Modern road construction involves the removal of geographic obstacles, and the use of new construction materials that are far more improved and durable.
Rock and earth is removed by explosion or digging.
Embankments, tunnels, and bridges are constructed and then vegetation is removed by deforestation – if necessary. Finally, the pavement material is laid by using a range of road construction equipment. Roadways are basically designed and constructed for use by vehicles and pedestrians. Storm drainage and ecological considerations should be considered seriously. Sediments and erosion are controlled to avoid damaging effects. Drainage systems are constructed so that they should be able to carry waste water to a waterway, stream, river, or the sea.
Earthwork is one of the major works involved in road construction. The process includes excavation, material removal, filling, compaction, and construction. Moisture content is controlled, and compaction is done according to standard design procedures.
Normally, rock explosion at the road bed is not encouraged. While filling a depression to reach the road level, the original bed is flattened after the removal of the topsoil. The fill layer is distributed and compacted to the designed specifications.
This procedure is repeated until the compaction desired is reached. The fill material should not contain organic elements, and possess a low index of plasticity. Fill material can include gravel and decomposed rocks of a particular size.The road surface finish is reliant on the economic aspects, and the estimated usage.
Safe designing of roads, highway space management and proper drainage of water are major aspects that Navi Professional Consulting engineers are well versed in.
Owing to our vast experience in construction and project management – defining project objectives, dividing the project into modules and optimising the available resources is an effortless task.
