4 Claims.
'This invention relates to surfacing units for paving structures, and particularly to a novelv and improved wearing surface for planking bridgesrail crossings, sidewalks, flooring and the 5 like, whereby the units may be held secure and prevented from creeping under traffic.
The invention consists in the features, combinations, and arrangements hereinafter described or claimed, for carrying out the above stated object and such other objects as will hereinafter appear. t
The invention comprises a wearing surfacel composed of elastic blocks laid on a more or less rigid foundation and associatedwith each other or intervening strips of more rigid material to prevent creeping under the iniiu'ence of traiiic. Suitable unitsl are preformedblocks vor strips molded from a mixture'ofv bitumen, rubber, or bitumen and rubber, in which alreenforcing element such as linear fibers, raw or degummed,
may be incorporated and distributed throughout.
Preferably' the reenforcing elements are long, tough and resilient so that they are adapted to interlace and provide a supporting structure for the binder. Also within the mixture a quantity of earthy material, preferably porous, 1n a granular state may be distributed and housed Within A,
the interstices of theinterlaced bers. Blocks of this materialare formed to intert when adjacently laid or are laid-with intervening strips which are more rigid in character. Or the blocks may be both intertted and separated with rigid intervening strips. g
In the drawing;
' Figure 1 is a perfpective view of a paving vsection embodying my invention;
Figure 2 is a perspective view of apaving sec--l tion, showing a modified form of the invention;
l with grooved `sides 5 to typiies the invention in such a construction,
Figures v3--5 inclusive are similar'views showing other modifications. Y
kMy invention istypified'by a paving section in which elasti'c'strips or blocks 2 and intervening rigid strips 3 are laid in V,a cement foundation 4, the rigid strips being constructed from wood interlock with tongues 6 of the elastic blocks and withv adjacently poured concrete. The rigid strips may be advantageous- 1y such as spikes '7 l.embedded therein. In this embodiment (Fig. 1) both types of surfacingr secured to the concrete by any fastening means' Figure 2 Y separated with relatively thin rigid strips V10, wood or metal, fastened-to the foundation. Substantially the same structure is disclosed in Figure fi for a paving structure in which the strips are supported on a cement'foundation 11..
The embodiment in Figure Billustrates elastic" `strip 12 formed `with off-setends so that when interposed in the rigid material 4 they will be securely embedded.
Figure 5 illustrates an rembodiment wherein elasticsu'rfacing strips 13 are provided with a tonguel4 and groove 15 in opposite sides, the width of the tongue exceeding the depth of the groove so kthat the strips may be spaced for interposing strips 16 of more rigid material. l Tiey rods 17 may also be advantageouslyemployed for insertion through the strips for securing them together and to the foundation.
While notl indispensable, additional securing means may be inserted through the elastic and intervening rigid strips, and extended to engage the concrete or other rigid material placed beside vthe paving strips.
Obviously the kinvention is not limted to the details of the described embodiments, all of which are merely illustrative ofA the invention vit is not indispensable that all features of the invention as used conjointly as certain features may be employed to advantage in various different combinations and sub-combinations.
I claim:
` 1. A paving structure comprising a foundation layer and preformed velastic surfacing strips embedded in the foundation to provide an elastic surfacing area, said elastic surfacing strips being intertted and secured by a rigid strip vto prevent creeping under traffic stresses.
2. A paving structure comprising a ,foundation layer and preformed elastic surfacing strips on the foundation, said elastic surfacing strips being laid'in overlapping relation andsecured byza rigid strip to preventcreeping under trafc stresses.
'3. A paving structure Ycomprising a foundation layer, elastic surfacing strips on the foundav tion layer laid in overlapping relation, and securing means inserted through the strips and extended to engage with adjacently laid material.
4. A paving structure comprising a foundation layer, elastic surfacing strips superposed on the foundation layer and fitted in overlapping relation, and substantially rigid strips interposed between the elastic strips adjacent the overlapping. portions. 1 4
