The work is devoted to improving the principles of streets and urban roads beautification elements placing. The classification of streets and urban roads beautification elements is structured. The principles of streets and urban roads beautification elements placing by using new spatial corridor principle simulation are improved. Streets and urban roads beautification elements according to hierarchical levels are structured. The street structural model spatial corridor with distribution in sub corridors to deploy beautification elements is constructed. The spatial corridor and subcorridors characterized by linear parameters and formulas for their determination are suggested. The methodology of comprehensive streets and urban roads beautification designing according to the offered principle is improved. Reconstruction beautification experimental design of Shevchenko Street in Poltava, Ukraine is done.

The technique and its numerical realization of the hard airdrome coatings specified calculations with the consideration oftheir interaction with heterogeneous multilayer weak soil half-space is proposed. Numerical simulation of the hard airdromecoatings stress-strain state is carried out on the basis of the relations of the elasticity nonlinear theory with the help of thefinite element method momentary scheme. The task of calculating the actual concrete coating on a rigid artificial basis of theInternational Airport "Odesa" runway is solved. A finite-element model for calculating hard surfaces with the use of amomentary finite element scheme and a universal spatial shell finite element has been developed.

The state and provision level of road traffic participants to the objects of service on Egypt highways have been analysed. Ingeneral, there are a number of significant shortcomings regarding the systematic approach in justifying and standardizing thedistances of the road services location, considering the requirements of road users. With the help of Google Earth and realsurvey, the current status of the service objects along the Egypt highways and in foreign countries of the world has been surveyed.The obtained data show that service facilities are unevenly located in Egypt, often do not meet normative requirementsand are not characterized by complexity. Instead, in foreign countries there is even more distribution of complex servicefacilities along highways, all service facilities has transition-high-speed bands and the vast majority have separate congresses.
