  3. Economically Justified Levels of Road Works Expenditures on Unpaved Roads • Unpaved roads require periodic road works to maintain a certain road condition over time that require planning and economic justification. • A main concern is defining a proper level of investments and quality of maintenance on these roads. • This note presents a methodology for an analytical study done to access economically justified levels of road works expenditures on unpaved roads with different traffic levels. • The results should be considered no more than a first approximation of country specific results.
