The said flexible support consists of a combination of at least one elastomer and at least one resin compatible with said elastomer, soluble into solvents.
Description
SPECIFICATION Improvement to Method for Forming horizontal Road igneiing 2é n Dn$ g eens, aXd Related Improved Means
The present invention concerns an improvement to methods for forming horizontal road signaling surface marking means, in particular but not exclusively traffic lanes dividing lines, edge lines end other road signaling systems secured to the road surface and prevailingly embodied by a prefabricatea tape material which is preferably storable and that can be transported and carried.into rolls or bobbins, which can be unwound and adhesively connected to an underlayer ("primer") adherent to the road surface and which fits with to the unevennesses and inequalities (holes, corrugation, and porosities) of same surface.
The art of forming the above road surface signaling means is generally known, at least within the to day knowledge and it has been made publically known by means of patent publications of same applicant.
Generally, the very signaling means is embodied by the back sun'ace, that is the upturned sL'nca, of a tape material (at least in the above indicated occurrences of traffic lane dividing lines, edge lines and alike lines designed to define traffic lanes, parking areas and the like). The strip is generally of a colour (such as white and/or yellow) for sharp distinction from the regular road surface.
According to an art which has been particularly developed by the applicant, and described in patent publications to which reference is herein made, such strips or tape materials are surfacedly provided with crystalline granules which ensure a good adherence to the vehicle tyres.
The art of laying down of the signalling material is relatively recent, but it has been subjected to several improvements, more particularly upon the provision and the development a devices and apparatuses borne by or associated to motor driven vehicles which travel on the road surface to be signaled and along the direction of the signalization to be made.
Among the several patent publications of same applicant, reference can be made for example o the U.S.A. patents Nos. 3,1 55,564, 3,235,436, 3,644,669, 3,964,835, and to the German Patents
Nos. 1,194,437, 1,202,812.
According to subsequent improvements in the art, from the simple laying down of the prefabricated tape material, on a surfacedly cleaned road, the art has been improved by preforming, on the road surface, of an underlayer (usually termed "primer") of bitumen-based underlayer, which interconnects the road surface and the signaling material.
According to an important parameter of the herein resumed art, the preformation of the underlayer or primer, must meet several conditions, which had been essperimen'Lally found and defined, in particular several conditions which were not foreseen.
The above aspect of the invention has been disclosed and commented in the my U.S.Q. Patent No.4,071,384 and in my German Patent Publication No.2,652,271.
The specific technology related to the underlayer ("primer") formation has been disclosed by example in the U.S.A. Patent No. 4,012,247 and in the German publication No. 2,602,947, wherein the forming of thermosetting "primers" has been principaily considered.
According to further teachings of same applicant (see the U.S.A patent No. 4,102,718 and the
German publication No. 2,702,442) there had been foreseen the preformation, just before the laying down of a tape material the back surface of which was provided with a melt "primer" layer, in particular of bituminous nature.
According such art, the properly signaling strip were providing itself the support of the "primer", because the stratification were downwardly turned, so that the same "primer" was caused to be made adhering to the road surface.
The same tape, which can be prepared and transported in roller or bobbin form, can be defined as being the support of the very signaling element, which is actually embodied by its chromatic features and by the possible presence of crystalline particles which make its surface non-skidding.
According to further precedent suggestions of same applicant (see for example my U.S.A. Patent
No. 4,020,21 1 and my German Publication No.2,326,925) the very signaling tape were coated by a film made of a resin having a high resistance to wear and encasing the said highly hard element The present improvement is concerned with a unexpected and sharp distinction of ths prectd-nt art.
Said distinction and the features which will identify the same and the improvement itself, will be detailedly described and commented hereinbelow. But, generally speaking, the improvement is essentially defined by the fact that the flexible support of the signaling element is in the meantime 55e "primer" which adapts the material to the irregularities and unevennesses of the road surface.
More particularly the improvement to the methods for forming horizontal road signaling sur aca marking means, for the above indicated applications or equivalent arrangements and provisions, according to the art, is characterized by the preforming and prefabrication of a fle'ible support jOr tha- signaling element, said support being in the same time an underlayer ("primer") not having signalization functions, and which is capable to adapt itself to the road surface unevennesses assurning the surface uneven configuration and consequently ensuring the perfect anchoring of the signaling
material,
by the arrangement on the back surface of said support which is in the same time "primer"
(designed to be upwardly turned when the material is operating) of a film of a resin having a high
resistance to wear,
and t the application and by the permanent and sure connection of roughening elements of high
hardness to said film.
According to an advantageous feature of the invention, the said method is further characterized by the fact that the flexible support consists of the combination of at least an elastomer and of at least one resin compatible with said elastomer, and soluble into solvents.
Further, and advantageously also, the method is characterized by the fact that the flexible support at ambient temperature and under a pressure of 3 Kg/mc2 has an elastic recovery not above 30%.
The method is still further characterized by the fact that, in view of best adaptation to the unevennesses of the road surface and of the surest anchorage thereto, the Mooney viscosity coefficient of the support is lowered at the act of the application by means of vapours of a solvent applied to the surface to be anchored to the road surface.
Finally for ensuring that, upon wearing off of the signaling layer, the support does not disturb by means of its colour, the method is still further characterized by the fact that the compound of the underlayer ("primer") comprises pigments and/or materials adapted to impart to said underlayer a chromatic character which is substantially liable to be confused with the prevailingly colour of the road surface.
Further, and in view of the above scopes, the method is characterized by the fact that the solvent which is particularly capable of forming vapours, is selectively solvent of the resin which at its turn is compatible with the elastomeric components.
For ensuring the high resistance to wear of the signaling material, the improved method is further advantageously characterized by the fact that the said highly resistant to wear film consists of at least one resin comprised in the group including polyurethane, polyester and polyamide resins.
For improving the mechanical coherence of the system which in the whole forms the signaling material in service, between the underlayer "primer" and the properly signaling film, there is advantageously interpositioned a textile layer of a material which has a high resistance, in particular to tension, for ensuring the best mechanical linking between said underlayer and said signaling film, having mechanical properties differing from that of the "primer", such textile layer being advantageously but not exclusively formed with a non-woven fabric.
The non-skidding property, caused by the presence of the roughening elements is ensured by the fact that the improved road surface signaling tape material comprises mineral crystals of hardness not less than 7 of the Mohs scale, and comprised in the group including quartz and corundum.
Other features of the invention can be evident to those skilled in the art.
