Abstract: In most developing countries, particularly Niger, unpaved roads account for more than 70% of the national road network. Their widespread use is justified by the availability of construction and maintenance materials in the immediate vicinity of project sites. However, these roads have limited durability because of the characteristics of the borrow...

Abstract: E-waste i.e., electrical & electronic waste is growing very fast these days with increase in electrical and electronic industries worldwide. The disposal of e-waste has been a global threat to the environment for many years. The recycling of e-waste materials in making concrete is not only being considered as most feasible solution to this global problem of disposal of e-waste to a great extent but it saves our natural resources of aggregate also. The work was conducted..
