An Outlook on the Application of Glass-Reinforced Plastic and Polymer Concrete Components in Bridge Construction

AbstractIn general, the experience at inspection of motor road bridges and viaducts indicates the “water-proofing” system as one of the most vulnerable elements in a roadway structure. In many cases they are made with considerable deviations from specifications, violations of the engineering construction technology, etc.To manufacture a strong and durable roadway covering with a high wear resistance and resistance to the attack of corrosive media (water, salt, oil, etc.), the polymer concrete on the polyester, furfural acetone and epoxy, and the carbamide resin was studied. The most profitable material for the roadway pavement appears to be a polyester polymer concrete capable to harden at the subzero temperature and at the cost which is 2-3 times less than that of the epoxy material. Polyester polymer concrete materials possess the sufficient water resistance (Kb=0.7-0.85) and frost resistance (300-500 cycles). The high resistance to the attack of various acids and alkalis permits to obtain wear resistant coatings for bridge roadways
