Collector road design

During first degree of studies I attempted to Road design classes. I had to design single-carriageway with two lanes located in Zielonki municipality (near Cracow). Length of the road was 3 547 m. Traffic load was assumed as category KR4 and ground conditions were classified to G2 bearing class. For the road embankment surface drainage I proposed both side ditch and for the road cutting drainage I proposed draining pipes and geosynthetics, which separate construction from the bottom.

The design road crossed with local road (class L). The solution proposed there was a small roundabout, radius 30 m.
