It article contains information about mathematical models which taking into account more factors affecting on the performance of logging trucks. Presenting the methodical approach that allows engineers to make management decisions that control of forest real-time and determination: the optimal composition of logging trucks, their technical and economic indices, charts of wood hauling, the volume of construction, reconstruction and maintenance of logging roads, the costs for these purposes and etc.

Keywords: Automobile forest transport, logging truck, haul road, scheduling, performance of the logging truck.

Statement of the problem. Preparation of high-strength foam concrete in construction allows for energy and resource conservation. Water covers more than 50% of their dense component and on its properties depend strongly on structural properties of foam concrete, is not fully explored.
Results. The effect of mixing water of low temperature on the structure and properties of constructive penofibrobetonov. Recommendations on the account in the calculation of reinforced concrete elements elevated structural properties and deformation diagrams penofibrobetonov by mixing water setback.
Conclusions. Using low temperature mixing water improves the structure, increases the strength, deformability and elastic modulus, as well as changes of the deformation diagram fibropenobetonov.
Keywords: fibropenobetona, foam, water temperature mixing, macroporosity, economic efficiency, technical and economic assessment.
