* Flexible Pavement Construction
Subgrade
The subgrade is the natural soil prepared, leveled, and properly compacted. It forms the foundation of the pavement system.

Sub-Base Course
A layer of selected granular material is placed over the subgrade and compacted. It provides additional support and helps distribute traffic loads.
Base Course
The base course consists of well-graded crushed aggregate. It provides major structural support and distributes wheel loads safely to the lower layers.
4
Tack Coat
A thin layer of bitumen emulsion is sprayed between asphalt layers. It acts as a bonding agent and ensures proper adhesion between the courses.
Binder Course
The binder course is a hot-mix asphalt layer placed above the base. It provides structural strength and helps transfer traffic loads.
Surface Course
The surface course is the final hot-mix asphalt or wearing layer.
It provides a smooth, durable surface suitable for traffic and protects the underlying pavement layers.
Compaction
Each pavement layer must be properly compacted using suitable rollers to achieve the required density, stability, and durability.

Quality Control
Before opening the road to traffic, engineers should verify

A learning from my work in road and highway design.
This typical cross section includes:
• RCC Box
• Pavement layers - PQC, DLC & GSB
• 2.5% cross slope
• Crash barriers
• Drainage arrangement
• Service roads
Working on practical drawings helps me improve my understanding of Civil 3D and Transportation Engineering.

The image highlights essential software used in civil engineering for design, analysis, project management, and visualization. It includes AutoCAD for 2D and 3D drafting, Revit for Building Information Modeling (BIM), and Civil 3D for infrastructure and road design. STAAD.Pro, ETABS, SAP2000, and SAFE are widely used for structural analysis and foundation design. Tekla Structures supports steel detailing and fabrication. Primavera P6 and MS Project help with project planning, scheduling, and resource management. ArcGIS is used for mapping and spatial analysis, while HEC-RAS and SWMM are important for hydraulic and stormwater modeling. MATLAB is useful for numerical analysis and engineering computations. SketchUp is mainly used for 3D modeling and visualization. However, the image incorrectly labels SketchUp as a geotechnical analysis tool; software like PLAXIS or GeoStudio is actually used for geotechnical engineering. Overall, the infographic provides a useful overview of key civil engineering software.
