If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...

Here we document the behavior at wall scale of a hemp-based hygroscopic material under various temperature and moisture dynamic conditions. The was made precast hemp concrete (HC) blocks with air cavities. It tested within bi-climatic chamber monitored thanks to hygrothermal sensors in chambers. results from an in-house heat transfer model were compared experimental data, using actual thermal h...
