What is a common use for Asphalt Treated Permeable Base (ATPB)?

Asphalt Treated Permeable Base (ATPB) is primarily utilized to serve as a drainage layer in various construction projects. The permeability of ATPB allows for the effective management of stormwater and groundwater, helping to prevent the accumulation of water that can lead to structural issues or surface flooding. This functionality is particularly important in mitigating the effects of heavy rainfall or snowmelt.

The drainage capacity of ATPB makes it advantageous for applications in road construction and parking lots, where proper water management is essential for maintaining surface stability and integrity. By allowing water to drain through the layer rather than pooling on the surface, ATPB contributes to improved pavement performance and longevity.

While other options present possible characteristics or benefits of materials used in construction, they do not encapsulate the primary function of ATPB in the same way that its role as a drainage layer does. This specific functionality is integral to the design and performance of pavement structures that incorporate ATPB.
