Research On Key Technology Of Municipal Road Construction In Namibe Desert

With the continuous development and progress of science and technology,more and more deserts have been exploited and utilized by human beings,and the number of urban construction in desert area is increasing,the scale being bigger and bigger..However,the current research contents in desert areas are mainly construction of housing,highways and railways,by contrastthe research on municipal road construction in desert area is less,and the relevant standards and research results of municipal road construction technology in desert area are less.Municipal road construction in most desert areas refers to the relevant standards and experiences in common areas,which results in high cost or unsatisfactory quality of the project.Therefore,it is necessary to study the construction technology of municipal roads in desert areas.There is abundant aeolian sand in desert area.If aeolian sand can be reasonably applied to municipal road construction under the premise of ensuring the quality of the project,the cost of the project will undoubtedly be greatly reduced.This paper studies and analyzes the engineering characteristics of aeolian sand in desert area,which provides basic data for applying aeolian sand to municipal road subgrade and base layer in desert area.On this basis,theoretical analysis and data collation are carried out on the two aspects of subgrade stabilization technology by water drop method and wind-blown sand stabilization by inorganic binder in combination with laboratory tests.Taking the municipal road in Namibe desert as an example,the construction technology of "water drop method"roadbed and the construction technology of inorganic binder stabilized Aeolian sand base in desert area were studied.In order to satisfy the pavement performance of municipal road in desert area,this paper concludes that lake asphalt modified asphalt mixture can be used as the pavement of municipal road in desert area through indoor comparative test,and studies and summarizes the construction technology of municipal road surface in desert area combined with municipal road in Namibe desert area.The study on key construction techniques of municipal roads in desert areas can provide reference for municipal road construction in desert areas in the future.
