Title: Sub-grade thermo-structural bridge
Inventor: MOROSCHAN CASEY
IPC: E02D3/00
Filed: 2002-07-02
Abstract: The Sub-Grade Thermo-Structural Bridge is intended to be used as a base in the construction of new road and runway/tarmac beds and beds for slab-on-grade structures such as building pads, pedestrian walk ways and the like to prevent or minimise sharp and/or significant differential settlement of the bed and the surface toppings be they concrete, asphalt, gravel or some other surfacing material, due to failure in the sub-grade matrices below the Thermo-Structural Bridge because of inhet weak characteristics due to perma-first, muskeg, ice lensing, organics, and the like. In this invention, after the grade has been excavated and/or graded to its preliminary rough grade, a grid of re-enforcing material, typically synthetic in nature, such as nylon mesh, fibre-glass rods, or other specified re-enforcing material is laid. A high density, two-part, closed cell, hydro-phobic and insulative expanding polymer resin is sprayed over the grid of re-enforcing material to a specified thickness to achieve a contiguous thermo-structural base which will bridge any current and future weak areas in the soils under the Thermo-Structural Bridge. Should the soils under the thermo-structural bridge degrade and/or settle over time, the thermo-structural bridge would continue to support and sustain the specified fills, topping, finishings, and the like comprising the balance of the make up of the bed.
