Hot Mix vs Cold Mix Asphalt - Advantages and Disadvantages

Nov 27, 2019  Cold mix asphalt is most useful for repairs like small cracks and potholes or patches when the outside temperature is too cold for hot mix asphalt. Cold mix asphalt is not nearly as strong as hot mix asphalt and should only be used for small-scale fixes or temporary patches until a more permanent repair with hot asphalt mix can be made.
