Highway Construction Company in Bangladesh

Asphalt is a mixture of aggregates, binder and filler, which is used for constructing and maintaining roads, highways and more. Asphalt is ideal for rural highways because of the ease of maintenance and repair. Budgeting for small roadway repairs or patching is much simpler and faster than replacing entire slabs of roadways on less heavily trafficked areas such as country roads. We use best quality asphalt for constructing highways. Asphalt road surfaces have many benefits, including cost efficiency, reduction in noise pollution and comfort. Using asphalt materials in road construction and maintenance can improve the benefits for all road users and the environment. Asphalt is safe, smooth and durable.

Cement concrete is used to construct the highways in case of concrete roads. These are very popular and costlier than all other types of roads. They are not flexible, so they require less maintenance. Concrete roads are suitable for high traffic areas. The main benefit of concrete road construction is the longevity. Lasting 20-40 years on an average, paving in concrete can boast two to four times the lifespan of asphalt. Concrete is recyclable. Once crushed into gravel, concrete can be used in other ways. This sturdy surface is less prone to dips and rutting, meaning it is a favorite for freeway construction. For constructing a highway with concrete, we use high-quality concrete.

Composite materials are frequently used in types of construction that are extra associated to maintenance, recycling, and rehabilitation. Composite materials are mixtures of each asphalt and concrete and are normally employed in one of two methods. They actually positioned asphalt overlays over a broken surface, or the highway may additionally be cracked and seated instead, forming a genuine new surface. Composite highways mix a Portland cement concrete sub-layer with an asphalt overlay. They are typically used to rehabilitate present highways as an alternative than in new construction. Asphalt overlays are once in a while laid over distressed concrete to fix a clean sporting surface. For making any composite highway, you can rely on SIMEX Bangladesh.

There are three normal kinds of construction strategies associated to recycling the surface of distressed or broken pavement. Rabbling, Cold/Hot in-place Recycling, and Full-depth Reclamation. Rubberizing entails decreasing the avenue to gravel and then making use of a new surface, each warm and bloodless in-place recycling depends on the use of bituminous pavement to make stronger the street (at distinct temperatures and admixtures, of course), and Full-depth reclamation includes each complete reduction and the addition of binding dealers or different additives. In addition to the construction cost savings, in-situ recycling also provided substantial environmental benefits including a reduction in carbon dioxide emissions as well as reduced materials transportation and less use of newly extracted materials.

Bituminous roads are widespread roads around the world. They are the most used roads in the world. This road types are low in cost and suitable for driving conditions. The thickness of bituminous roads depends upon the subgrade soil conditions. It generally consists of aggregate spread over sprayed-on asphalt emulsion or cut-back asphalt cement. The aggregate is then embedded into the asphalt by rolling it, typically with a rubber-tired roller. They are most often used in urban areas where the roughness and lose stone associated with chip seals is considered undesirable. For bituminous highway construction you can contact with SIMEX Bangladesh.

Gravel roads are the second cheapest among all the types of roads and they are also better than earthen roads. In this type of roads, the mixture of gravel and earth (available soil at the site) is paved on the surface and compacted. Gravel roads are also called as metal roads. These types of roads are easily built and generally laid in villages. They are common in less-developed nations, and also in the rural areas of developed and developing nations such as Bangladesh. SIMEX Bangladesh construct gravel roads across the rural Bangladesh over many years.
