Design Pavement and Substructure Layers for Tramway Infrastructure

Hi

I am currently seeking a reliable and recognized methodology for designing the pavement and substructure layers of a tramway system. The objective is to ensure adequate load-bearing capacity, durability, and long-term performance of the trackbed, particularly in an urban context where the tramway often shares space with road traffic.

If you could provide any guidance, standards, or references regarding the structural design of tramway trackbeds—including the dimensioning of the pavement and underlying layers—I would greatly appreciate it.

Thank you in advance for your assistance.
