asphalt road 3d model

A technical 3D CAD cross-section model of a civil engineering asphalt road. The model features a detailed 2-lane roadway bounded by concrete curbs and pedestrian sidewalks on both sides. The cutaway view clearly displays the engineered pavement layers with realistic materials and distinct thicknesses: top dark gray asphalt wearing course, asphalt binder course, a well-graded crushed stone base course, and a compacted subbase soil layer. High-detail textures for asphalt, concrete, and soil aggregates. Clean industrial design, explicit layer separation, isometric perspective view, studio lighting, isolated on a dark gray background.
