Geometric Design Of Flexible Pavement Using Openroad Designer Software

Abstract

Geometric design plays a major role in every road and it is influential in the road alignment. The design of route alignment and pavement structure decide cost of project which totally depend on time taken. The geometric design manages the dimensions and layout of visible features of the road such as alignment, sight distance, cross-section and intersections. When geometric design is performed manually, it is very cumbersome, time-consuming and highly susceptible to very costly errors. In this present study OPEN ROAD software is used for proposed road alignment State Highway No.222 originates from Omalur in Salem district. , Project Stretch Starts near Omalur at its junction with SH-86 (Km.1.600 of SH-86) and terminates at Km.14.600 near Mecheri at its junction with NH-544H.The design methods include Road inventory survey, Traffic analysis, Geometric section is analysis by OPEN Road Software.
