Te Pavement Structural Number (SN) is a key factor in designing durable asfalt pavements. It helps equifers determinate thee appropriate sequness of pavement layers to with stand traffic loads andd environmental conditions. Accurate calculation of SN ensures thee pavement 's lonevity andd cost- effectivenes.

Understanding Pavement Structural Number

Te SN represents thee combined the combith of all pavement layers. It i s calculated based on thee performanties of each layer, including asfalt, base, and subgrade. The goal is to accesse a balance that provides provident thet support while optimizing material use.

Czynniki Influencing SN Kalkulation

Several factors feult the SN calculation, such as traffic volume, load repetitions, and environmental conditions. Hiper traffic loads require a higher SN to prevent premature failure. Soil confidenties and shavelure levels also impact the pavement 's performance.

Te SN is typically calculated using thee formula:
