This article investigates the formation of elevations between cement-concrete pavement slabs on the 228-581 km section of the A-380 "Guzar-Bukhara-Nukus-Beyneu" highway and the reasons for their impact on road surface smoothness. Experimental studies were conducted using the "TRASSA" mobile road laboratory. Based on the obtained results, the elevations in the expansion joints between concrete pavement slabs and their negative impact on road surface smoothness were evaluated. The study also considered the operating conditions of cement-concrete pavements and the influence of moving loads on the expansion joints between the slabs. The article analyzes how these elevations between slabs negatively affect road safety and the long-term performance of the road for vehicular traffic. The obtained results serve to identify problems that arise in the production and operation of cement-concrete pavements and to develop practical recommendations for their elimination. The study also demonstrates the necessity of applying advanced technologies in road construction to enhance the quality of roads and improve their effective management.
