| dc.description.abstract | Now a day than it was before road pavement damage associated with vehicle overloading particularly from those heavy vehicles are becoming increasingly threatening in Ethiopia. Most of the road pavements constructed since the last 10-15 years are deteriorating much before their useful design life (period) and are calling for early overlay if not for complete reconstruction. This is mainly associated with the growing economy of the nation and associated increase in transport demand. The ever growing demand in transport in turn calls for an effective transport system. One way of achieving this is currently manifested by introduction of heavy trucks and truck trailers for transporting goods. Although this is a normal trend in growing economies the damage that these vehicles induce on flexible bituminous surfaced roads is intensified by excessive overloading exceeding the permitted axle load limits. With this in mind and to study the effect of overloading and the role of axle load regulations the research therefore focused on the following two objectives: • How does vehicles overloading affect the pavement service life • Role of axle load enforcement or regulation Accordingly the road segment from Adama to Awash is selected for this study. The Adama - Awash road as part of the main import-export Highway is carrying a considerable amount of truck and truck trailers travelling to and from the port of Djibouti. Furthermore it also serves traffic that are coming and going to the eastern part of the country mainly joining the port traffic at Awash. Despite a pavement with thick asphaltic layer currently the asphalt concrete is intensively and extensively cracked. It is heavily deformed with extreme undulation and deep rutting to the extent of causing traffic hazard at a number of places particularly along climbing lanes. This is even worst starting from the town of Wolenchiti to that of Metehara and near the Awash bridge crossing where the route corridor is characterized by several ups and downs with high day time temperature (hotter climate). Therefore it is considered to set a very good example for the adverse effect of overloading in line with the core objective of this research. | en_US |
