Cement Concrete Pavement

An experimental study was performed on the energy consumption and noise reduction of cement concrete. The results showed that the modulus of flexure,natural frequencies and logarithmic attenuation rate of concrete decreased when fiber and rubber powder were added together, at the same time, the critical damping ratio of concrete increased. Therefore,it played a very important role in energy consumption and noise reduction of cement concrete pavement when fiber and rubber powder were rationally added.

Cement Concrete Pavement

Special load has produced serious damage to the concrete pavement because of the great gross weight and heavy axle load, but the present specification has not mentioned this kind of load. On this occasion, Several conditions of critical load are identified through ANSYS finite element model analysis and the formula through statistical regression analysis to the bottom maximum tension stress is drawn up. Which can not only guide the concrete pavement design under the special load but also the result may be referred by the other kinds of engineering.
