It's a topic we don't think about very often, but it affects our daily lives. We go on sidewalks and drive on asphalt. But have you ever wondered what their real differences are? Here you will find an explanation of the contrasts between pavement and asphalt as well as some predictions for the future.
The basics of pavement and asphalt
Pavement and asphalt are produced for different purposes. The sidewalk is made for walking, so it has a high grip that allows people to walk without sliding. Asphalt is produced taking into account vehicle traffic, so it is relatively smooth and can carry heavy weights for years. It is important to remember that concrete paving can be used as a road surface and asphalt as a road surface. This has certain disadvantages.
Asphalt reflects heat, which can make it unsuitable for use as a paving material. This can lead to heat exhaustion in people who walk on asphalt for about an hour in hot weather. Symptoms can include headache and fatigue. Water is a simple solution, but an even better one would be a more suitable surface.
In which category is concrete?
Concrete, which is often used as paving material, is rarely used as road material for the following reasons. If the concrete is laid without steel reinforcement mesh, it tends to crack and then turns into rubble. Concrete is a great material, but not really for streets. The Romans could make concrete, but always used stones for their streets and sidewalks.
Asphalt can be called bitumen and was once known as asphalt. Hydrogen and carbon are the main compounds in it and when it is laid it is very sticky and stinks. The advantages are that it is smooth and can be laid quickly. Oil is also a key component. A major disadvantage is that if a crack occurs, rainwater can wash off the bottom of the road and thus wash the road completely. To counteract this, a new innovation was to put rubber tires under the asphalt to ensure stability. This should make the road last much longer than it currently does.
plasters have different surfaces. This can be concrete, brick, stone slabs and asphalt. Nobody really thought much about developing a better surface for many years, and it just seems to be accepted that this is the technology we are sticking to. Very often sidewalks tear due to the proximity of trees that push their roots through the surface, which means that the pavement needs to be re-laid.
It may seem more stylish to place brick or stone slabs as plaster, but these surfaces become slippery when wet. Local authorities can be sued for accidental injuries due to an improperly prepared surface. Therefore, concrete paving seems to be the best option as it provides sufficient traction in all weather conditions, even if they are not attractive to look at.
May be time for someone to reinvent the road surface to create a cleaner future. Innovations in road surfaces are also rare and are waiting to be improved as well. But you can rest assured that we will all be riding or running for many years to come.
