Jul 02, 2006 · When I used to manage an asphalt plant, the temp. that you send it out all depends on several things. In the mix design, it will tell you the optimum temp for mixing and for compaction once it gets out to the road. I know from experience that once the mat reaches its designed low, well that is about all the compaction you are going to get.

Hot Mix vs Cold Mix Asphalt - Advantages and Disadvantages

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.
