Horizontal/Subsurface Infrastructure & Transportation

If that is asphalt pavement over a concrete base then it is likely that those are reflective cracks at the concrete joints.  Very common in this type of overlay with and without thermal factors.

​​That looks to be a subbase issue, not a surface failure. You can see how deep the cracks go.  Also, usually transverse cracking that is uniformly spaced is caused by a concrete road base joint. Do a core test to see what the base is.

Surface failure is typically seen as meandering cracks tightly spaced together, also known as alligator cracking (like the back of an alligator!). The larger the space between the cracks, the deeper the problem is.

Asphalt pavement overlaid on PCC base? The transverse cracks occur where there are joints in the concrete.

​Where is this located?  If a freeze environment, then yes, could be low temperature related thermal cracking.  Results from contraction of the asphalt concrete due to low temperature and friction of the base restricts movement resulting in regularly spaced transverse cracking.
