Thank you for your question. Sorry it has taken us so long to respond, we just saw the post. While there is no firm definition for "hot", the common temperature is 175F or higher. There are so many variables to consider. If you make a series of short pulls, tacking is still key along that joint to aid in compaction. Likewise, for the first pull, you may want to experiment with not compacting longitudinal joint until the second pull is completed so that the uncompacted lift heights are equal - essentially simulating echelon paving. Once completed, check with a gauge or cores to see what density was obtained. If you do it, we are interested to hear your results.

Love these videos! Question; at what temp is that joint no longer considered “hot”, inwhich you’d compact the unsupported joint prior to paying the adjacent lane, instead of compacting the hot joint first thing. I guess what I’m sort of asking is, can a hot joint only be attained through echelon paving? Or perhaps in the circumstance of short 40-50ft passes where there’s a joint, would you achieve optimal compaction through compacting that joint at once, as if it were a hot joint, or rolling the the unsupported joint first after the initial pass before laying the adjacent pass.
