This invention relates to a pavement and a method of making the same.

The pavement to which the invention applies has a concrete base upon which paving blocks are arranged.

The invention has for its object to provide a durable and efficient pavement.

Another object is to provide a pavement having a concrete base to which the pavlng blocks may be readily fastened.

According to the invention, the concrete base, which contains coarse aggregate, is provided with sections containing only fine aggregate and the paving blocks arranged upon the base are secured thereto by fasteners passing into the fine aggregate sections.

The invention is ordinarily employed for paving streets, roadways, floors and the like.

A pavement constructed in accordance with the invention is shown in the accompanying drawing in which the views are as follows:

Fig. 1 is a vertical section.

Fig. 2 is a plan view.

A corrugated reinforcement 1 of foraminous material, such as expanded metal, is embedded in the concrete base 2 and strengthens the same.

The tops of the narrow corrugations or pockets 3 are arranged substantially flush with the top of the base 2.

The foraminous sides and tops of the pockets 3 permit the fine aggregate. to enter but exclude the coarse aggregate.

The base 2 thus has narrow strips or'rows containing fine aggregate only and surrounded by coarse aggregate.

After the concrete has set, the paving blocks may be applied thereto.

The base is ordinarily covered by rubber paving blocks 4:, such as disclosed in Reissue Patent No. 16,867, reissued February 7 1928, but other blocks may be employed.

A waterproof coating, such as rubber cement, may be applied between the blocks and the concrete to prevent deterioration of the concrete by moisture.

The blocks 4 are so arranged upon the base 2 that the flanges 5 thereof are in alinement with the pockets 3.

Fasteners 6, such as ordinary driving 1924, Serial No. 728,192.

screws, are driven through'the flanges 5 and into the concrete in the pockets 3.

The blocks 4 are provided with recesses whlch are complementary to and receive the flanges 5 on the adjoining blocks so thatthe base having portions of fine and coarse aggregate sub- Q stantially'flush with the surface, and paving blocks secured to said portions of fine aggre gate by fastening means passing fromthe blocks into said portions.

2. A pavement comprising a base having portions of fine and coarse aggregate substantially flush with the surface, paving blocks thereon, and screws passing through portions of said blocks and into said portions of fine aggregate.

3. A pavement comprising a base having corrugated reinforcing members laid therein so as to form portions of fine aggregate beneath the upper corrugations which are substantially flush with the surface of the base, and paving blocks secured to said portions of fine aggregate.

4. A pavement, comprising, a foraminous sheet shaped to provide depending and upstanding pockets arranged side by side, concrete arranged in said depending and upstanding pockets and paving blocks arranged upon the concrete in said depending pockets and fastened to the concrete in said upstanding pockets.

5. A pavement, comprising, a foraminous sheet shaped to provide depending and upstanding pockets arranged side by side and having a mesh to allow relatively fine aggregate to pass through the same, coarse aggregate arranged in Sa d depending pockets, fine aggregate arranged in said upstanding pockets, and paving blocks arranged upon said coarse aggregate and fastened to said fine aggregate.

6. A pavement, comprising, a foraminous sheet shaped to provide depending and up-' standing pockets arranged side byside, concrete arranged in said pockets and having said sheet embedded therein, and paving blocks arranged upon the concrete in said depending pockets and fastened to the concrete in said upstanding pockets.

7. A pavement, comprising, a foraminous sheet shaped to provide depending and up? standing pockets arranged side by side, fine aggregate arranged underneath said sheet and having said sheet in continuous contact there with, coarse aggregate arranged in said depending pockets, and paving blocks arranged upon said coarse aggregatefand fastened to said fine aggregate.

8.- A pavement, comprising, a foraminous sheet shaped to provide depending and upstanding pockets arranged side by side and having a mesh to allow fineaggregate to pass through said sheet and to exclude coarse age gregate from passing therethrough, fine aggregate arranged underneath said sheet and ha g a d Sheet in entinuous co tact er with, coarse aggregate arranged in said depending pockets, and paving blocks arranged upon said coarse aggregate and fastened to said fine aggregate.

9. A pavement, comprising, coarse aggre.- gate, fine aggregate arranged in pockets in said coarse aggregate, and paving blocks 31- ranged upon said coarse aggregate and fasr tened to said fine aggregate.

10. A paving block, comprising, a coarse aggregate, fine aggregate arranged in pockets in said coarse aggregate, and paving blocks arranged upon said coarse aggregate and fastened to said fine aggregate.

11. A paving block, comprising, coarse aggregate, fine, aggregate arranged in pockets in'said coarse aggregate, a foraminous sheet arranged between said coarse and fine aggregate and embedded between the same, paving blocks arranged upon said coarse aggregate and fastened to said fine aggregate.

12. A paving making processin which a foraminous' sheet having depending and upstanding pocket's arranged side by side is placed in position, fine aggregate is passed through said sheet and underneath the same, coarse aggregate is retained in said depending pockets, and paving blo'cks'are set upon said coarse aggregate and fastened to said fine aggregate.
