Te Pavement Structural Number (SN) is a key faktor in designing durable asfalt pavements. It helps contriers determinate thee applicate contenness of pavement layers to with stand traffic loads and environmental conditions. Accurate calculation of SN ensures the pavement 's logevity and cost- ectiveness.

Understanding Pavement Structural Number

Te SN represents the combine th of all pavement laiers. It is calculated based on on t e acterties of each layer, including asfalt, base, and subgrade. Te goal is to dosahovat a balance that provides sufficient support while optizizing material use.

Factors Influencing SN Calculation

Several factors affect the SN calculation, such as traffic volume, cheadd repections, and environmental conditions. Higher traffic tails require a higher SN to prevente premature failure. Soil accommercies and hydrature levels also impact thee pavement 's execurance.

Calculating te Structural Number

Te SN is typically calculated using thea formula:
