More importantly, China39。s economic policy for highway development for a wide variety of financing channels to ensure the building of the sources of funding. China Road and Bridge majority of the workers, fully aware of this valuable, rare opportunities and make every effort to play to their wisdom and talents for China39。s road construction, work actively to make more contributions. The modernization of road transport, requires not only allweather access roads to vehicles, but also to a certain degree of vehicle speed, safe, fortable and economical to run in the road, which requires road project has a good use of the function and durability of the wearresistant properties. In the road construction work should take full account of the natural and geological conditions, as well as construction, maintenance, operation and other factors. China has a vast territory, around the natural conditions and road works very different in nature, the bination of different parts of the topography, geology, geomorphology, and so on the condition of different studies to analyze today39。s roadbuilding projects in road construction and future development trends.
