As trees grow, the roots will always seek to stretch out in every direction and they won’t discriminate between asphalt or concrete when it comes to causing damage to anything they travel under.
The photo below shows a concrete hardstand floor that has been damaged by root growth of a nearby gum tree. The photo does not show the rise of the concrete, which is about 20 cm and has rendered the floor unusable. In this case there is no other option but to remove all the concrete and start over, also requiring replacement of the shed it supports. Had the floor been asphalt, the damage would have been much less, even if left un-maintained for the same amount of time. Asphalt is move giving than concrete, particularly when vegetation is nearby. In this case the owners have opted to remove the concrete and relay the surface with asphalt. While the gum tree has been trimmed, it will live on for many more years and allowed room to prosper. Any movement in the asphalt will result in a minor repair instead of a complete resurface. Morale? Always choose asphalt over concrete to allow the garden to grow.
