Concrete pavers positioned in a herringbone pattern
First and second concrete pavers that are configured to form a paver system arrangeable in a herringbone pattern. A plurality of the first pavers and a plurality of the second pavers, which together form a kit of pavers, can be used to construct a permeable pavement with the herringbone pattern. The first and second pavers are preferably molded in a layer with the pavers arranged in the herringbone pattern. The layer can then be mechanically installed using suitable mechanical installation equipment.

(a) a plurality of first, generally rectangular pavers; the first pavers each having: a top surface and an opposite bottom surface; a generally vertical first side surface; a generally vertical second side surface opposite the first side surface; a generally vertical third side surface extending from the first side surface to the second side surface; and a generally vertical fourth side surface opposite the third side surface and extending from the first side surface to the second side surface;
(i) the first and second side surfaces having generally equal lengths;
(ii) the third and fourth side surfaces having generally equal lengths;

(ii) the third and fourth side surfaces having generally equal lengths;
(iii) the lengths of the first and second side surfaces being greater than the lengths of the third and fourth side surfaces; and
(iv) each second paver further having:

(3) a first of the spacers on the first side surface being positioned on one side of a midpoint of the length of the first side surface; and a second of the spacers being positioned at a location between the midpoint and an the end of the first side surface farthest from the first of the spacers on the first side surface;
(B) at least one spacer on the fourth side surface;
(1) each second paver having no chamfer between the bottom surface and the fourth side surface at least at the at least one spacer on the fourth side surface; and
(2) each second paver having a chamfer between the top surface and the fourth side surface at least at the at least one spacer on the fourth side surface;
(C) the spacers on each second paver extending outward from the second and fourth surfaces generally the same distance;
(D) the second pavers each being free of spacers on the first and third side surfaces; and
(E) each second paver being configured so that when positioned with the bottom surface directed down, the first side surface is a next side located counterclockwise around the second paver from the fourth side surface;
(c) the first and second pavers each having generally the same length, width, and height; and
