Need to feet with the growth of traffic volume and have to be Cost effective.ДЇor such reason, most of the road lines need maintenance every moment which is not cost effective. While constructing these roads the quality and capacity of the roads Also the rate of growth increase 3% every year.Д«ecause of these situations, the city administration construct and maintain the roads more highly than ever. From this amount 61.73 %( 362,664) are found in Addis Ababa. According to transport ministry there have 587,453 total number of vehicles which are registered up to June 2015 in Ethiopia.

This number has been increased from the originally published 2,738,248 figure and appears to be still largely underestimated.ДЄddis Ababa which have a large amount of growth in traffic activity. This research was conducted in Addis Ababa the capital city of Ethiopia which had founded in 1886, it is the largest city in Ethiopia, with a population of 3,384,569 according to the 2014 population census with annual growth rate of 3.8%.

To provide practical suggestions and recommendations aiming to upgrade the knowledge of applying geosynthetic material on construction of road projects. To determine the major cost effectives of geosynthetic materials. To determine the major effectives of geosynthetic material on paved on road performance based on laboratory test. It seems reasonable to assume that the first attempts were made to stabilize swamps and marshy soils using tree trunks, small bushes and the like. Bipin J Agrawal) The addition of materials possessing properties that would enhance the behavior of the soil itself was no doubt done long before our first historical records. Since Geosynthetic materials, a newly emerging field in the civil engineering and other fields, it offers great potential in varied areas of applications globally.

Geomembrane, in this study reviewed, tended to performД«etter for bases, especially where subgrade strengths were below a CBR of 3 (MR of 30 MPa).Д«y reducing the undercut and thickness of base and subbase material, geomembranes can save initial construction cost of road also the life cycle cost by increasing the design life of the road.

In evaluating the effectiveness of geosynthetic from this study on permanent paved roads, it is easy to develop that geosynthetic materials can improve the performance of road. This was accomplished by the testing of a total of 8 pavement core samples and 11 CBR test sections which could be classified into two different types: one which was constructed without geosynthetics and one with one of two geomembranes or a geogrid. This shows the traffic volume in the city is increasing through the years, so that increasing roads performance should be considered.Д®xperimental and analytical investigations were performed to evaluate the comparative performance of pavements with and without geosynthetic stabilization. These number of vehicles increase 2% every year. From these amount 362,664 vehicles are found in Addis Ababa. According to transport ministry data there have 587,457 vehicles in Ethiopia registered up to July 2015. Since Addis Ababa is the Capital city of the country, the increase of traffic volume is the other challenge for the roads. In large cities, the problem become one of the challenge for the economic activity of the country. Hence there have multi problems which are caused by poor quality subgrade or material used for construction. The traffic volume and traffic loads on these roads are getting higher. Road projects, involving large amount capital, also contribute to the total economy through job creation and in a ripple effect to other business activities. Development strategies which are fulfilled through successful road projects out end to import accessibility of urban areas, lower costs associated with transport maintenance and open more areas for development activities. Road sector construction projects in Ethiopia are means through which development strategies are achieved. Key words: Geosynthetic material, Geomembrane, CBR test, Asphalt core sample test, and result and discussion. It has been done on road construction projects under Addis Ababa Road Authority.
