Rubber has greater compression than asphalt or concrete, which can be a benefit to a vehicle that hits it too quickly, at an angle, or is low to the ground, because it is less likely to do the vehicle damage. This greater compression means that rubber obstacles of the same height are slightly less effective at slowing traffic than similar asphalt installations, and rubber or plastic are not ideal for roads on which there is constant passage of heavy industrial traffic. However, in normal conditions, rubber is tough and long lasting, and is inexpensive to buy and install.
