Concrete or Asphalt?

The compressibility of rubber, EVA and a sock have considerably more contribution to the impact transmitted to the foot within the shoe than the difference between concrete and asphalt. Consider that the difference in hardness between concrete and asphalt is equivalent to adding less than 1mm of extra rubber to the sole of a shoe.

Crumb Rubber Modifier in Road Asphalt Pavements: State of

When crumb rubber is used as a portion of aggregates in hot mix asphalt concrete, the resultant product is sometimes referred to as rubber-modified asphalt concrete (RUMAC). This type of mixture usually contains 1 to 3 percent of rubber by weight of the total aggregate in the mix and target air void content from 2 to 4 percent [ 17 ].

Pavement Manual: Compaction

Lateral distortion - shoving of the pavement material sideways and a humping-up of the asphalt concrete mixture outside the wheelpaths - is usually due to a mix design problem. Both types of rutting can occur more quickly if the HMA air void content is too low (Scherocman, 1984a).
