摘要： PURPOSE: To make easily portable because of being lighter than a board-shaped resin board, to easily connect by utilizing meshed fabrics of the net, to provide a reinforcing structure excellent in permeability for a road floor and weak ground, and also to reduce the occurrence of buoyency due to water and deposition of crushed stone, so that the cushionability being the characteristic of the net can be added, the retainability of crushed stone or the like that has been filled in an opening part can be improved, the durability can be enhanced while reducing the damage to the resin net due to crushed stone or the like, the stability of the road floor can be achieved for a long period of time, and the control of the crushed stone layer after construction can be facilitated. CONSTITUTION: Band-shaped resin nets 11, 12 of the nearly same width are superposed, and then the respective band-shaped resin nets are joined each other at prescribed intervals 12a, 12b, 12c in the longitudinal direction, and further another band-shaped resin net 13 of the nearly same width is superposed, and the adjacent band-shaped resin nets 12, 13 are joined each other at the intermediate points 13a, 13b of the respective joining places. By repeating these series of work procedure, a road-floor reinforcing structure can be formed.

摘要： PURPOSE:To increase bonding strength with a material to be covered by coating or laminating thermoplastic synthetic resin sheets on the rear face of a towel having a number of monofilament projections on its surface and compounding integrally the thermoplastic synthetic resin sheets. CONSTITUTION:A composite sheet for covering consists of a towel 10 having a number of loop-shaped projections 20 on its surface 10a and thermoplastic synthetic resin sheets 30 to be compounded integrally on a rear surface 10b of said towel 10 by coating or laminating. The surface of a material to be covered before solidified is covered facing the towel side 10 by a composite sheet for covering. At that time, a number of loop-shaped projections 20 formed on the surface of the towel are in the state of being buried under said covered surface. After that, said covered material is solidified to fix the loop-shaped projections 20 in the buried state without using a bonding agent, and therefore, bonding strength for not only two-dimensional bonding of said covered material and composite sheets 30 for covering but also three-dimensional bonding including projections can be provided and enhanced to increase the bonding strength with the covered material.
