Mobile expandable polystyrene road structure production complex

The article addresses the plan of development of a mobile expandable polystyrene road structure production complex. It is necessary to build roads on soils with low bearing capacity in order to ensure the transport accessibility of agribusiness facilities. The proposed solution could be used for the organization of rapid repairs of roads and highways, for eliminating the negative effects caused by natural disasters and other emergencies, for building roads in the arctic zone and ensuring stable functioning of roads in war time. An optimal composition of the process equipment for the mobile expandable polystyrene road structure production complex considered a Plan of construction of a light embankment using EPS-blocks and schematic of an embankment circuit device in various conditions using XPS-plates. The dependence of the time of delivery of the EPS-block objects from the remoteness of construction and feasibility study shows the effectiveness of the use of mobile complexes.

First Time

The aim of the publication is to determine the prerequisites of and to elaborate on the foundations of the Exclusion Zone reintegration in order to address the issue of rational development of urban-planning documentation complex regarding the legitimacy of said territory exploitation. It is established that for the implementation of the «Radioactive waste management strategy» the production complex «Vector» is being constructed on the Exclusion Zone territory; a powerful park of renewable energy generation is being created to implement the «Chornobyl - a Territory of Change» strategy; a Chornobyl Radiation-Ecological Biosphere Reserve was established to support and increase the barrier function of the zone; in order to promote the Safe Chornobyl brand-name, the tourist traffic is being increased and the conditions for the visitors are improving. In the absence of developed and approved city planning documentation, the listed above causes the problem of legitimacy and rationality of the exclusion zone territory use. The paper for the first time raises the question of the need to elaborate the concept of functional planning of the Chornobyl NPP exclusion zone territory and the development of the design-planning complex (urban planning documentation): from the territory.

Because the aerogel has ultra-low density and good impact resistance, the aerogel material, epoxy-hardener system, and expandable polystyrene beads (EPS) were used to prepare the lightweight aerogel reinforced hollow epoxy macro-spheres (AR-HEMS). The multi-phase epoxy syntactic foam (ESF) was manufactured with the epoxy-hardener system, HGMS (EP-hardener-HGMS), and AR-HEMS by “the compression modeling method.” In this experiment, in order to enhance the strength of the ESF, some different kinds of the carbon fiber (CF) were added into the EP-hardener-HGMS system (CFR-EP). The influence of the volume stacking fraction, inner diameter, and layer of the AR-HEMS and the content and type of the CF in the EP-HGMS (CFR-EP) system on the compressive strength of the ESF were studied. Weighing the two factors of the density and compressive strength, the ESF reinforced by 1.5 wt% CF with 90% AR-HEMS has the better performance. This kind of the ESF has 0.428 g/cm3 nd 20.76 Mpa, which could be applied in 2076 m deep sea.
