The paper justifies improvement of a local road through an integrated water-subgrade-base-pavement system. The submitted graduation-project materials report, for the km 0-3 section of road 4K96, a 2025 mean elastic modulus of 142 MPa, a skid-resistance coefficient of 0.32-0.38, longitudinal cracking of 104 m/km, and alligator cracking of 137 m²/km. These values were not independently remeasured for this paper, and that limitation is stated explicitly. The engineering strategy prioritises drainage restoration, local treatment of weak subgrade, calculated use of geosynthetics only where supported by testing, base reprofiling, shoulder strengthening, and controlled pavement renewal. An illustrative runoff calculation shows how drainage capacity should be checked against the contributing catchment. The proposed sequence is intended to extend service life and reduce repeated rehabilitation expenditure while retaining pavement materials that remain serviceable.
