Selected Aspects of Evaluating the Technical Condition of Concrete Airport Pavements in Terms of Service Life

Abstract

The paper presents the essence of airport pavements' durability in terms of its condition's evaluation. It features a discussion of selected research methods for the most important pavement parameters. It was proposed to expand the existing pavement condition evaluation process with selected verification methods. The use of geo-radar measurements in connection with the specification of the pavement concrete's durability and concrete pavement's internal structure analysis seems to be a necessary element supplementing the currently used evaluation procedure.

Reinforcement Corrosion Testing in Concrete and Fiber Reinforced Concrete Specimens Exposed to Aggressive External Factors

“…Fiber-reinforced concrete is a “quasi-plastic” and “quasi-homogeneous” material, having better adhesion, deformability, tightness and higher early strength [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. This is important in the case of structures exposed to aggressive environments (i.e., bridges, tunnels, viaducts, car parks), thin-walled elements (tanks and basins of swimming pools), weirs, retaining walls, elements subjected to dynamic loads and concrete surfaces, including airfield pavements [ 29 , 30 ] and industrial floors. Randomly dispersed fibers in the concrete mix reduce stress concentration and thus limit cracking [ 20 , 21 , 22 , 28 , 31 ].…”
