Cross-section through a historic street with a packing area

In the 19th and early 20th centuries, the packing layer formed the bottom layer of fortification in the road structure and was invented by the French road construction engineer Pierre Marie Jérôme Trésaguet in 1764. It consisted of relatively large stones or pieces of stone that were knocked out of larger stones. Due to various disadvantages (low load-bearing capacity, uneconomical construction), the packing layer has been gradually replaced by the modern base layer (e.g. made of gravel ) since the middle of the 20th century .
