الملخص

The main objective of this work is to study of effect of rainfall intensity on the thickness of pavements layers of flexible pavement structure. This is using Maple 13 software for modeling of this problem and calculation the rainfall intensity and pavement infiltration. It was found that pavement infiltration increases with increasing rainfall intensity because of, the increase in the rainfall intensity caused an increase in the infiltrated water to the base and sub - base layers. Accordingly an increase in pore water pressure resulted which intends cause an increase in porosity and decrease of base and sub - base degree of compaction. Accordingly which leads to increase in time - to- drain, decrease in drainage coefficient for base and sub - base, and subsequently, request to increase their thickness. For flexible pavement, rainfall intensity 256 mm/hr is giving pavement infiltration.
