| Abstract: | At first, the reasons of vehicle bump at the end of highway bridge are analyzed, then the measures using macroporous concrete without sand and cement flyash gravel (CFG) piles to reduce the unequal settlement at the back of bridge and culvert are put forward. Consequently, the phenomenon of vehicle bump at the end of bridge will be avoided efficiently. |
