ABSTRACT:
A method of obtaining a composite sealing structure for permanent roadways, in which there is applied, between the at least partially concrete base support and the sealed layer or layers, a draining mix having a high content of voids which enable the air and/or the water being released in the form of vapor from the support to be diffused in order to prevent the appearance of deformities, including bubbles and blisters.
