What is a primary advantage of using aggregate in landscaping?

Using aggregate in landscaping primarily serves as an economic surfacing material. Aggregates, such as gravel or stone, tend to be relatively inexpensive compared to other surfacing options like concrete or pavers. This cost-effectiveness makes them an attractive choice for both large-scale and small landscaping projects, allowing for budget-conscious decisions while still providing functional and aesthetically pleasing surfaces.

While aggregates do require minimal maintenance, making them a low-maintenance option, this benefit is secondary to their economic advantages. Their ability to provide proper drainage and their resistance to weed growth are also notable characteristics, but these do not directly address the question of primary advantage. Additionally, while aggregates can be designed to meet ADA compliance, this is not guaranteed and can depend on specific installation and material choices. Thus, the foremost advantage lies in their economic viability for landscaping applications.
