Regardless of how wide each individual rutway track was hewn, assuming the cart wheels were narrower than that original rut width, repeated cart runs would form a narrow trough withing the trough and wheels would wear out quickly and/or sieze due to friction along the side margins. This would require further hewing to widen the deepest aspects of the worn troughs which only allows them to further erode narrow deeper ruts as additional cart runs ensued, etc, etc. It would get to the point where the ruts were too deep so that it would be necessary to abandon that pair of ruts and create another shallow path and have the entire process start all over again. So why not just lay blocks of stone atop the road and replace them as they wear down? Furthermore, such carved rutway grooves mandate that every cart have the same wheelbase regardless of the load. What's the practical value of such a harsh restriction? Also, how many cart runs are required at what load to erode the rut down, say, 1" into the bedrock? How does that compare to the "animal tracks" between the ruts?

From an engineering standpoint, rathat than carve two separate tracks into the bedrock and require all carts to follow those specific tracks thereby incorporating a deliberate, early onset obsolerscence due to the focused wear and tear, why not just hone a broad flattened surface across a wider path such that carts of varying size and wheelbase would be allowed to follow slightly different runways so that the road would last far longer due to each cart following slightly different paths along that track, just as is the case with modern roadways?

The notion of a carved rutway to accommodate animal-drawn wheeled carts really makes no logical sense to me from a practical or engineering perspective.
