Asphalt pavement failures at four levels of highways, main streets, local streets, and alleys were assessed through related forms and MicroPAVER software. Distress of crocodile cracks and weathering are the most quantity of failure expressing the lack or poor quality of materials and amount of bitumen.

According to these values and PCI requirements, strategies were proposed to improve pavement conditions at each level and specific PCI values.
