Abstract

The Nekemte-Bedele road section is experiencing various flexible pavement failures, and a study is needed to determine the causes. The study will involve desk research, field inspections, and laboratory tests to identify the reasons for the failures in sub-base and subgrade materials. During field observations, different types of pavement failures were noted, such as rutting, potholes, edge cracking, transversal cracking, and raveling. Representative samples were taken from the deteriorated sections to perform laboratory tests like Atterberg limit, gradation or sieve analysis, compaction, and CBR. The laboratory results showed that most of the soil materials used along the road did not meet standard specifications. The plasticity indexes and liquid limits were high for all sub-base, selected fill, and natural subgrade soil samples, except for a few. The OMC was almost between 11.90 - 27.80%, and the MDD values ranged from 1.30 kg/m³ - 1.92 kg/m³. Most of the CBR values for the selected fill soil materials met specification requirements, while those of sub-base and natural subgrade soil materials did not meet the specifications, except for a few samples. The pavement failure was due to weak/poor soil pavement layer performance in different failed locations. The field recorded high, medium, and low levels of severity.
