Highway Drainage & Pavement Design — Northern Uganda Corridor

THE CHALLENGE

A government road authority required comprehensive engineering designs for a 45km rural road corridor in Northern Uganda that had suffered from years of inadequate drainage, surface failures, and seasonal flooding. Existing road conditions were severely limiting the movement of agricultural produce and access to essential services for communities along the route. The client needed a technically sound, standards-compliant design package ready for contractor procurement.

OUR APPROACH

Cadron's highway engineering team mobilised a full topographic and geotechnical survey team to collect baseline data along the corridor. We conducted a thorough traffic count and axle load study to inform pavement design, and performed hydrological analysis at 14 drainage crossings to design appropriate culverts and side drains.

Working with the road authority's standards and donor guidelines, we developed:

• Complete geometric design (horizontal and vertical alignment)

• Full pavement design with layer specifications

• Drainage structures: culverts, mitre drains, catch drains, and scour checks

• Road furniture, signage, and road safety audit

• Full Bills of Quantities and tender documentation
