For drivers who often drive on the highway, asphalt pavement is all too familiar. However, whenever you pass by the toll booth, the characteristic cement pavement is always a curiosity. Why does the road surface suddenly turn cement at the toll booth on the expressway? In fact, there are multiple considerations and reasons behind this.
First of all, we need to understand that the toll booth of the highway is where the vehicle has to slow down or stop. Such characteristics make the road surface need to withstand the force of the vehicle's sudden braking. In contrast, although the asphalt pavement is flexible, it has a weak bearing capacity for sudden braking, which is easy to cause damage to the road surface. The cement pavement is hard and wear-resistant, which can better withstand the force of this sudden braking and ensure the durability of the road.
Secondly, the temperature has a great influence on the asphalt pavement. In hot weather, asphalt pavement is prone to softening, which can not only emit an unpleasant odor, but also may have an impact on the health of the driver. In contrast, cement pavement is more adaptable to temperature and can maintain good performance in both high and low temperature environments.
In addition, from the perspective of service life, the advantages of cement pavement are also very obvious. Asphalt pavements have a relatively short lifespan and require frequent maintenance and replacement. Concrete pavement, on the other hand, has a longer service life, reducing the cost and time of road maintenance.
In addition, the water-quality of the cement pavement is also better. In case of rain or standing water, asphalt pavement is prone to slippage, while concrete pavement provides better grip and ensures driving safety. Especially at toll booths in low-lying areas, this feature of cement pavement is particularly important.
Finally, the cement pavement is also noisy. In the toll booth area of the expressway, there may be congestion of vehicles. At this time, the louder noise can alert the driver to the vehicle in front of him, improve his attention while driving, and further ensure driving safety.
The above is the reason why the toll booth uses cement pavement. What are your thoughts on this? Or do you think there are other reasons? Feel free to leave a comment below, and we'll see you next time.
