Hot Mix vs Cold Mix Asphalt - Advantages and Disadvantages

Nov 27, 2019  Strength – Hot mix asphalt is the most durable grade of paving asphalt, which is why it’s used for high traffic roads and highways. Cold mix asphalt isn’t strong enough for regular vehicle traffic. Bend but Not Break – Asphalt is more flexible than it’s paving counterpart concrete. Asphalt’s flexibility and malleability allow it to ...

Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.
