CONSTRUCTING A MOTORWAY (CIVIL ENGINEERING PROJECT) Introduction A motorway can be defined roughly as a main road or highway, with two or more lanes on opposite direction, and where fast motor traffic occurs. A motorway has to be well constructed with all the required plans, materials and skilful engineering needed to provide a long-lasting use for motorists.
First, the planners used geographic and topographic maps. Although technology and computers were not yet very effective at that time, the information the planners had was enough to make them achieve their great objective. Present planners and engineers have all the information from computers and databases before they embark on such a gargantuan task. The vision that the planners had is mastery itself, considering that in the nineteenth century, motor vehicles were just beginning to be invented. Engineers and builders of motorways are faced with multiple and complicated tasks. In the initial steps, they are concerned particularly of the volumes of earth to be moved during embankments and cuttings. There is also the concern of the cost of moving those volumes of earth. Present engineers try to balance these two activities – the cut and fill. The aim is to avoid borrow or spoil, which adds costs to construction. Formation of cutting and embankments Cuts and embankments are needed in constructing a motorway or an elevated highway. ...
