Flexible pavement is usually designed based on certain axle load limits and climatic conditions. The Iraqi code has specified per each type that should not be exceeded. However, many trucks violate these by carrying additional weights to decrease the transportation cost. These overweight cause severe deterioration thus reduce its life. authorities generally charges violating a penalty their wei...

The purpose of this research was to study the feasibility incorporating steel slags into coarse bituminous mixtures. objective twofold: reduce dependence on natural aggregates, and provide a use for industrial by-products. studied come from manufacture carbon in electric furnaces are divided two types: Electric Arc Furnace (EAF) slag Ladle (LF) slag. mixture designed is concrete (AC22G), base c...

In this study, Gene Expression Programming (GEP) is used in modeling the deflection basins measured on the surface of the flexible pavements. Backcalculation of the pavement layer moduli are well-accepted procedures for the evaluation of the structural capacity of pavements. The ultimate aim of the backcalculation process from Nondestructive Testing (NDT) results is to estimate the pavement mat...

in this study, an artificial neural network was developed in order to analyze flexible pavement structure anddetermine its critical responses under the influence of standard axle loading. in doing so, more than 10000four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, andsubgrade soil were analyzed under the impact of standard axle loading. pave...

The National Airport Pavement Test Facility (NAPTF) is a state-of-the-art full-scale test facility operated by the U.S. Federal Aviation Administration (FAA). The NAPTF is located at the William J. Hughes Technical Center near Atlantic City, New Jersey and it provides high quality, accelerated test data from rigid and flexible pavements subjected to simulated aircraft traffic. During the first ...
