How does cold weather affect asphalt and concrete ...

In extreme low temperatures, the asphalt or concrete surface contracts and shrinks and this causes tension in the surface. If this tension becomes very strong, cracks appear in the paving surface to release the tension generated. When there is a rapid decrease in the temperature the contraction happens at a faster pace and tension builds in faster. This creates a conducive environment for ...

The reality of cold weather compaction Asphalt magazine

It is helpful to understand some basic parameters that affect every asphalt pavement’s compactability. Compactability is seen as the relative resistance a mix offers to compaction efforts. Generally, asphalt mixtures are designed to be compactable during typical weather conditions during the construction season in a given area. However, when paving is done early or late in the construction ...
