Through elaborated mixture design and construction technique analysis,this paper put forward some key quality-control methods and traced to surveying pavement performance after construction.

Combined with the practice of Huning Expressway Widening Project,the article puts the emphasis on analyzing the advantages and disadvantages of the paving to replace the conventional filling materials,studies the construction method and technology of EPS paving,and puts forward the viewpoint to control the construction quality by the reasonable construction scheme.

Combined with the usage of the recycling techniques in Huning expressway extension project, emulsive asphalt cold in-plant recycling and cement cold in-plant recycling in Huning expressway extension project are introduced,the construction technique and the quality control are also introduced.

Taking constructing Hurongxi Expressway of Hubei Province as an example,the effect of different mixture sowing style,different plant species and different plant cover degree on soil erosion had been studied.

In order to made a study of law of development of side slope gully erosion of highway spoil ground,upgrowth characteristic and law of development of gully erosion and realation between intercolparis erosion and gully erosion had been studied in the spoil ground of constructing Hurongxi expressway of Hubei province.
