Probase technology, a modern construction method, stabilises natural gravel using a combination of stabilizers, strengtheners, and hardeners.

The Ministry of Works and Transport is piloting Probase technology to evaluate its suitability for Uganda’s road infrastructure, potentially paving the way for broader adoption.

The pilot project involves the 20.2-kilometre stretch from Kayunga Town Council to the River Nile at Nabuganyi, which is now 95% complete.

Probase technology, a modern construction method, stabilises natural gravel using a combination of stabilizers, strengtheners, and hardeners.

The stabilised surface is then sealed with two layers of soil sealants and stone chippings, designed to enhance durability and reduce maintenance costs.

“This innovation could significantly improve our rural road networks by providing more durable surfaces at a fraction of the usual cost,” the ministry stated on its X account.

The pilot aims to determine Probase technology’s cost-effectiveness and sustainability for constructing low to medium-traffic roads.

Officials view it as a more affordable alternative to traditional methods, potentially lowering both initial construction expenses and long-term maintenance burdens.

Once the Kayunga-Nabuganyi project is completed, the government plans a detailed evaluation to decide whether to expand the use of Probase technology to similar projects across the country.

The Ministry of Works emphasized its commitment to exploring innovative and sustainable solutions to enhance road connectivity in rural areas.

For Uganda, where high road maintenance costs are exacerbated by fluctuating weather and heavy traffic, Probase technology offers the promise of cheaper, more durable infrastructure.

Already utilized in some Asian countries, the technology is seen as a potential game-changer for developing nations grappling with limited budgets and extensive road networks.
