Submerged Floating Tunnel: Principle, Features, and Challenges
A submerged floating tunnel (SFT), also called Archimedes bridge or suspended tunnel, is a tunnel that floats in water supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes’ principle). Tunnels in water are not new in civil ...
What are Reclaimed Asphalt Pavement (RAP) Materials?
The Federal Highway Administration (FHA) of the US Department of Transportation (DOT) defines reclaimed asphalt pavement (RAP) materials as removed and/or reprocessed pavement materials that contain asphalt and aggregates. RAP materials are either milled or crushed and used for various ...
Transverse Joints in Asphalt Pavement
Transverse joints are formed either at the beginning or the endpoint of an asphalt pavement and are perpendicular to the direction of the pavement. Transverse joints are unavoidable at some point of pavement construction due to unexpected working conditions. But ...
How to Construct Longitudinal Joints in Asphalt Pavement?
Longitudinal joints are joints formed during hot mix asphalt (HMA) pavement construction. These joints are formed when a new lane of hot mix asphalt pavement is placed adjacent to a previously placed lane. An improperly constructed longitudinal joint forms the ...
Heliports: Types and Construction Features
Heliports are landing pads designed for helicopters and powered lift aircraft. They are constructed either from steel, concrete, or aluminum. Heliports are constructed on the roofs of skyscrapers, private buildings, hospitals, golf courses, and other places where helicopters are commonly ...
Different Types of Asphalt Pavements in Construction
Asphalt is the most versatile pavement material used in the construction industry. Asphalt pavement is made of aggregates, sand, additives, and asphalt and is laid for the construction of driveways, parking lots, roadways, etc. Based on the variations in asphalt ...
What is the Difference between Bridge and Box Culvert?
It may appear that bridge and culvert structures are similar as they both serve the vital need of transportation. However, they are very different in aspects like structural design, construction, components, load-carrying capacity, costs, etc. Culvert is defined as a ...
