Every country or city in the world lays special emphasis on their road and pavement construction and with good reason. Without a well-made and intelligently designed pavement the city could suffer in multiple ways. Numerous people, cycles, carts, vehicles travel via these pavements regularly. The function of pavement design are twofold, to provide enough friction so that vehicles may find it easy to travel via them and to transfer stress to the underlying soil. If built without proper planning the pavement is likely to crack under the tremendous pressure which will invariably create chaos among the public and also bring down the image of the cities. It is so important for the effective planning of a city that many organizations have sprung up that help in the construction of clever pavement design. One such Romanian company is Beton amprentat that specializes in construction of intelligently designed pavements.
Brisbane, an Australian city is known for laying special emphasis on their pavement planning and is in the process of constructing a runway as of 2019 that has been globally approved. The measurements for the new pavement are 3.3 km dedicated to runway and 12 km dedicated to taxiways. The runway pavement is built of almost 2.5 m of compacted sand covered with layers of fine-crushed rock and aircraft-grade asphalt. Asphalt is a kind of petroleum that is used to construct runways frequently since it is a material that is known to withstand the weight and pressure of landing aircrafts and yet it is flexible and easy to maintain. Since runways often need correction, the usage of asphalt makes it all the more convenient since the material’s flexibility leaves room for future shape corrections.
The taxiway too, much like the runway, is built of 1.5 m of compacted sand covered with finely crushed rock and concrete. The taxiway uses concrete instead of asphalt as it can withhold the tremendous pressure of a few aircrafts awaiting for clearance to take-off.
The runway which will finish construction and become operational around mid 2020 is known to have utilized near and about 100,000 tonnes of asphalt and 380,000 tonnes of concrete.
