METHOD OF MAKING CONSTRUCTION BOARDS Russian patent published in 2016 - IPC E01C5/20 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular, to processes of making construction boards based on polymer materials of various functional purposes. Method of making construction boards involves using extruded from a thermoplastic polymer long hollow rectangular type modules, which in lines are arranged on the base with serial connection of adjacent modules at side faces oriented in the direction of longitudinal-vertical planes, parallel to the respective symmetry plane of the module, formation of working surfaces of plates along the edges of adjacent modules, which are oriented in the direction of longitudinal horizontal planes parallel to the base. Working width of the formed plate is set at a total amount of laid onto the base hollow modules, and through hollow spaces of the modules or part of the said spaces are filled with a porous foamed polymer material. Herewith for filling the hollow spaces of the modules a porous foamed polymer material is used, density (p₁) of which is equal to (0.02-0.35)p₂, where p₂ is density of the thermoplastic polymer for making modules of not more than 1,050 kg/m³. Filling of the hollow spaces of the modules with the porous foamed polymer material is carried out on the side of ends of the plates perpendicular to the longitudinal-vertical planes of symmetry of the modules.

EFFECT: technical result is creation of operating and reliable construction boards based on hollow modules intended both for formation of collapsible roads pavements on ground surfaces with complex geological conditions and for use as wall structures.
