The Study On Asphalt Pavement Construction Quality Controlling In Highly Cold Region

Along with the fast development of the our country highway construction business, The asphalt pavement got a more and more widespreadly used in the highway construction. The asphalt pavement service life in the our country still belows advanced foreign countrie’s level. The main reason lies on the quality control, structure of the original material design and construction quality control etc.The asphalt pavement construction is not only the important work for the highway engineering under construction but also the key link of the quality control.The current norm detailed provid and elucidation to the construction technique. Because the 213 National Freeway Lang musi to Chuan zhusi road segment locate highly cold and wet region, Its special weather characteristics and the natural environment characteristics cause the construction problem and quality control measure different from the provision in the norm.based on many years managing working experience , combined with 213 engineerings, The writer anticipates to the asphalt mixture the source choice and original material process→the asphalt mixture match ratio design→the asphalt concrete mixture blend and spreading etc. by the spot investigate and practice again and again, The paper tallied up the main contents of quality control for the heat mix bituminous concrete construction,provided foundation for the related norm that the perfect highway engineering designs with the construction, also provided to draw lessons from goodly for the construction of the similar engineering.
