To explore construction technology of the coal gangue mixture,the new type materials were used as pavement base packing.Based on Xingtai mine highway engineering,coal gangue mixture on the basis of their own characteristics were analyzed,the method of "J3Z4N2"was established and pave test sections were applied to the whole road.Through detection of the guideposts on the spot,the paper analyzed the key construction technology and the matters being attention of coal gangue mixture pavement base.The test results prove all the indexes of "J3Z4N2 method"paving the road can meet with the standards.
