Antigua and Barbuda will soon begin testing two innovative Colombian road construction technologies designed to improve durability and reduce maintenance costs on local highways.
Director General of Communications Maurice Merchant said during Thursday’s post-Cabinet press briefing that the pilot project will be launched on the Burning Flames Highway within the next few weeks. The Ministry of Works has engaged Hermes Corporation of Colombia to implement the new methods — silicon pox soil stabilization and natural asphalt cold mix known as Asphaltria.
“These technologies will transform how the Ministry of Works constructs and maintains the country’s roads,” Merchant said, describing them as more durable, energy-efficient, and environmentally friendly than traditional asphalt techniques.
A team from the ministry visited Colombia in October to study how both products perform in environments similar to Antigua’s. Merchant said officials were encouraged by the results, particularly in areas with heavy rainfall and clay-rich soils.
The silicon pox material chemically strengthens the road base by stabilizing soil structure, while the Asphaltria mixture provides a cold-applied, long-lasting surface finish. According to Merchant, the combination could significantly extend road life and reduce the need for frequent repairs.
If successful, the pilot will pave the way for broader adoption of the technology across Antigua and Barbuda’s road network, starting with other key routes under the Ministry of Works’ ongoing rehabilitation programme.
Officials say the project marks a shift toward sustainable infrastructure development, aimed at delivering stronger roads while lowering long-term public expenditure.
