ãåã«CAã¢ã«ã¿ã«ãšããã In a slab track, a cement bitumen mixture consisting of asphalt emulsion, cement, sand, water, admixtures, etc. is added to the filled space (hereinafter simply referred to as the filled space) formed between the upper and lower parts of the foundation and the track slab. A buffer layer is provided by filling it with a mixture (usually called cement asphalt mortar, or CA mortar for short). The hardened buffer layer of this cement bituminous mixture has appropriate strength and elasticity, and serves as a buffer layer that absorbs and disperses load shock, vibration, etc. Hereinafter, the cement bituminous mixture and its hardened product will be simply referred to as CA mortar.

èŠæãããŠããã Slab track has the advantage of being easy to construct and eliminating track maintenance work. However, when railways are located in cold regions, the low temperatures and snowfall in winter and the accompanying freezing and thawing effects are severe, so CA mortar, which is conventionally used in warm regions, is more susceptible to freezing and thawing.
There is a demand for more durable materials with greater resistance to melting, impact resistance, and cracking resistance.

èŠãšãããŠããã Additionally, as the years have passed since the slab track has been in service, the exposed parts of the CA mortar layer and the surrounding areas have become cracked, damaged, and weathered, which requires repair.

ããã Although coarse aggregate such as gravel or crushed stone may be used in special cases, fine aggregate is usually used. The fine aggregate has a grain size of 2.5 mm or less and a coarse grain ratio of 1 to 2.5, preferably 1.2 to 2. Examples include river sand, sea sand, mountain sand, silica sand, sintered ash sand, iron sand, and foundry sand. In addition to aggregate, we also produce glass powder, silica sand powder, diatomaceous earth, mica powder, mica pieces, bentonite, clay, stone powder, fly ash, silica anhydride powder, pigments, carbon black,
A filler such as graphite can be used. These can also be used after being dispersed in water. Additionally, colloidal silica can also be used. Further, short fibers such as inorganic fibers, natural organic fibers, synthetic organic fibers, and carbon fibers can be mixed within the range that does not impair the filling properties of the CA mortar.

ãŠããã CA mortar is made with the following mixing ratio, for example. 0.1 to 5 parts of bituminous emulsion (converted to 60% by weight of evaporation residue), 0 to 6 parts of aggregate (as sand), per 1 part by weight of cement (hereinafter simply referred to as parts);
It is usually used in a proportion of 0 to 2 parts. When using cement shrinkage compensators, hardening accelerators, etc.
Calculate by including the amount of cement in the above mixing ratio. Water is used as necessary, considering the workability of CA mortar. When using a blowing agent,
For example, when using aluminum powder,
It varies depending on the amount of air bubbles introduced into the CA mortar, but generally 0.005 to 0.02% by weight of the cement amount.
used within the range. If the amount of bituminous emulsion is less than 0.1 part per part of cement in the above-mentioned mixing ratio, the stiffness of the cured product will be strong, the elastic modulus and flexibility will be insufficient, and the waterproofness will also decrease. When the bituminous emulsion exceeds 5 parts, the strength decreases significantly. Further, when the amount of aggregate exceeds 6 parts of aggregate per 1 part of cement, workability such as filling properties of CA mortar decreases. Those that do not use aggregate have good filling properties, and have excellent freezing and melting resistance.

In addition, these spacers 5, 5... are fixed in advance by sewing, gluing, etc. to the installation position of the reinforcing body 4 formed into a sheet shape, and furthermore, when forming the reinforcing body 4 into a sheet shape, , if it is configured as one piece, construction becomes easier.

When filling with mortar, apply a prime such as bituminous emulsion, cement paste, rubber latex, polymer emulsion, or a mixture thereof, or epoxy resin to the areas in contact with the CA mortar, such as the back surface of the base 1 and track slab 2. It can also be coated. In addition, a reinforcing body 4 formed in a sheet shape and a spacer 5 are also provided.
It is also possible to soak it in an aqueous cement dispersion, a bituminous emulsion diluted with water, or a mixture of both, drain the water, and then place it in the filling section. Also,
A light vibration can also be applied to the filling of CA mortar.

ãã(4) Since the present invention inserts a reinforcing body formed in a sheet shape into the filling space and also interposes a spacer, it is necessary to use a spacer to maintain the distance between the reinforcing bodies formed in a laminated sheet shape. This makes it possible to easily and reliably fill the space between the pine-shaped reinforcement bodies with CA mortar, maintain the installation position of the pine-shaped reinforcement bodies well, and make it possible to exert the reinforcing effect of the CA mortar layer equally in each part.
