Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-permeable pavement structure which is excellent in weather resistance and flexibility and can be constructed for a short period of time, and a construction method thereof.

[0002]

2. Description of the Related Art A pavement structure prepared by laying a mixture of an aggregate having a large particle size and a binder on a base substrate and curing the binder has a large number of voids,
It is generally called a water-permeable pavement structure because it allows water such as rainwater to permeate from its surface to the foundation substrate. Also,
The water-permeable pavement structure using natural stones of various colors as the aggregate is called natural stone pavement, and because of its beautiful appearance, it is not only a park landscape road and promenade, but also a bus lane and a cycling road. , It is also used for road pavement such as arcade roads.

[0003]

Epoxy resin compositions and emulsion resin compositions have been conventionally used as binders for the above water-permeable pavement structures. However, these resin compositions have the following problems.
That is, the epoxy-based or emulsion-based resin composition requires a long time for curing and curing. Therefore, there is a problem in that the construction of the conventional water-permeable pavement structure using the same also takes a long time. Further, since the epoxy resin composition and the like have poor curability at low temperatures, there is a problem that it is difficult to construct the water-permeable pavement structure in winter. A water-permeable pavement structure using the above resin composition has poor weather resistance and has a problem that it becomes brittle due to natural conditions such as wind and snow and sunlight. Furthermore, since the conventional water-permeable pavement structure using the above resin composition is poor in flexibility, even if the base substrate is thermally expanded, it cannot follow this movement, and damage such as cracks or cracks occurs. There is a problem of doing.

In order to solve the above various problems, it has been proposed to apply an acrylic resin composition used as a floor or wall coating material, a road marking material, and a paving material (Japanese Patent Laid-Open No. 58-196268). Gazette). This acrylic resin composition is a resin composition composed of a solution in which a polymer containing an acrylic resin as a main component is dissolved in an acrylic acid ester monomer or a methacrylic acid ester monomer, paraffin wax, a plasticizer, etc. It is commonly called acrylic syrup because it is transparent. This acrylic resin composition has a short curing and curing time and is excellent in curability at low temperatures. Since this acrylic resin composition has a strong adhesive force, the coated body and the pavement structure obtained by using the acrylic resin composition have excellent abrasion resistance and weather fastness, which are the characteristics of the acrylic resin. Therefore, it has been expected that a short time construction of a water-permeable pavement structure having excellent abrasion resistance, weather fastness and flexibility using this acrylic resin composition. However, since this acrylic resin composition is anaerobic curable, it has the property that the curing reaction becomes worse in the presence of air (oxygen). Therefore, as described above, paraffin wax is added to avoid air (oxygen) contact, but in the thin film layer, the air blocking effect is insufficient and the curing reaction is poor, and especially when the amount of aggregate is large ( The amount of entrained oxygen) increases, resulting in poor curing. Therefore, in the construction of the water-permeable pavement structure, since a large amount of aggregate having a large particle size is used as described above, the contact area between the acrylic resin composition (binder) and air (oxygen) is generally It becomes significantly larger than the road pavement structure, and even if the mixture of the above acrylic resin composition and aggregate is laid on the base substrate, the acrylic resin composition between the aggregates does not cure sufficiently and the water permeability. There is a serious problem that the pavement structure cannot be constructed. In order to solve this problem, application of an acrylic resin composition in which a vinyl ester resin and an air-drying unsaturated resin (air-oxidizing unsaturated resin) are dissolved in an acrylic acid ester monomer or a methacrylic acid ester monomer has been proposed. (JP-A-5-9245). This acrylic resin composition,
Due to the introduction of the air-drying component, the anaerobic curability is very small, and it has an excellent property of being completely cured even in the presence of air (oxygen). Therefore, by using this acrylic resin composition as a binder of aggregate,
The problems of weather fastness, abrasion resistance, moist heat resistance, low temperature flexibility and durability will be solved. However, this method
The following new problems occur. That is, the weight ratio of the acrylic resin composition and the aggregate (including the fillers, the same applies hereinafter) was calculated as follows: aggregate / acrylic resin composition = 9 or more,
Especially when it is 9.5 or more, the curability and workability such as laying are deteriorated. When the weight mixing ratio is less than 9, the water permeability of the pavement structure obtained may be insufficient, or the water permeability may be sufficient at the beginning of construction, depending on the particle size, shape and type of aggregate. Sand, mud, dust, etc. will be clogged between the aggregates and water permeability and durability will be reduced in a short period of time.

The present invention has been made in view of the above circumstances, and is excellent in workability at the time of construction, has a short curing time and curing time, and is excellent in weather fastness, flexibility, and low temperature curability. The purpose is to provide a permeable pavement structure and a construction method thereof.

By adding a thixotropic agent to the product, it was found that the curability and workability are excellent even if the weight mixing ratio of the aggregate and the binder is 9.5 or more. When a water-permeable pavement structure is constructed in the presence of air (oxygen) using a special acrylic resin composition containing this thixotropic agent, the construction time is significantly shortened and the resin composition liquid It was found that the liquid drop (flow) was suppressed, the porosity between the aggregates was increased, and the water permeability was significantly improved.

The mixing ratio of (component) is appropriately determined according to various conditions at the time of construction of the water-permeable pavement structure, but in general, A component to
0.1 to 20% of the total C component, preferably 0.2 to 15
%, Particularly preferably 0.3 to 10%. That is, the component (C component) having the air oxidation function is 0.1%.
If it is less than the above range, it may take a long time to cure and form the thin film layer, or the film may become uncured. Conversely, 20
This is because if it exceeds%, the cured physical properties and flexibility tend to deteriorate.

