Structural Engineering Evolution - History, Present, and Future Structural engineering is a branch of civil engineering that deals with the design, construction, and maintenance of structures such as buildings, bridges, towers, and other infrastructure. It involves analyzing the forces acting on a structure and determining how to make it withstand these forces while also ensuring it is safe, functional, and aesthetically pleasing. History of Structural Engineering The history of structural engineering can be traced back to ancient civilizations such as the Egyptians, Greeks, and Romans, who constructed impressive structures using primitive materials such as wood, stone, and mud. The development of iron and steel in the 19th century revolutionized structural engineering, enabling the construction of taller, larger, and more complex structures. The present scenario of Structural Engineering In the present scenario, structural engineering is a rapidly growing field, thanks to ad

Methodology for the Construction of Bituminous Road Works The construction of Bituminous Road Works in India is governed by the Indian Standards and guidelines provided by the Ministry of Road Transport and Highways (MoRTH). Here is a general methodology to be followed for the construction of Bituminous Road Works as per Indian Standards: Subgrade Preparation: The subgrade is prepared by excavating the soil and removing any debris or organic material. It is then compacted to achieve the required density and level. The subgrade should have a minimum CBR (California Bearing Ratio) of 2% for rural roads and 5% for urban roads. Granular Sub-Base (GSB):  The GSB layer is constructed on top of the subgrade to provide a stable base for the bituminous layer. The GSB layer is typically 200-300 mm thick and consists of crushed stone or gravel. The material is compacted to achieve the required density and level. Bituminous Concrete (BC) Layer:  The bituminous layer is constructed on top of
