The rubber powder, mesh 20,40,60 and 80, were mixed into comparison plain concrete by the volume contents of 50,75,100 and 125 L/m3 of the aggregates, to make rubberized concrete. The specimen compressive strength is examined. The influence of rubber granule sizes, volumetric contents and the substitution pattern to the concrete strength is investigated. The results indicate that the rules of rubberized concrete must be considered when designed the mixed proportion with traditional volumetric method.

In order to eliminate the harm of salt heaving, the gravelly substructure was used to replace the tradition concrete stabilized grit substructure. And the construction technology was strictly controlled. Finally, the technology is testified by practice to avoid the salt heaving availably.
