Civil Engineering Simplified
Camber in roads is the slope or angle built into the road surface, typically seen on curved or sloped sections of the road. This slope is designed to provide several benefits, including improved drainage, enhanced vehicle stability, and better driver visibility. The purpose of camber on roads is to ensure safe and comfortable driving conditions for motorists.

Bitumen for roads is an important topic to understand when it comes to road construction. Bitumen is used in road construction because of the wide range of features and advantages it possesses over other pavement construction materials. The significance of bitumen in the construction of roads will be demonstrated in this article. In addition, we shall see bitumen road layers, various bituminous materials, cutback bitumen, bitumen grade, and bitumen properties.

Highway engineering is an important topic in civil engineering. It includes the study of roads in depth. The technical aspects involved in this subject plays a significant role in construction of different types of roads. In this blog, I will show you all the details of the subject including the definition, topics, importance etc.

The bitumen softening Point Test is done to determine the consistency of bitumen. Bitumen is a viscoelastic material, which means it behaves like both a liquid and a solid state. It does not have a specific melting point. As the temperature increases, the bitumen becomes softer and the viscosity of the bitumen decreases. One of the common parameters for classifying bitumen is the softening point of the bitumen. This property shows at what temperature the bitumen softens.

The penetration test for bitumen is a laboratory method for grading bitumen based on its hardness. In this test, the amount of penetrating a specific needle into the bitumen is measured.
More than 85% of bitumen is used in road construction. Weather condition affects on bitumen binder. In cold weather, bitumen becomes hard, and the possibility of cracking increases. On the other hand, hot weather causes bitumen becomes soft and sticky.

A cloverleaf interchange is a two-level interchange at which left turns are done by ramp roads (reverse directions in left-driving regions) (US: ramps, UK: slip roads). Vehicles first proceed to go left (in right-hand traffic) as one lane crosses over or below the other, then exit right onto a one-way three-fourth loop ramp (270 °)

Smart roads and other smart road technologies are relevant to the advancement of the transportation sector of a country. We are going to dig deep into this in the upcoming sections. We’ve all learned about connected vehicles, self-driving cars, GPS mapping, applications for route optimization and ride-hailing services, after all

Types of road construction is signigicant to understand about the category of roads and their characterestics. In this blog, we will find out the details of 5 types in detail. Rubblization is a more complete fracturing of the old, worn-out concrete that essentially turns the old pavement into a new asphalt road aggregate base. The hypothesis is that regular small cracks disperse thermal stress over a wider area than uncommon large joints, minimising the strain on the asphalt pavement overlying it.
