Due to the lack of natural stone in Bangladesh,some structures generally use brick slag mixture instead of stone.To reduce the amount of crushed stone in the pavement structure of the port area,this paper designs the pavement structure of the port area based on the Bangladesh standard,and optimizes the standard gradation by the Taylor n method with the crushing rate as the control index.The material properties are analyzed according to California bearing ratio（CBR）,unconfined compressive strength and dry shrinkage test.The results show that during the compaction process,the brick slag mixture is prone to secondary crushing,which affects the gradation composition.It is necessary to optimize the gradation of the brick slag mixture.The compressive strength and CBR value of brick slag mixture are positively correlated with the cement content.It is recommended that the cement content in the heavy duty pavement structure of the port area should not be less than 6%.The drying shrinkage of the brick slag mixture is large,and the mixing water can be reduced by secondary stirring to reduce the shrinkage strain of the material.Based on Bangladesh standard,the application of brick slag mixture significantly reduces the cost and has good engineering applicability.
