Abstract
Waterproofing system in the pavement structures is one of most important functions to keep concrete slab durability, and waterproof material on concrete slab is required to have the sufficient mechanical properties for the wheel load to keep waterproofing function. To be based on concept of performance-based design method, it is important to evaluate mechanical properties of waterproof layer for the wheel load. In this paper, it was directed attention to creep characteristics of waterproof layer and creep characteristics of waterproof layer was estimated by the combination of experimental data, FEM analysis and a Genetic Algorithm metod. The mechanical behavior of waterproof layer applied the wheel load with running and braking was analyzed by FEM with both creep material model and estimated modulus model.
