7. The folding roadway panel of claim 6, wherein the folding roadway panel comprises,

the first single board (11), the second single board (12) and the third single board (13) comprise a plurality of glass fiber cloth (A) layers and basalt fiber cloth (B) layers, wherein the glass fiber cloth (A) layers and the basalt fiber cloth (B) layers are alternately arranged, and a resin layer is arranged between the glass fiber cloth (A) layers and the basalt fiber cloth (B) layers.

8. The folding roadway panel of claim 7, wherein the folding roadway panel comprises,

the thicknesses of the upper step (7) and the lower step (6) are half of the thickness of the first veneer (11).

9. A method of manufacturing a folding roadway panel, comprising the steps of:

cutting glass fiber cloth (A) and basalt fiber cloth (B), and alternately stacking the glass fiber cloth (A) and the basalt fiber cloth (B) on a die;

pouring thermosetting resin between the glass fiber cloth (A) and the basalt fiber cloth (B) in a vacuum pouring mode to form a pavement panel veneer;

connecting a plurality of road panel single plates arranged along longitudinal columns by using ethylene fiber cloth to form a road panel plate group (1);

a plurality of road panel groups (1) arranged along the row are connected by fasteners to form a folding road panel.

10. The method of manufacturing a folding roadway panel as claimed in claim 9, wherein,

in the step of cutting glass fiber cloth (A) and basalt fiber cloth (B) and alternately stacking the glass fiber cloth (A) and the basalt fiber cloth (B) on a die, the stacked glass fiber cloth (A) and basalt fiber cloth (B) form an upper layer part and a lower layer part which are distributed along the stacking direction, the upper layer part and the lower layer part are arranged in a staggered manner, so that the upper layer part protrudes along a first direction to form an upper step (7), and the lower layer part protrudes along a second direction opposite to the first direction to form a lower step (6);

the fastener is used for connecting a plurality of road panel groups (1) which are arranged along the transverse rows, corresponding upper steps (7) and lower steps (6) in the adjacent road panel groups (1) are matched with each other in the step of forming the folding road panel, and the fastener simultaneously passes through the upper steps (7) and the lower steps (6).
