Abstract—In most of the underdeveloped and developing countries, every year considerable kilometers of new roads are constructed along with the periodical maintenance and rehabilitation of the existing road network. All these construction and maintenance programs require a great deal of construction materials. Again in many countries, limited sources of good quality materials also hinder road construction. Every year, millions of tons of mineral aggregates are imported from abroad for the purpose of special and large scale highway construction and maintenance. For general purpose road construction and maintenance work, locally occurring rocks, gravels and sands are used, but the good quality resources are decreasing but aggregate demand is increasing. Recycling of pavement has not yet been popular in most of the underdeveloped and developing countries and so they depend mostly on imported materials for road construction and maintenance though use of recycled materials have been performed in pavement constructions for many decades in the developed counties. This paper presents a brief overview of in-place recycling-repaving process of aggregates used in road reconstruction and maintenance in Bangladesh which can be an easy solution of ongoing and future material demand.
