Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembled road marking tape capable of withstanding the impact of snow removal equipment and similar devices having snow blades sliding on the road surface, and This invention relates to a method for laying road markings on the road surface.

Road signalization technology has greatly developed over the past few years, along with the development of Maukrie John. Such road signaling technology is developed by the present applicant, who has manufactured many road marking materials and equipment for laying them on roads, as well as members, equipment, and laying equipment, and has experience in these operations. J to people
It has gradually improved over time.

t What is the technology for road signalization like this to date?
Technical and scientific publications for complete understanding
In addition to the folded products, there are many international patent publications by the applicant.
Examples include publications in detailed books. These publications have been analyzed and discussed through much rigorous scrutiny.

Among the problems considered and partly solved by the Applicant are the need for passing the marking device in order to keep the markings safe even at night in winter and/or in northern regions. There is something about road markings that can withstand. The object of the invention is to keep horizontal road markings visible, especially at night and in severe weather conditions, such as when passing by snow removal equipment.

According to the present invention, road markings can be made even at night.
The road marking tape with a re-reflective element for visibility is provided with a compressible elastomeric material at least during the installation stage, which elastomeric material is provided with a re-reflective element when passed by the snow removal equipment. A protrusion that is integrally formed with the reflective member and acts as a rail is made to sink down to the surface of the paved road. Therefore, this type of road marking tape is
In connection with the special construction of prefabricated road marking tapes with elastomeric materials, they are referred to as "compression deformation type" or simply as "compression type".

Another object of the invention is to provide a method for laying a prefabricated road marking tape on a road, which can withstand the passage of snow removal equipment.

Traditionally, the problem of making road markings visible at night, in the rain, and in unfavorable weather conditions has not been solved, especially on major roads, despite the considerable costs involved. .

Conventional snow retention devices are primarily constructed of metal or carburized steel and the like, and are designed to withstand the typical wear and tear of driving on paved roads.

Especially in severe weather conditions, with low temperatures and large amounts of snow! It is known that ice forms on surfaces that are particularly hard and slow to melt, even with salt; this high degree of crystallization makes it necessary to use blades made of metal or carburized steel. However, during operation, such blades can destroy or displace optical elements that are used to make road markings more visible at night and in the rain.

For the above reasons, the applicant of the present patent has conducted extensive research and experimentation to improve the systems and components under operation of snow removal equipment. In particular, a prefabricated road marking strip is proposed which is protected against destructive use of snow removal equipment, for example as described in commonly assigned U.S. Pat. No. 4,129,673. According to this technical solution, the optical element is protected against the destructive action of the snow removal device by means of a protruding element which acts as a rail.

Such protrusions provide effective protection for the optical components, especially against rubber blades and low speed metal blades used in urban areas.

However, the particularly important problem with this known example is that
On expressways, snow removal equipment blades tend to slide at high speeds, a problem that remains virtually unresolved.

According to the present invention, these problems are completely solved,
Moreover, by removing hard ice, road markings can be clearly seen at night and in rainy weather, and good adhesion of tires to the highway surface can be obtained.

This solution was obtained mainly on the basis of the claims experience with road marking tapes with re-reflective elements, which can be provided "like a paving stone". Such road marking tape is covered by U.S. Patent No. 38
It is described in the specification of No. 79148. In particular, one prefabricated road marking tape according to the present invention is compressed during use to sink at least partially to the level of the pavement. The compressible part of the road marking tape is a part of the marking tape, which is advantageously bonded to a meltable bitumen brair provided on the pavement.

All road marking tapes are equipped with an optical element known by the applicant of the present patent and are well protected against the action of the blades of snow removal equipment by the method defined by the invention.

According to an advantageous development of the invention, tapes of low thickness are particularly suitable. Such a thin road marking tape is disclosed in the American Congregational Patent No. 4146 by the present inventor.
635 Akira? Disclosed in oil soda. This known example, together with the other known examples mentioned above, is fully cited in order to better understand the ten principles of the present invention.

