摘要： PURPOSE:To shorten execution time without requiring any cooling process and improve workability, durability, waterproofing quality, etc., by using, for a surface layer part, a laminated body made of a rubber based sheet and reinforced plastic or reinforced hard rubber panel. CONSTITUTION:An uneven surfaces are formed respectively on a rubber-based sheet 2 having flexibility and elasticity, and a panel 3 made of glass fiber reinforced plastic like FRP. Next, a composite laminated layer body 4 is formed chemically by enmeshing uneven parts of the sheet 2 and panel 3 with each other, and forming a junction layer 5 on their joint with an adhesive or a pressure sensitive adhesive, or physically fastening them with screws 6. A laminated layer body 4 is laid out over a base layer part A made from concrete or the like by placing rectangular molded products as they are, cutting them up into specified sizes at site, or spreading out flat a roll of long length.

摘要： PURPOSE:To properly control a pot life and a curing time and to cure the subject resin by using a mixture of an amine-based compound with an amine activity adjusting agent as a reaction initiator and curing an epoxy resin monomer with a polymercaptan-based curing agent. CONSTITUTION:In curing an epoxy resin monomer with a polymercaptan-based curing agent (preferably ether type polymercaptan), a mixture of 100 pts.wt. amine-based compound [e.g. tris(dimethylaminomethyl)phenol or N- methylpyrrolidine] and 1100 pts.wt. amine activity adjusting agent (e.g. carboxylic acid including acid anhydride as a curing retarder or organic acid comprising phenol as curing promoter) as a reaction initiator is added to the curing system to carry out the objective curing.

摘要： PURPOSE:To inhibit a reaction of alkali and aggregate and to prevent a crack, peeling and spalling of concrete by sticking asphalt to aggregate main body. CONSTITUTION:This aggregate A is obtained by sticking asphalt 2 to aggregate main body 1 such as gravel, crushed stone and sand. As this aggregate A, not only the whole body of aggregate 1 is coated by asphalt 2 as shown in a figure but also one part thereof is similarly coated by asphalt. When concrete obtained by kneading aggregate A with cement paste is placed, asphalt 2 stuck to the aggregate main body 1 functions as a protective layer for inhibiting reaction of alkali and aggregate. Therefore a crack, peeling and spalling of the placed concrete can be prevented. Further waste material obtained by cutting the existing asphalt paving part can be intactly utilized as the aggregate A. Therefore this aggregate A is easily produced and also fills the role of treatment of the above-mentioned waste material.

摘要： PURPOSE:To perform an ideal semi-rigidified paving, shorten execution time and reduce costs by re-utilizing aggregates recovered from asphalt pavement, performing the processes of recovered aggregate production, application of binding agent and pavement in that order. CONSTITUTION:Paving is conducted by performing in turn the processes of ripping the existing asphalt pavement and manufacturing recovered aggregate A with asphalt 2 adhering to aggregate 1, first, applying a reactant type bonding agent 3 to the recovered aggregate A, next, and paving with the recovered aggregate A with the reactant type bonding agent 3 adhering to it. The work may be executed in the five processes of recovering massive substance, producing recovered aggregate, applying main agent, mixing hardening agent and executing paving. Semirigidification is accelerated by adopting a construction in which plastic portions consisting of asphalt 2 are inserted among aggregates 1 without fail. This method makes it possible to speedily open for traffics, solve the problem of disposing recovered aggregate and apply to site mixing method and plant mix method.

摘要： PROBLEM TO BE SOLVED: To provide ideal semi-rigid pavement by paving by adhering a reactive binder on a collected aggregate produced by scratching and loosening an existing asphalt paved part. SOLUTION: A collected aggregate A with asphalt 2 adhered on an aggregate 1 of gravels, etc., is produced by scratching and loosening an existing asphalt paved part. Thereafter, the collected aggregate A and a reactive binder 3 are uniformly mixed by spraying the reactive binder 3 of super-high speed strong cement or thermosetting resin while stirring the collected aggregate A, and this mixture is paved. As a plastic part consisting of the asphalt 2 is certainly interposed between the aggregates 1 on this paved body, a semi-rigid property of a paved part is promoted by the asphalt 2, the semi-rigid property is stabilized and strength excels a conventional semi-rigid pavement. Consequently, it is possible to extensively shorten a construction period of time and to speedily clear traffic, and as a large amount of the collected aggregate is used, it is possible to reduce construction cost.

摘要： PURPOSE:To let paved roads have water permeability and contribute to the preservation of environment such as the prevention of reduction in the amount of underground water and afforestation by forming water permeable parts in the surface layer parts consisting of a rubber-based sheet and plastic or reinforced and rubber panel. CONSTITUTION:A rugged surfaces with alternate troughs and ridges are formed respectively on a rubber-based sheet 2 with flexibility and elasticity, and a panel 3 consisting of glass fiber reinforced plastic like FRP. Next, a surface layer part B consisting of a composite laminated layer body 4 is formed chemically by enmeshing respective concavo-convex parts of the sheet 2 and panel 3, and forming a junction layer 5 on their joint with an adhesive or a pressure sensitive adhesive, or physically fastening with screws 6. The surface layer part B is firmly fixed over a base layer part A, and water permeable holes 8 reaching down to the base layer part A are drilled at required locations on the surface layer part B to let paved roads have water permeability to eliminate the formation of water pools.
