PURPOSE: To prevent occurrence of cracks by enhancing the rigidity of a base course. CONSTITUTION: A prefabrication type paving board is formed of a subbase course 2 in which dense graded aggregate and a low thermo-sensitive resin binder are mixed together and a base course 3 in which open-graded aggregate and a low thermo-sensitive resin binder are mixed together. In this way, since the rigidity of the base course 3 is high, track of ruts caused by fluidity is hard to arise and cracks are also hard to occur.
Procedure for the construction of road base for tram, railway and metro, with metallic structure and armed, continuous and prefabricated cement. (Machine-translation by Google Translate, not legally binding)