Next, the thixotropic property imparted by the thixotropic agent (component D), which is a characteristic component of the present invention, will be described. As described above, in a water-permeable pavement structure, even if a resin composition including a vinyl ester resin or a polymerizable unsaturated monomer into which a component having an air oxidation function is introduced is used as a binder, the amount of aggregate is large. If so, poor curability occurs. Therefore, it is impossible to obtain a water-permeable pavement structure having sufficient water-permeability and having no decrease in water permeability over time. The present invention solves this problem by a technique of imparting thixotropy to a resin composition. Specifically, a thixotropic agent is blended in the resin composition. That is, by imparting thixotropy to the resin composition (binder), dripping is prevented, and curability is not hindered even if the blending ratio of the aggregate is greatly increased. It is not clear why the prevention of curing failure does not occur if this dripping is prevented,
It is guessed as follows. That is, when the resin composition (binder) drips, the amount of the resin composition between the aggregates is reduced, and an ultra-thin film portion is generated.
It is considered that the ultra-thin film portion is insufficiently cured or uncured under the influence of. Furthermore, due to the dripping, in the resulting water-permeable pavement structure, the amount of the resin composition in the thickness direction becomes non-uniform, resulting in a portion with few variations in strength or voids, insufficient water permeability, or short-term after construction. It is considered that the water permeability decreases due to clogging between the two. Therefore, it is presumed that if the resin composition is prevented from dripping by imparting thixotropy, these inconveniences are solved and a water-permeable pavement structure excellent in required properties can be obtained.

The thixotropic property imparted to the resin composition is generally expressed as a thixotropic index value (TI value).
2-10, preferably 2.5-9, particularly preferably
It is adjusted to the range of 3 to 7. If the TI value is less than 2, there is a possibility that the weight mixing ratio of the aggregate and the resin composition (binder) cannot be set to a high compounding ratio of aggregate / binder = 9.5 or more. If this is forcibly made to be a high compounding ratio of 9.5 or more, the water permeability of the obtained pavement structure tends to be poor, and problems such as strength reduction and variation of the pavement structure will occur. . On the other hand, when the TI value exceeds 10, the viscosity tends to be too high and the workability tends to be poor. As described above, the thixotropic property is imparted by adding the thixotropic agent (component D) to the resin composition. This composition may be compounded in advance before construction, or may be compounded during construction. The thixotropic agent (component D) is not particularly limited, and examples thereof include silica powder such as Aerosil, surface-treated fine particle silica, asbestos and caviolite, polyamide organic thixotropic agent, amino-treated clay, fly ash. , Carbon powder, etc. Among these, Aerosil,
Surface-treated fine particle silica and a polyamide-based organic thixotropic agent are preferable. The thixotropic agent is blended in such a proportion that the TI value falls within the above range, and the blending proportion is appropriately determined depending on the kind of the thixotropic agent. Generally, it is in the range of 0.5 to 15%, preferably 1 to 12%, particularly preferably 3 to 10% of the total resin composition.

Further, an appropriate amount of additives such as an ultraviolet absorber, an antioxidant, a polymerization inhibitor, a self-leveling agent, a coloring agent, a defoaming agent and paraffin wax is added to the resin composition of the components A to D. It can be blended.

Next, in acrylic syrup, etc.,
Usually, a polymerization initiator is used, but also in the present invention,
A polymerization initiator is used to cure the resin composition composed of the components A to D.

As the above-mentioned polymerization initiator, a redox catalyst composed of a curing agent and a curing accelerator is usually used. Further, the type of this Redox catalyst is not particularly limited, and various types can be used. The polymerization initiator may be in the form of powder, paste or liquid.

The curing agent that is a constituent of the redox catalyst is not particularly limited, but it is preferable to use an organic peroxide. Examples of the organic peroxide include diacyl peroxide type, peroxy ester type, hydroperoxide type, dialkyl peroxide type, ketone peroxide type, peroxyketal type, alkyl perester type, percarbonate type and the like. . These organic peroxides are appropriately selected and used according to various conditions at the time of construction of the water-permeable pavement structure such as kneading conditions and curing temperature. Among these, it is particularly preferable to use benzoyl peroxide surface-treated with an inorganic powder containing water of crystallization. Examples of the inorganic powder include dicalcium phosphate, calcium sulfate, magnesium carbonate, aluminum hydroxide and the like. In order to avoid the risk of handling these organic peroxides, a paste or a liquid diluted with an inert liquid or powder to a concentration of 50%, preferably 35% or less, and particularly preferably 30% is used. It is preferable to use a powdery material.

The curing accelerator, which is another constituent of the redox catalyst, is not particularly limited, but may be a tertiary amine, a quaternary ammonium salt, or a metal such as cobalt, vanadium or manganese. The metal soap etc. which it has are mentioned.

As the tertiary amine, it is preferable to use one in which at least one aromatic residue is directly bonded to the nitrogen atom. Particularly preferably, N'-dimethylaniline, N, N'-dimethyl-p-toluidine, N,
N'-dihydroxyethyl-p-toluidine, N, N '
-Di-2-hydroxypropyl-p-toluidine and the like. These may be used alone or in combination of two or more.

The mixing ratio of such a polymerization initiator is appropriately determined according to various conditions at the time of construction of the water-permeable pavement structure, particularly the temperature, but it is generally diluted to 30% and the component A is used. To 0.5 to 15%, preferably 1 to 12%, and particularly preferably 2 to 10% of the entire C component. That is, when the polymerization initiator is less than 0.5%,
This is because it tends to take a long time to cure and the purpose of rapid curing cannot be achieved. Conversely, if it exceeds 15%,
This is because the curing tends to be too fast and the construction work tends to be difficult, and the cost tends to increase.

Next, a method for constructing the water-permeable pavement structure of the present invention will be described.
