If this phenomenon takes place due to temperature conditions, the crackings spreading effect occurs in the opposite way, thus micro-crackings are provoked from the grade line and they are spread towards the inner fiber in the asphaltic layer.
Si este fenómeno ocurre por temperatura el efecto de propagación de fisuras ocurre de manera contraria, las microfisuras se generan desde la rasante y se extiende hacia la fibra inferior de la capa asfáltica.
