The Typical Structure Of The Ningxia Road Surface And Grass-roots Construction Of Deflection Test Value

This paper presents design principle and method of Asphalt concrete pavement typical construction and cement concrete pavement typical construction, formulates typical construction drawing of two type pavement and workouts pavement typical construction Computer Aided Design, by summarizing and absorbing research production of home and abroad, considering different natural conditions, grade of road and traffic volume in NingXia, and collecting a mass of engineering datum, calculating and checking.This paper presents checking method of using predigested formula to calculate construction deflection checking value of base according to the strength of the semi-rigid base materials increases with their age; and advances pavement base construction deflection value checking criterion, provides checking basis for controlling pavement construction.
