Description

Detailed Description of the Invention

The present invention relates to a pavement construction method on the surface of earth and sand around a promenade, park, house, facility, etc., and dry and solidify promoting material, foundation reinforcing material, surface watering, surface pavement material on the surface of the earth and sand. The present invention relates to a construction method in which rolling and surface finishing are performed, a pavement surface (solidified portion) is formed, and the construction period is shortened by simplifying the process, the effect of suppressing the heat island phenomenon, and natural dressing.

The promenade, parks, houses, gardens, and facilities are mostly unpaved, and some of the asphalt and concrete are paved with large machines, so the construction work is complicated and rational. And asphalt concrete pavement has a problem of heat island phenomenon.

Problems to be solved by the invention

Asphalt and concrete construction methods are mainly used around the current promenades, parks, houses, gardens, and facilities. Scouring and removing grass and sand around the boardwalk, park, house, garden, facility, etc., and asphalt, concrete placement, curing To prevent road repairs, mowing, and weeding, but none of them achieve the expected functions, or they are undeveloped or not minded because the construction is complicated and the economy is low. It is in a situation where it is left unattended.

The problem to be solved by the present invention is an excellent technology that performs a landscape protection function such as simple pavement, boardwalk, park, house, facility, etc. required, maintains its continuity, and suppresses heat island phenomenon etc. Is to provide.

The present invention addresses the problems as described above, and its purpose is to provide a construction method that can shorten the construction period and simplify the construction method, suppress the heat island phenomenon, and contribute to global warming. It is.

Means to solve the problem

To fulfill the function as a simple pavement,
(1) Anyone can easily perform construction with human power.
(2) Unevenness correction work can be simplified by spreading the foundation reinforcement.
(3) Partial repair can be done easily.
(4) Naturalness in harmony with the surrounding environment.
(5) Expected to mitigate / suppress the heat island phenomenon.

Resin-based mortar adhesion enhancer (ethylene vinyl acetate copolymer) (powder) is used.
Use of the resin-based mortar adhesion enhancer has an effect of improving the adhesion of the fine aggregate and the adhesion to the lower layer, and improving the bending strength, tensile strength, impact resistance and wear resistance.
The amount of resin-based mortar adhesion enhancer used is preferably resin-based mortar adhesion enhancer (1-10) parts by weight per 100 parts by weight of fine aggregate.
If the amount is too small, the intended effect cannot be obtained.

As the base reinforcement, waste glass powder aggregate and cement mixture are used.
The use of a mixture of waste glass powder aggregate and cement can be expected to strengthen the foundation support and dry and solidify the surface pavement material due to the heat of solidification of the cement.
In addition, waste glass has almost no adhering moisture, can eliminate the drying process, and can contribute to recycling.
The base reinforcing material is preferably cement (10-30) parts by weight with respect to 100 parts by weight of waste glass powder aggregate.

The dry solidification accelerator is a mixture of powdered quicklime and cement.
The use of a mixture of powdered quicklime and cement generates heat by reacting with moisture in the soil, can maintain heat retention for a long time, and can be expected to promote drying and solidification from the back side of the surface pavement material.
The dry solidification promoting material is preferably powdered quicklime (10 to 50) parts by weight with respect to 100 parts by weight of cement.
When there is too much powdered quicklime, heat generation expands and rises in the surface pavement and cracks occur, and when it is too small, the heat generation temperature is low and the effect is small.
