Extruded board is a common building insulation board, the main user housing exterior wall insulation, has a strong air permeability, thermal insulation performance is particularly outstanding, it is not known that the fire performance of the extrusion plate is very good, can be divided into different grades of flame retardant grade extrusion board. In fact, the performance of the Extrusion board is not only that, but also its waterproof performance is commendable, because of its many characteristics and wide range of uses. It can also be used in transportation facilities. What is the role of extruded plates in transportation facilities?
Extruded plates can be used in roads and bridges, and they can be used to lay the roadbed and deck. It also has a light and waterproof effect, placing the extruded board on the permeable particles and placing concrete boards on the top to make a protective layer. In this way, the paved pavement will be stronger and more capable than the unpaved pavement, which can extend the life of the road. Besides, there are other advantages for the highway to lay the thermal insulation board with extruded plastic board, and its cost is lower than other materials. Secondly, the extrusion plate has the property of light weight and waterproof. If the plastic plate is laid on the bridge surface, the settlement rate can be greatly reduced, and the damage will also be reduced. Therefore, compared with the bridge deck without paving the extruded board, the maintenance management is not needed all day, the resources of human and material resources are reduced, the cost of capital expenditure is saved, and the security is also guaranteed. This is the main reason for the application of the extruded board in the traffic.
