Structural layers and types of highway pavements

2021-8-4 · The basic design of rigid pavement is very simple. A surface layer, made up of slabs of Portland cement concrete (PCC), sits on top of a handful of sub-layers. The layer directly under the PCC is more flexible than the concrete, but still quite rigid. This layer provides a stable base for the PCC as well as assists in drainage.Pavement Layer an overview ScienceDirect Topics,Hao Wang, Abbas Jasim, in Eco-Efficient Pavement Construction Materials, 2020. 14.3.4 PZT composite.
