This invention relates to a new idea in environment friendly rubber tiles of long durability.
This invention of rubber pavement tile is an absolutely novel idea. Nobody else has thought of the possibility of manufacturing pavement tiles with rubber. The pavement tile in rubber has flexibility and will never brittle and will withstand uneven surface load as it is unbreakable and as such it will not cause and damage to the users and vehicles which moves over it.
PRIOR ART:
At present ordinary and common Pavement tiles are manufactured in Concrete. Ordinary and common concrete pavement tile is brittle and has no flexing property to withstand uneven surface load and breaks causing injury to users and difficulties to vehicles which moves over it. The collection of moss especially in winter season makes the concrete tiles slippery and skidding. Concrete debris generated from breaking down of concrete pavement tile is becoming a serious threat to the environment since it is not recyclable. It will adversely affect the virginity, fertility and water penetrating power of the soil.
SUMMARY OF THE INVENTION
According to the present Invention, the aforesaid problems are solved. The advantages of the present invention is that the high tensile strength, hardness and abrasion resistance makes the Flexi Intermeshing Rubber Pavement Tile flexible and unbreakable even if uneven loads are applied. Since it is manufactured in Rubber, collection of moss will not happen even in rainy/winter season. It has an antiskid projection like button or dumbbell design which can be in different designs at the top surface to prevent skidding, in addition to its inherent antiskid property, even in wet condition. This particular design eliminates entrapment of dirt and makes it easy to clean. The edges of each Flexi Intermeshing Rubber Pavement Tiles are

shaped in 5mm sloping down so as to permit water to percolate into the earth there by keeping the top surface always dry. In addition it promotes the storage of underground water.
The hollow space provided at the bottom saves material and facilitates the self fixing to the ground. Only natural materials (sand, rock powder etc) are required for its laying. Usually a layer of 50mm thick fine sand or rock powder can be used as the bed for laying. If extra strength is required, the cavities can be filled with rock powder.
Flexi Intermeshing Rubber Pavement Tiles are environment friendly as the mass is lesser than concrete pavement tiles. Absorption of heat will be lesser and there will be less environment heating compared to concrete pavement tiles. The hollow space in between the tile and earth prevents earth from heating up even in very hot summer.
Due to the resilient property of rubber it gives much comfort and durability to the equipments which moves over it. It also helps reducing sound pollution due to its cushioning property.
Compared to the existing tiles in concrete the light weight or rubber tiles makes it less expensive in transportation, laying and dismantling. Since natural materials are used for its laying in case of shifting the tile to another location the land will remain as good as a virgin land. The dismantled tile will be as good as new tile and less care is required in handling as these tiles are unbreakable.
In another form of the invention, the intermeshing tile can be laid with interlocking system beneath the top surface. This is for sloppy surface and for overcoming extra ordinary torque experienced during breaking and starting of a motor vehicle.

This product is/can be manufactured in different unfading and u.v resistant colours, and different thickness from 25 - 55mm in size 190x190mm by applying a specific pressure 9 Kg/cm2 at 150° C. This high pressure moulding increases its load bearing capacity. This product consists of two different types of rubber compounds moulded together in a three piece mould. The top coloured /black compound is specially formulated to meet U.V resistance, abrasion resistance and high tensile and tear resistance with the following specifications.
(A) Hardness - 75 to 85 ° Shore A
(B) Tensile Strength - 6 to 9 MPa
(C) Abrasion Loss - 300 to 500 mm3
The Lower portion is made of a less costly black coloured rubber compound with the following specifications
(A) Hardness - 75 to 85 ° Shore A
(B) Tensile Strength - 4 to 6 MPa
(C) Abrasion Loss - 500 to 700 mm3
DESCRIPTION:
Brief Description of the accompanying Drawing :
FIG -1 Shows top surface design. It is dumb-bell in shape, 22 xlO size, and 3mm thick. The edges are of R2 radius. These dumb - bells are distributed one against another in opposite direction. FIG -2 Shows detailed drawing of the bottom surface. The ribs and borders are of 12mm width and 22mm high. Top surface design is 3mm high and the solid portion below is 5mm thick. Overall thickness is

