A median in a road is an area that separates incoming traffic from traffic going in the same direction. Road median is commonly used where there are separate lanes traveling in opposite directions. So, the road median converts a “two-way” movement into a “one-way” movement. It also acts as an area for cars to U-turn … Read more
Rutting in flexible pavement is creation of a depression or a groove. It is typically shown as wheel path engraved on the road surface. The main cause of rutting failure is the deformation of the asphalt concrete under the loading from vehicles. In cold climate areas, rutting happens as snow studded tires travel in a … Read more
No matter the type of road, drainage is an integral part of the design process. Be it a highway or a link road, the surface runoff is always there. Sometimes the highway engineer provides slope in the profile of the road to drain the surface water. But in some cases, the slope is not sufficient … Read more
Surveying is preliminary divided into plane surveying and geodetic surveying on the basis of considering earth surface as a spherical or plane. But there’re more differences between plane and geodetic surveying so let’s explore some of these: Different types of surveying Survey is the art of determining relative position of object on the surface of … Read more
It is one of the most widely used soil compactors used by contractors and builders worldwide. The sheepsfoot roller is a piece of heavy self-propelled equipment usually mowed and runs in a static position. Depending on the character of the soils, this sort of roller is available in several sizes. It is one of the … Read more
So, when you step in the world of pavements, you’ve got two broad classes or types’ i.e. rigid pavement and flexible pavement. So, what is rigid pavement and what is the difference between flexible and rigid pavement? In simple terms, we can say that a pavement made with concrete acts like a rigid pavement while … Read more
Breast Walls are constructed to protect freshly cut slope on a steep hillside embankment from rolling down the hill due to adverse weather conditions, such as land erosion and sliding. In hilly areas, the hillside gradients and slicing slopes can affect the road’s sturdiness. During rainfall you can’t travel in hilly areas that have small slips … Read more
Camber in road construction is an elevated road surface at the median part in comparison to the edges. It is a cross-slope from the diagonal direction and civil engineers design this camber in roads and highways. Camber is provided in road to remove or drain rain water and surface runoff from the pavement as quickly … Read more
