The reality of cold weather compaction Asphalt magazine

As mix delivery temperature is typically under the contractor’s control, this is the logical first step during cold weather paving. During production, asphalt mixture should be produced at the higher end of the appropriate range for the project’s asphalt binder. Use of insulated truck beds that are tarped to minimize temperature loss is encouraged.

Talking Asphalt: Winter Paving – October 2012 Asphalt ...

Another approach to achieving better compaction in cold weather is to use warm mix asphalt (WMA). One of the reported benefits of WMA is that it extends the paving season. WMA does not cool as quickly as HMA and it is still workable/compactable at lower temperatures. Some contractors routinely use a WMA technology as a compaction aid for normal work. Numerous WMA projects have been placed

Cold Weather and Concrete Pavements

Paving in cold weather often requires the use of insulating blankets to keep the concrete temperature high enough to allow the hydration reaction to occur and prevent the water in the concrete from freezing. The maturity method is an excellent technique to monitor not only the strength gain of the concrete, but also the internal temperature of the slab during cold weather placement. Snow and ...
