摘要

The attention to rapid pavement repair has grown fast in recent decades: this topic is\udstrategic for the airport management process for civil purposes and peacekeeping missions. This work\udpresents the results of laboratory and on-site tests for rapid runway repair, in order to analyse\udand compare technical and mechanical performances of 12 different materials currently used in\udairport. The study focuses on site repairs, a technique adopted most frequently than repairs with\udmodular elements. After describing mechanical and physical properties of the examined materials\ud(2 bituminous emulsions, 5 cement mortars, 4 cold bituminous mixtures and 1 expanding resin),\udthe study presents the results of carried out mechanical tests. The results demonstrate that the best\udperforming material is a one-component fast setting and hardening cement mortar with graded\udaggregates. This material allows the runway reopening 6 h after the work. A cold bituminous mixture\ud(bicomponent premixed cold asphalt with water as catalyst) and the ordinary cement concrete allow\udthe reopening to traffic after 18 h, but both ensure a lower service life (1000 coverages) than the cement\udmortar (10,000 coverages). The obtained results include important information both laboratory level\udand field, and they could be used by airport management bodies and road agencies when scheduling\udand evaluating pavement repairs.
