Choosing the right project topic is one of the most important decisions a civil engineering student makes during their academic career. Transportation and highway engineering offers a particularly rich field of study because it directly affects how people and goods move through the built environment. From pavement design to intelligent transport systems, the scope for […]
What Is Stone Mastic Asphalt? Understanding Its Composition and Structure Stone Mastic Asphalt, commonly abbreviated as SMA, is a specialized hot mix asphalt designed to deliver high performance under heavy traffic loads. Developed in Germany during the 1960s and widely adopted across Europe, SMA has proven itself on heavily trafficked roads where durability and rut
When Hurricane Ian struck southwest Florida in September 2022, it destroyed the Sanibel Causeway, the only road link connecting Sanibel Island to the mainland. The rebuilding of the Sanibel Causeway after Hurricane Ian became one of the most significant emergency infrastructure projects in recent American history. Florida-based contractors Superior Construction and The de Moya Group,
The completion of the $666 million Interstate 35-E (I-35E) Southern Gateway project in Dallas, Texas, represents a landmark achievement in modern highway construction and major infrastructure redevelopment project delivery. Led by Fluor Corporation in joint venture with Balfour Beatty Infrastructure for the Texas Department of Transportation (TXDOT), this 10-mile corridor reconstruction demonstrates how design-build project
The $161-million Terminal F expansion and renovation at Philadelphia International Airport (PHL) stands as a significant example of how architectural glass can transform a transportation hub. Completed in 2018, the project added a 34,000-square-foot baggage claim building, a reconfigured security screening checkpoint, a secure-side passenger corridor, and an expanded central hub. Designed by The Sheward
Road Safety Engineering Road safety audits are systematic examinations of roadway projects to identify potential safety issues. The audit is conducted by an independent team of safety specialists who review the project plans and field conditions. The audit identifies the safety concerns and recommends design modifications to reduce crash risk. The crash analysis uses historical
Infrastructure Asset Management Infrastructure asset management is a systematic process for maintaining, upgrading, and operating physical assets such as roads, bridges, water systems, and public buildings cost-effectively. The asset management approach recognizes that infrastructure assets have a life cycle cost that extends beyond the initial construction cost. The asset inventory database records the location, type,
Traffic Impact Studies Traffic impact studies evaluate the potential effects of proposed developments on the surrounding transportation network and identify improvements needed to maintain acceptable traffic operations. The study is typically required by local jurisdictions as part of the development approval process for projects that generate significant traffic. The study scope is determined through consultation
Asphalt Pavement Design and Construction Asphalt pavements are the most common type of roadway surface in the United States, covering over 90 percent of the paved road network. The asphalt pavement structure consists of multiple layers including the asphalt surface course, the base course, and the subbase course, each designed to distribute traffic loads to
Geographic Information Systems in Civil Engineering Geographic Information Systems are computer-based tools for capturing, storing, analyzing, and displaying spatially referenced data. GIS technology has become an essential tool in civil engineering for applications including site selection, environmental impact assessment, infrastructure planning, and transportation network analysis. The GIS database stores spatial data as points, lines, and
