Highway design is the cornerstone of civil engineering, combining geometry, materials science, and traffic analysis to shape the arteries of commerce and travel. Poorly designed roads can lead to safety hazards, inefficient traffic flow, and costly maintenance. This course equips you with the essential tools and principles needed to tackle these challenges, enabling you to design highways that are not only functional but also resilient and cost-effective.  

Over this course, you will learn about highway design: 

1. Geometric Design: Dive into the principles of horizontal and vertical alignment, including curves, grades, and sight distances, to create safe and efficient road layouts.

2. Equivalent Single Axle Load (ESAL): Understand how traffic loads impact pavement performance and learn to calculate ESALs, incorporating truck factors and growth projections.

3. Flexible Pavement Design: Explore the design of layered road systems, from surface courses to subgrades, using the AASHTO Structural Number (SN) method.

4. Rigid Pavement Design: Learn the design principles for concrete pavements, including JPCP, JRCP, and CRCP, and apply the AASHTO rigid pavement design equation.

5. Earthworks: Master the calculation of cut and fill volumes, mass haul diagrams, and optimization strategies for efficient material movement and cost savings.

6. Drainage and Material Behavior: Understand soil shrinkage after compaction and the impact of water on pavement performance to ensure long-lasting infrastructure.

By the end of this course, you will:

1. Design both flexible and rigid pavements tailored to traffic and environmental conditions.

2. Calculate earthwork volumes, balance material movement, and optimize costs.

3. Incorporate ESALs into your pavement designs to ensure long-term performance.

4. Use mass haul diagrams and balance points to manage construction resources effectively.

5. Apply geometric design principles to create roads that prioritize safety and efficiency.

Whether you’re an aspiring highway designer, a civil engineering student, or a professional looking to sharpen your skills, this course will prepare you to take on real-world challenges. Imagine being the engineer who not only designs safe and efficient highways but also ensures their longevity through meticulous planning and innovation.
