METHOD FOR CONSTRUCTION OF FLOATING BODY OF ROAD Russian patent published in 2015 - IPC E02D17/18 

FIELD: construction.

SUBSTANCE: invention relates to the construction of highways, and is intended to create the permanent roads on weak swampy subgrades. Method for construction of the floating road body includes application of liquid layer of the foamed polymeric material of predetermined width on the surface of the weak subgrade, on the surface of which formed after polymerisation, the reinforcing geosynthetic material is placed, then the process of stacking of layers is repeated as many times as necessary till the achievement of the required height and geometry of the floating body of road. After that, the road body from the foamed polymer material is filled with mineral soil with thickness not less than 0.3 m. Road pavement is constructed, bottom layer of which is strengthened by cementing. The total height of the bottom part of the road body from the foamed polymer material h_p and height of the upper part from mineral soil together with the road pavement h_mp is determined from the given relationship.

EFFECT: increase of the load-bearing capacity, reduction of materials consumption.
