Advantages of Concrete Roadways
There are several advantages to using Concrete for road ways as opposed to Asphalt. Below we explore some of those positives.
- Durability and maintenance free life: Concrete roads have a long service life of forty years, whereas asphalt roads last for ten years. More over, during this service life concrete road do not require frequent repair or patching work like asphalt roads.
- Vehicles consume less fuel: A vehicle, when run over a concrete road, consumes 15-20% less fuel than that on asphalt roads. This is because of the fact that a concrete road does not get deflected under the wheels of loaded trucks.
- Resistant to automobile fuel spillage and extreme weather: Unlike asphalt roads, concrete roads do not get damaged by the leaking oils from the vehicles or by the extreme weather conditions like excess rain or extreme heat.
- Greener process: Asphalt (bitumen) produces lots of highly polluting gases at the time of melting it for paving. Also, less fuel consumption by the vehicle running on a concrete road means less pollution.
- Saving of natural resources: Asphalt (bitumen) is produced from imported petroleum, the reserve of which is becoming reduced drastically. On the other hand, concrete (cement) is produced from abundantly available limestone.
