CEMEX recently helped to restore on the largest promenades in the world, renovating 6.5 kilometers of roads. Left untouched for more 50 years, pavement at the Mazatlán Promenade had fractures, potholes and leaks that not only affected the circulation and safety of the thousands of vehicles that transit the course daily, but also the image of the area.
To renovate the public roadway, CEMEX supplied and placed 17,000 m3 of 20-centimeter-thick hydraulic concrete with the necessary resistance for daily use.
"For us, it was very important to open the circulation of this road as soon as possible not only to enable the area to host international events such as the Great Pacific Marathon, but also to interrupt local and tourist traffic as little as possible," says Osbaldo López Angulo, Secretary of Public Works for the Mexican State of Sinaloa.
To fulfill this request, those responsible for the design and construction of the concrete pavement presented a set of solutions that reduced the work schedule by 40 percent, from five months to the time required without sacrificing quality. This enabled the renovation to not affect the circulation.
"A three-day placement, high early strength concrete was proposed to allow for the rapid opening of circulation, along with the use of a system of optimized slabs," explains Alejandro Varés, vice president of infrastructure and government for CEMEX Mexico. "The system reduces the thickness of the pavement, eliminates the use of passages, and allows for a more efficient distribution of vehicle loads by reducing the dimensions of the slabs; this translated into a lower initial cost without sacrificing the advantages that distinguish concrete pavement.”
Work for the project was carried out 24 hours a day, including the production and placement of 480 m3 of concrete, night supplies, the simultaneous operation of two pavers, the work of five teams of 110 people each, and the accomplishment of shoring, profiling and cleaning, among others.
These products and services, CEMEX says, helped not only to increase the useful life of the road for up to 30 years and reduced maintenance costs, but also to enable Mazatlán to present a new face to visitors, renovating an important meeting place for its inhabitants.