22+3+5 =30 mm. This can vary from 25 to 55 in other models. Over
all size of tile is 269 xl90 mm and the effective surface area is
190 xl90mm. Radius at the curved surface is R 134.
FIG-3 Shows how the tiles are intermeshing each other.
FIG-4 Shows another modification of intermeshing tile with interlocking
system showing the top surface view. FIG-5 Shows male and female connections (A & B) of interlocking system
from the bottom.
Detailed Description of the illustratd embodiments:
Referring to Fig I - The antiskid button or dumbbell or any other design makes it an antislip product even in rainy season. The surface profile is so designed that all the water falls on the tile drips down to the earth through the sloppy edges of the tile. It is designed without any sharp corners to avoid agglomeration of dirt on the surface. The designs are made in such a way that once the tiles are laid together, there is continuity of design pattern.
Referring to Fig 2 - The hollow space provided at the bottom gives additional cushioning, absorbs sounds, reduces material and insulates the soil from getting it dried. This particular design with cavity at the back reduces weight which have positive impact on price, transportation, labour cost and environment. The ribs are tapered towards the bottom to facilitate easy de moulding during production. In case very high load bearing capacity is required, the voids can be filled with cheap materials like sand or rock powder. The ribbed structure at the bottom keeps it firm on the ground without moving.

Figure 3 shows, How Flexi Intermeshing Rubber Pavement Tiles are laid.
Figure 4 shows detailed dimensions of dovetail shaped projections which goes beneath the undercut of the adjacent tile shown as B in FIG 5, locking them together. This helps the whole assembly of mats to behave as a single mass and oppose any lateral or upward movement of tile under a very heavy unexpected external force.
Figure 5 shows the positions of male "A" and female "B" connectors with their dimensions.
4. CLAIMS.
I claim:
1. That the present invention of Flexi Inter Meshing Rubber Pavement Tile is an absolutely novel idea since the pavement tiles is manufactured in Rubber with the qualities of high tensile strength, hardness, and it is unbreakable and flexible. Over and above the inherent anti-skid property of rubber, my invention has an anti-skid quality because of the button-like/ dumbell etc designs on the surface of the tiles.
2. The Rubber pavement tiles have got high abrasion resistance even if uneven loads are applied.
3. Unlike the pavement tiles in concrete, Rubber pavement tiles have got the advantage of not getting moss collection even during rainy or winter season.
4. Rubber pavement tiles as invented by me can be manufactured in different sizes, measurements and designs to suit different purposes as per requirements.

5. The rubber pavement tiles can be laid upon sand or rock powder bed evenly without using any adhesives and it can also be replaced or removed/dismantled and relocated without causing any damage to the environment as well as the tiles. The hollow space provided at the bottom of the rubber tiles makes it self fixing to the ground. Thus the laying cost and subsequent maintenance is very minimal.
6. The sloping at the edges of the pavement tiles permit rain water to percolate into the earth through the gaps in between the tiles. Thus it will facilitate the under water storage and it is environmental friendly.
7. The mass of the flexi intermeshing pavement tiles is lesser than the
concrete pavement tiles and absorption of heat will be lesser and
there will be less atmosphere heating than the concrete pavement
tiles.
8. Colours used in present concrete tiles are only a surface coat and
abrades away after repeated use. Where as in flexi rubber tile the
entire top surface of 8mm is with U.V resistant colour and the colour
doesn't fade during its life time.
9. The said rubber pavement tiles can be recycled and affordable. These
can be used in the court yards of Schools, hospitals, health centres,
playgrounds, houses etc.. as probability for suffering grave injuries to
human being or animals is very minimal compared to the concrete
pavement tiles.