The compressible material is harmonic steel.
l) Elastomers with or without bonding are manufactured. This elastomer has the ability to be deformed and return to its original shape. This compressible material itself is known. A compressible material capable of withstanding such repeated compressions and resistant to the erosive action of ambient air is formed from a nystomeric material having no hollow portions. In the case of a hollow portion, a recess is formed in the upper surface of the elastomeric material to compensate for the volume reduction. Compressible materials can also be made from elastomeric foams with minimal porosity.

Mainly water resistant and air resistant elastomers.

Dutral Montecani 12 (Dutral m0nte
cati-terpolymer rubber or polysal
It is made from butyl rubber, such as pol-isar butyl from Company Polisar, although other nydistomers are also contemplated.

The foam is best sulfided at high density with closed cells to ensure very good maximum flex crack life.

Since the compression takes place in a very short time, there is virtually no loss in return time.

Foam materials of this type are, for example, AIAG of Cirie (Tu-
It is manufactured as extruded foam rubber by many manufacturers such as rin)). The impact of the snow removal blade is supported by a sectional tape protrusion that acts as a rail as described in the aforementioned U.S. Pat. No. 4,129,673.

These rails are obtained directly from the prefabricated tape manufacturing process, for example by extrusion of thermoplastic polyurethane which is bonded to road marking tape.

Another object of the present invention is to provide a road marking system through which heavy machinery and members for snow removal work can pass. It is also an object to provide a device for carrying out the method of laying a dam on a horizontal road surface.

In this case, the following conventional points are taken into consideration.

1) Traditionally, the cost of the "auxiliary" nidistomer material has been disproportionate to the cost of the road marking tape, which is the main component.

2) Because the elastically compressible material was stored in rolls, its elastic recovery properties were significantly weakened.

According to the invention, the use of an auxiliary compressible part for the part of the tape with the re-reflective element is reduced, and this compressible part can be provided on the road marking tape in the same laying operation.

Next, the configuration of the present invention will be specifically explained with reference to practical examples shown in the drawings.

The road marking tape according to the first embodiment of the present invention, shown in FIG. The signal part consists of a rail and a re-reflective sphere at the top.

In the second embodiment of FIG. 2, the compressively deformable material consists of an elastomer without hollow parts 9;
A space is formed at the top to compensate for the volume reduction.

In the third embodiment of FIG. 3, the material having the upper signal portion is arranged so as to be located below the plane of the paved road, and the upper surface of the rail as the signal portion is flush with the plane of the paved road. It is arranged so that it is located at n.

In the fourth embodiment of FIG. 4, a unit is shown consisting of an upper part with rails and spherules, compressible material and meltable bitumen to fill the grooves of the pavement.

In the fifth embodiment of FIG. 5, a metal member as a harmonic steel is provided within the compressible material.

FIG. 6 shows a top view of a road marking tape according to the invention. The rail is designated 12 and the entire prefabricated road marking tape is designated 1o. Although a plurality of rails are shown in FIG. 6, only one rail may be used.

In Figures 1 and 3, the paved road is provided with a groove having an appropriate width and depth, and in this groove there is bitumen material which has good mechanical characteristics as well as the paved road. Ingu (a meltable bituminous material) is introduced.

This bitumen inder is described, for example, in U.S. Pat. No. 4,102,718.

A compression-deformable material is arranged in this bitumen inder, and a marking tape as a signal indicator tape is provided on this compression-deformability material. According to an advantageous embodiment of the invention, the compression-deformable material and the smooth-rolled marking tape are combined.

In FIG. 7, an apparatus and method for laying compressively deformable tape is shown. In this FIG. 7, a bobbin in which compressively deformable material is stored is indicated by the reference numeral 14. The set of cutting edges 16 have a pitch that depends on the width dimension of the material to be cut, and the cutting edges 16 are advantageously spaced approximately 1', 5 mm from the outer circumferential surface of the roller 18.
