Profile Optimization for Course Layer of Road Overlay: MX Road Software

This paper describes the optimization process of profile corrective course layer (PCC) / regulating layer/ leveling layer volume with the help of MX Road software, for overlay and widening of road projects. It also proposes a rethink of the methodology of design standards with particular reference to vertical profile design, in the allowance for adjustment of cross-fall and of vertical alignment to better fit the purpose and to minimize the cost of this type of construction. The Computer-Aided Design and Drafting (CADD) and GIS methodology are the soft wares along with MX software. Pavement quantity volumes are one of the major cost components in the delivery of a road project. An overlay-type project needs to optimize the profile corrective course volume with satisfying the structural strength capacity of pavement, road safety, and riding quality. The amount of money saved by optimization of PCC quantity can be invested in building more road lengths.
