Nine types of nanomodifiers designated for asphalt binder are considered in the article. Three mineral material types of are considered, including dolomite powder MP-1, diatomite and activated silica sand. As the second component cotton oil, synthetic rubber and a colloid solution of ferric (III) hydroxide and silica acid are selected. The results of the study disclose the influence of nanomodifiers on needle penetration depth at 0 °C and 25 °C, as well as the softening temperature, brittleness properties and stability after aging. The penetration depth is a criterion of the ability of the bitumen to resist mechanical stress, while brittleness and / or softening are the criteria of its ability to resist temperature. The generalized effectiveness criterion of bitumen modifiers is also taken into account. The generalized effectiveness criterion of nanomodifiers was revealed based on the obtained data. One of the most effective modifiers is diatomite with a colloid solution of ferric hydroxide (III) and silica acid. Dolomite powder with sol and diatomite with synthetic rubber (layer 70 nm) are promising methods of modification, though they require optimization in terms of their technology and formulations.

The principal objective of the research project is to identify the thickness of an advanced
composite adhesive material used as part of a glued connection of wooden surfaces. The active
ingredients of the proposed adhesive material include an epoxy matrix and a glass fiber fabric. The
author has analyzed the bearing capacity and deformability of the proposed connection in relation
to the thickness of the composite material. The author used the methodology of assessment of the
bearing capacity of wooden structures developed by professor Yu.M. Ivanov. For the purposes of
development of optimal parameters of the "QM Glued" connection, the author identified the optimal
ratio of b, or width of the surface of connected elements, and the thickness of the composite material:
t = 1/40 b.
