EVALUATION OF THE CEMENT CONCRETE AIRFIELD PAVEMENT'S TECHNICAL CONDITION BASED ON THE APCI INDEX

One of the factors that affects the safety of flight operations is to maintain the airport infrastructure in an appropriate condition, due to importance of proper infrastructure management, including funds and human resources management in particular. Currently applicable methods for determination of surface condition arc mainly based on visual assessment of surface deterioration. An innovative approach to assessing the cement concrete airport pavement's technical condition based on the APCI (Airfield Pavement Condition Index) is presented in the article. The method of APCI index determination is based not only on the visual assessment of the airfield pavement's surface condition and the calculation of its deterioration. but also includes parameter of load capacity, evenness, mughness and tensile strength of the surface layer. The presented method can he used as a tool for forecasting the technical condition of cement concrete airfield pavements in the context of planning funds for future maintenance purposes. The impact of considering individual model parameters on the value of APCI index, basing on the results of field tests carried out as part of military airports inspections was presented.
