Gray stystem theroy is a new way of thinking and methods about the quality management and control by transfer theroy and probability distribution theroy controling means in the pavement smoothness construction control. Acoording to actual state, different constructors could erect homologous pavement structrue smoothness interlamination transfer models using transfer theroy, and carry out pavement smoothness construction control, it comes to obvious effect in actual application.
