I, a newcomer to this field, would like to ask the more experienced members: is it more fuel-efficient to use asphalt roads or concrete roads? Why?

I checked some websites, but the information there contradicted each other, so I’m not sure which option is more fuel-efficient. Many say that concrete roads are more fuel-efficient due to lower friction. . I feel like the driving force is just the friction force, reversed in direction and of equal magnitude, right? Shouldn’t it be the case that higher friction results in better fuel efficiency? Seeking advice, thank you all
Cement roads use less fuel because of the higher friction
What are you asking about – fuel efficiency, cars?
Asphalt roads offer good comfort and cause less wear on tires; I don’t like concrete roads.
I like asphalt roads too:victory: Whether it saves money or not, as long as roads can be built, that’s better than having no roads at all:victory:
Hmm, for driving, is it more fuel-efficient to use concrete roads or asphalt roads? Thanks
I think concrete roads save fuel, while asphalt roads are more comfortable to drive on. Each has its advantages
Actually, I think not driving a car is the most fuel-efficient way
The magnitude of friction is first determined by the coefficient of friction: the coefficient of friction for cement pavements is 0.22–0.4, while that for asphalt pavements is 0.6. It can be seen that the resistance associated with f-μN is greater for asphalt roads than for cement roads. During the restart of the vehicle, when the pulling force F is less than or equal to the friction force, the vehicle remains stationary; when F is greater than the friction force, the vehicle starts moving. Therefore, the minimum force required for the vehicle to start moving must be greater than the friction force. Therefore, W=FS; the greater the force, the higher the fuel consumption
