Hi, Concrete pavements are rigid pavements having very high flexural strength (rigidity) as compared to the flexible pavements. They  can be constructed using two different methods: Alternate Bay method Continuous bay method In alternate bay method, concrete pavement slab are laid on whole width of pavement in alternate bays. In continuous bay method, concrete pavement slabs […]

Hi, One of the main studies of Traffic Engineering is the study of road user Characteristics. Before going into that, the question arises, what is Traffic Engineering!? As per the book Highway Engineering, by S K Khanna & C E Justo, ‘Traffic Engineering is the branch of engineering which deals with the improvement of the

Hi,  In this post we have put  the details and engineering behind the length of the Summit Curves required for the vertical alignment of the highways. Please feel free to put your reviews or doubts in the comment box at the end of the post. Thanks! Read: Length of the Transition Curves Length of Summit

Hi,Grade or Gradient is the ratio of vertical rise or fall of the road center line with respect to its length. It has to be provided for the vertical alignment of the road. When we provide gradient to the road, vehicle has to apply more power to overcome the component of the gravity force. Higher the

Hi, today I am going to share with you the steps which are necessary for the construction of the earth roads. General : First of all what is an earth road? Earth road is a type of road whose whole pavement section is constructed with the locally available earth material preferably. Borrow pits are located at

Hi, There are various types of compaction equipment: Rollers Rammer Vibrators a. Rollers: Rollers are vastly used in the highway construction for compacting the subgrade and other layers. They are again of three types: Smooth wheeled roller (Image source:Google images) Smooth wheeled rollers: These are used for compacting granular soils and specially useful where crushing is required.

Hi, how you doing? Today I am going to post here what I learnt about the highway construction equipment.As we know that highway construction at field can be broadly classified into two phases: Excavation or preparation of sub-grade. Pavement layers construction. In the phase of the excavation or preparation of the sub-grade we need two types

Hi,How you doing? Let’s discuss the design of the dowel bars. So, what are dowel bars first? Dowel bars Dowel bars are steel bars, generally round in shape, and are used in the expansion joints which, are provided in the concrete pavements(rigid pavements) to allow the expansion of the concrete slab.The main function of the

Hi, We know that penetration test is one of the important tests, which is performed to test the grade of the Bitumen. You might be looking this article to jot down the theory and procedure of the test into your laboratory/practical notebook or might be checking just to refresh your knowledge. If you have one
