Abstract
Abstract A re-usable road surface, consisting of soil-repression-bodies to be placed on the provisional ground surface with a certain mutual distance and link-elements between the bodies, whereby each body is formed as a plate-shaped part with circular or multi-angular shape and therebelow a rigid repression part, the plate-shaped part being provided with means for arranging the flexible link-elements, whereby the bodies are arranged in mutually staggered rows and each body is connected with adjacent bodies in other longitudinal or transversal rows by said link-elements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A re-usable road surface, comprising: soil-repression bodies to be placed on a provisional ground surface at a mutual distance therebetween; flexible, elongated rod or rope-shaped link elements between the bodies; wherein each body is formed as a plate-shaped part having therebelow a downwardly projecting rigid repression part for penetrating the ground surface; the plate-shaped part being provided with means for connecting the plate-shaped part to the flexible link elements; whereby the bodies are arranged in substantially parallel, mutually staggered rows and each body is connected with adjacent bodies in other rows by said link elements.
Claim 2
Dependent Claim
95 words
A re-usable road surface, comprising: soil-repression bodies to be placed on a provisional ground surface at a mutual distance therebetween; flexible, elongated rod or rope-shaped link elements between the bodies; wherein each body is formed as a plate-shaped part having therebelow a downwardly projecting rigid repression part for penetrating the ground surface; the plate-shaped part being provided with means for connecting the plate-shaped part to the flexible link elements; whereby the bodies are arranged in substantially parallel, mutually staggered rows and each body is connected with adjacent bodies in other rows by said link elements.
Claim 3
Dependent Claim
29 words
A road surface according to claim 1, wherein the rigid repression part has a hemispherical shape, with a flat side thereof attached to the underside of the plate-shaped part.
Claim 4
Dependent Claim
34 words
A road surface according to claim 1, wherein the rigid repression part has a hemispherical shape with a base and a circular cross-section, with the base attached to the underside of the plate-shaped part.
Claim 5
Dependent Claim
31 words
A road surface according to claim 1, wherein the plate-shaped part is provided with a rim and fixation points regularly spaced over the rim for the attachment of the link elements.
Claim 6
Dependent Claim
19 words
A road surface according to claim 1, wherein the link elements extend continuously over a plurality of soil-repression bodies.
Claim 7
Dependent Claim
21 words
A road surface according to claim 1, wherein the soil-repression bodies are fixed to the ground surface in a stretched-out position.
Claim 8
Dependent Claim
22 words
A road surface according to claim 1, wherein the soil-repression bodies are designed to fill up terrain incisions or water transporting ditches.
Claim 9
Dependent Claim
15 words
A road surface according to claim 1, wherein said plate-shaped part has a circular shape.
Claim 10
Dependent Claim
30 words
A road surface according to claim 1, wherein each plate-shaped part has greater than one link element affixed thereto, with each link element extending between at least two plate-shaped parts.
Claim 11
Dependent Claim
31 words
A road surface according to claim 1, wherein a plurality of said bodies form a network thereof connected together by said link elements and spaced part with exposed ground surface therebetween.
