The project aims to represent the composition and logic of long-life pavement to support valid design variants, consistency checking, and parametric thickness\/material analysis in digital twin environments.<\/p>\n\n\n\n
Scope:<\/strong> Intended Users & Intended Use:<\/strong><\/p>\n\n\n\n Users: Pavement engineers, transportation researchers, and digital-twin design teams.<\/p>\n\n\n\n Use: Knowledge representation and reasoning to ensure structural completeness and support “what-if” material changes.<\/p>\n\n\n\n Figure01: <\/strong>Perpetual pavement built up of layered stack and surface-renewal concept<\/p>\n\n\n\n The hierarchy follows a physical decomposition modeled after the engineering stack.

The scope is fixed around the physical and functional aspects of the HMA (Hot Mix Asphalt) layers, Surface, Intermediate\/Binder, and Fatigue-Resistant Bottom, as well as the supporting foundation (Subbase and Subgrade).<\/p>\n\n\n\n![\"\"](\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2026\/02\/image-41.png\")
