Regional field notes
Semi-arid, high-plains climate
The Mountain West and high plains combine two tough conditions: strong high-altitude sun and dry air that oxidize asphalt, plus cold winters with real freeze-thaw cycling. Wide temperature swings between seasons — and between day and night — mean pavement here faces both UV aging and cracking from thermal movement, so it needs protection on both fronts.
Thinner air and abundant sun age asphalt quickly, drying out the binder and leaving surfaces brittle and prone to raveling.
Cold winters and snowmelt still drive freeze-thaw damage, so any unsealed crack becomes an entry point for water that widens it each cold snap.
Big day-to-night and seasonal temperature ranges expand and contract pavement constantly, fatiguing the surface and encouraging thermal cracking.
