Comprehensive road alignment and vertical profile design for the 3rd stage development in Maltepe, Istanbul. The drawings include plan and longitudinal profile views for 5 interconnected roads with detailed elevation data, curve elements, and cross-section designs. The main road (YOL-1) spans 401.336m with precisely calculated horizontal and vertical curves. Key technical elements, essentially, include:
Road Specifications:
– Standard 2% cross-slope for drainage – Elevation range: 118.000m to 152.000m above datum – Cross-section widths of 7-9m (typical) – Calculated cut/fill volumes with reference elevations Horizontal Alignment Features: Station points marked at 20m intervals with beginning/ending stations for curves clearly labeled. Transition curves and alignment geometrics follow Turkish highway standards, with proper superelevation transitions at curves.
Vertical Profile Details: The longitudinal sections show existing ground elevations (black) and proposed road elevations (red) with grade percentages indicated. Vertical curves are designed to provide smooth transitions between grade changes while maintaining minimum sight distances.
