Smart roads and Intellectual transport system
In the article there are review and compilation of nation and international expirience on the implementation of Intellectual transport system (ITS) in modern project "Smat roads". The following investigations are particularly considered: sun bataries SmartRoad, piezoelectric generators, special paint coatings, etс. We made some suggestion about implementation of "smart kilometer", sun pond, etc. We present the classification of ITS operating parameters divised in two main groups: safety (comfort) and energy efficiency. We selected actual papers at the moment, when this article went to press.

Strongly reinforced concreting design of cast concrete alloy mixtures
The article presents the research of cast concrete mixtures made in the laboratory of the department. Studies have shown the effectiveness of producing molded concrete consistency by the use of additives superplasticizer, for example C-3 and the air-entraining additives LHD in the complex. In this paper the classification of structures and buildings, which would be applicable cast concrete. Also in the paper we conclude that under certain of cast concrete characteristics of the concrete mixtures can be similar to self-sealing. Selfsealing and possible replacement cast mixtures is the most inexpensive. Proposed and proved the applicability of the method of concreting pressure lower-riser to cast and self-compacting concrete.

Approbation of alternative polymeric coagulants to eliminate turbidity of model surface water
Performance to remove turbidity was studied in model waters for five coagulants: ferric chloride, alum, polyaluminum chloride, polyferric sulfate and polyaluminum chloride ferrous. In waters with high turbidity (100-300 NTU) performance of coagulants are similar (over 90%). Polymer coagulants showed better performance and low optimal dosages in waters with low turbidity (10 NTU). In general, polyferric sulfate showed better performance in removal of turbidity.

The method and computation of air change required for attic rooms
The article deals with the recommendations how to eliminate ice dam formation on pitched roofs of the buildings with cold attics during heating period. The case of how to calculate required air change in cold attic rooms, where building structures which separate attics from rooms or utilities with high temperature (heat supply sources) are not insulated, is given in details. It is proved that natural ventilation system can ensure this condition only within short terms. It is necessary to both carry out works to ensure air change and insulate building envelopes, which separate cold attics from rooms with higher air temperature in order to satisfy all the requirements to eliminate reasons of ice dam formation on roofs.

Porous material modeling with finite element method
Wide use of various porous materials in construction engineering applications requires development of up to date methods of non-destructive characterization and optimization of such materials. This work explores an approach to effective elastic modulus calculation of a brittle porous material. Available 3D digital data on the specimen geometry is converted into finite element uniform mesh consisting purely of elements of cubic shape. The resolution limit is determined that allows for analysis of effective properties of porous materials without a significant loss of accuracy. This should facilitate resolving the question on the representativeness of the specimens considered and also increase the speed of the solution process for similar tasks. The approach described can be used for modeling of uniform construction materials, also materials with inclusions under the assumptions of geometrical and material linearity.

Effective models of public-private partnership in municipal facilities
Russian housing facilities services are in critical condition. Modernization requires over 9 trillion rubles. Currently the state has no such funds, and according to plan from all sources during the period 2010-2020 it is planned more than 4 trillion rubles. Thus, the government needs to find other sources of funding reforms. The obvious solution is to engage the public-private partnership. However, the municipal facilities are unattractive for business for a number of reasons, described in this article. Therefore, the aim of the article is to search and analyse effective models of public-private partnerships for use in the Russian municipal facilities sector. Actuality of work is conditioned by the fact that the problem is recognized at the state level. The article studies such a financial model for attracting private investment in construction and reconstruction of infrastructure municipal facilities. The results of effective models for use in the construction and reconstruction of municipal facilities is BOLT [construction, ownership, lease, transfer] (not valid for important facilities: nuclear power plants, hydroelectric, etc.) and BOT [building, operation, transfer].

Unconventional cases of the stone vaults
The evaluation of the technical condition of vaulted structures is the principal issue in the survey of historical buildings. It is also important to understand how any thrust system works, and what functions it performs. However, apart from visual inspection it is necessary to make apertures in vaulted ceilings and determine the methods of support. It is also very important to determine the strength characteristics of masonry. Unconventional cases should always be taken into account during the inspection of masonry vaulted structures. It needs to carefully conduct their inspection with the mandatory breaking opening and strength analysis based on numerical simulation before starting of all the reconstruction, restoration and repair. The use of modern program complexes in the simulation, such as Ansys, Abaqus, allows improving the quality of performed work.
