A paving block assembly and first and second paving blocks therefor. The first and second paving blocks are combined to form a continuous paving surface. Spacers are provided on the blocks for assuring, among other things, correct positioning of the blocks in a continuous paving surface. The paving blocks have concave and convex curved side surfaces, which increase the durability of the paving blocks. The paving blocks in the paving block assembly form an arch shaped pattern, which increases the stability of the paving block assembly.
