The assessment correctness of runway pavement surfaces is a crucial element ensuring safety during flight operations. Foreign and national normative documents specify the required values of coefficients of friction both for designed (new) and utilized runway pavement surfaces and/or those subject to planned renovation works. What is more, the above mentioned documents determine the minimum (limit) values for operated runway pavement surfaces. Furthermore, they also describe the general requirements as regards measuring devices applied to specify the roughness of runway pavement surfaces. The accepted repeatability (Equipment Variation) of coefficient of friction measurement is not sufficient to approve the device for roughness measurements of aerodrome functional elements. Due to this fact the device is authorized to take measurements of coefficient of friction under the condition that it is preceded by certain studies carried out in order to establish its usefulness. These research consist inter alia of the device evaluation in view of devices authorized to perform measurements, using statistical apparatus. Final evaluation of instrument usefulness includes additionally the whole gamut of technical problems associated with the operation process, its preparation, calibration (checking) before taking measurements and the measurements themselves.
The paper follows the potential practice of fiber reinforced concrete (FRC) as a solution for airport`s runway pavements, in order to increase the bearing strength, resulting in decreasing the height of the concrete layer that is currently used.
Experimentally, the study focuses on the properties of fiber reinforced Portland cement concrete using 3 different percentages (0.5%, 1% and 1.5% of the concrete volume) and 4 different types of fiber (for 1% percentage – hooked steel fiber 50 mm length, hooked steel fiber 30 mm length, crimped steel fiber 30 mm length and polypropylene fiber 50 mm lenght), using as reference a plain concrete with 5 MPa flexural strength.
More exactly, the study presents the change in compressive and flexural strength, shrinkage, thermal expansion factor, elastic modulus and Poisson`s ratio over fiber type and dosage.
For the highest performance concrete (7 MPa flexural strength), it has been made a study using two methods for rigid airport pavements design (general method and optimized method), and one method for evaluation of bearing strength (ACN – PCN method), which is compared to a plain 5 MPa concrete. Furthermore, the decrease in the slab`s thickness proportionally to the growth of the flexural strength is emphasized by evaluating the slab`s height for a high performance 9 MPa concrete using both design methods.

The load-carrying capacity, is one of the indicators used to assess airfield pavement conditions. It could be estimated by evaluating the response of stationary dynamic loads, using a deflectometric device that simulates the stress inducted by an aircraft moving at moderate speed. This device is widely used because tests are nondestructive and rapid to execute and can be conducted for cyclic investigations, providing valuable support to maintenance and rehabilitation (M&R) decision makers through pavement management system (PMS). Pavement response is evaluated as a function of the deflection basin induced by the deflectometric device. It is well known that deflectometric measurements are influenced by external parameters such as weather conditions, especially temperature of upper layers or the percentage of water contained on unbounded layers. In this study the deflections basin response obtained for different load and weather conditions has been analyzed through the application of benchmarking values for immediately structural assessments. Tests were performed using the Heavy Weight Deflectometer (HWD) on 9 points along five longitudinal alignments from the centerline, 0.00 m, ± 3.00 m, and ± 5.20 m. The benchmarking methodology was used to evaluate and compare runway pavement performance under different weather conditions and testing loads. The applied benchmarking methodology resulted an easy and rapid assessment tool of pavement conditions at network-level.
This manuscript presents a research method that will be used in the development process of avionics equipment. A special device predicting braking and take-off distances will help pilots and provide a complex increase of flight safety and decrease of some types of charges.
