THE OVERLOAD IMPACT ON DESIGN LIFE OF FLEXIBLE PAVEMENT

Overloaded vehicles is one of the main problemsthat cause premature failure in road infrastructure. This paper presents an analysis overloaded vehicles'effect on flexible pavement based historical weigh-in-motion data. Thisarticle highlights potential use (WIM) data design by addressing overload, percentage overloading, and axle load distribution. The can reach more than 80% total number trucks maybe substantial factors that reduce pavement's service life. actual traffic presented form distribution for each type (axle spectra) Vehicle Damage Factor (VDF) truck type. effect overload life estimated using Cumulative ESAL comparison Pavement Ratio. Both analyses show significantly decrease up to nearly half
