.

While trimming, leveling, and compact filling are also important processes in roadway construction, they refer to specific actions rather than the overall process of adjusting and balancing the layers of the road. Trimming usually refers to removing excess material, leveling indicates making a surface even, and compact filling focuses on compressing material to enhance stability. Each of these is a part of the overall balancing process, but they do not encompass the complete scope of adjusting roadway layers as does the term "balancing."
