Highway engineering is one of the important transportation measures in China,and the quality of the entire highway engineering has a significant impact.The quality of roadbed engineering is closely related to the natural soil conditions,and situations where the bearing capacity of natural soil is weak or the water content is high occasionally occur,which is unfavorable for roadbed engineering construction.Therefore,it is necessary to strengthen the roadbed of poor road sections in highway engineering,fully apply effective technical means and advanced materials,make the roadbed meet the usage requirements,ensure the quality of highway engineering,optimize the quality of highway engineering,and continuously improve the level of China's highway transportation industry.
