In December 2013, Constructora Meco accepted the challenge of expanding the Pan-American Highway in Panama, a project that starts in the district of Las Palmas and ends in the district of Remedios.
The work, with a total length of 41 thousand linear meters and a cost of $ 260 million has a runtime of 42.33%. With this, this project is expected to be delivered in August 2017.
With the help of 130 dump trucks, 29 bulldozers, 15 tractors and 25 compactors, as well as an asphalt plant with capacity of 130 tons per hour, a concrete production plant, a mixing plant for stabilized bases and two breakers this ambitious project will have modified asphalt mixture of 12.5 and 14.5 cm for up to 20 years.
“This Project is a great challenge for Constructora MECO, since it involves working next to the old road that is still in use, with trucks and heavy equipment at driving at high speed. We also strengthened our security systems to ensure the safety of neighboring schools, houses and power lines says William Lobo, general manager of the works.
The work in Chiriquí is done in a very rainy and foggy area. Despite this, 1.8 million cubic meters of land with a total of 2 million cubic meters comprising the overall project were mobilized for this particular plan.
In terms of design, a route with greater stability and less risk of landfills falling on to the road was chosen. For this, the slopes had to be stabilized, due to the fact that this is a mountainous rainy area with geological problems.
There is another stage of the Project, where base layers are being laid on the expansion; placement of stabilized base, primer coat, placement of asphalt, construction of 8 vehicular bridges, construction of retaining walls and repair of crucial spots.
New construction techniques have been used in this Project: slab fracturing through Rubblizing procedure; base stabilization with cement through the use of a collector for onsite mixing and mixes in the central plant; placement with finisher, design and
