چکیده مقاله:
It is very important to determine the layer/ layers because the rutting distressin the highways pavement those suffer from rutting distress, so an accuraterehabilitation strategy is selected. In this study, the Ground PenetratingRadar (GPR) used in detection of rutting distress that Al-Kut Baghdad ruralhighway suffers from, using 800 MHz antenna. The selected highwaysuffers from excessive rutting (2-4 cm). According to the processed GPRdata, it is discovered that the sub-base layer causes the rutting in thepavement. The GPR results led to a need of conduction of a structuralevaluation to the sub-base layer by conducting CBR test, the CBR result ofthe sub-base layers is (18.7 Mpa) while the Iraqi specification for roads andbridges (SCRB, 2003) state that minimum CBR value for the sub-base typeB is (35 Mpa), this result confirmed the GPR results.
