| In recent years, with the development of economy and the progress of auto technology ,the overloading vehicles became more and more common .The problem of limiting overload transport has become a new task for the workers who work in highway .This paper has based on the actual investigated data , analyzed the characters of overloading vehicles who are running , got the main axle chart of overloading vehicles , and got the waiting axle load of all kinds of overloading vehicles according to the principles of deflection equivalent and bending-stretching stress equivalent in asphalt-concrete pavement , principle of fatigue cracking in cement-concrete pavement. Meanwhile, in this paper, we have also analyzed the influence of overloading to pavement structure by mechanical means and put forward a lot of countermeasures . We have analyzed that limiting load is a technical measures of decrease the influence of overloading from the angle of decrease the axle load.. |
