Using asphalt for road surfaces has many advantages. It has minimized impact on the environment from its production to its placement on the road. Asphalt requires very low consumption of energy for production and construction. This means emission of greenhouse gases is reduced and natural resources are well conserved. Overall, asphalt is the most eco-friendly option for road construction.
Gathered here are some of the benefits of asphalt to the environment.
1.Its contribution to energy conservation and recycling
Compared to other types of road surface materials, asphalt uses around 20 percent less energy to produce. Another plus side of it is its recyclability. Old asphalt can be recycled so almost nothing is put to waste.
2.It doesn’t cause traffic for long periods.
When used as road surface, the roads can almost immediately be used causing no delays for public travel. Asphalt sets quickly and be passable in just a few hours. Moreover, asphalt gives the road a smooth surface, speeding up travel and reduces fuel consumption.
3.It strengthens roads and lengthens its lifespan.
If asphalt is properly applied, roads take a long time before wearing out. Its maintenance is very simple. The upper layer is just removed and replaced. This maintenance procedure can be done in a short period of time.
4.Its impermeability has so many uses and advantages.
By providing an impermeable surface, its petroleum content does not leach into the ground. It may be used for some other purposes like in drinking water reservoirs, fish ponds and even landfills. Its impermeable characteristic provides strong barrier to potential leaks.
5.It contributes to cleaner air and cooler surroundings.
Unlike the production of other road surface materials, asphalt produces very low emissions of greenhouse gases. Asphalt production is regarded as a minor source of industrial pollution. Additionally, asphalt helps to mitigate the urban heat island effect. Urban heat island effect is a condition where the urban areas get warmer due to land surface modification.
