Adel A. Regularity development of destructions of the road flexible pavements as a basis for planning of repair works (on an example highways of Yemen)

The object is destructions development processes of the road flexible pavements. The aim of research - improvement planning of highways repairs on the basis of destructions modeling processes of the road flexible pavements in conditions of a hot climate. Methods of research - the pavement strength of a road flexible type was defined on an elastic deflection, which was measured on a road with the help of a Benkelman beam (deflectometer of a lever type), and on the modified structural number SNC. Pavement evenness measured on a technique of the International Roughness Index IRI. The types of destructions and their area were defined by results of measurements on a road. For the analysis of research results and development of destructions model the method of mathematical modeling is used. Scientific novelty - regularity's establishment of destructions development of the road flexible pavements under complex influence of loadings from vehicles and factors of external environment. Extent of introduction - results of research, which are given in dissertation work are used in course designing and research works of the students on faculty of construction and operation of highways of Kharkov National Automobile and Highway University. Field of introduction - in the road enterprises of Yemen and Ukraine; in an educational course "Operation of highways" by preparation of the experts on a specialty 7.092105 "Automobile roads and aerodromes"
