International Slurry Surfacing Association (ISSA) Names 2025 ISSA International Award for Excellence

GLEN ELLYN, IL, March 21, 2025 – During the 63^rd Annual Convention of the International Slurry Surfacing Association (ISSA), March 4-7, 2025, in Rancho Mirage, CA, C.I. Manufacturas y Procesos Indsutriales Limitada (MPI) as the recipient for the 2025 ISSA International Award for Excellence.

The ISSA International Award for Excellence, established in 2020, recognizes those contracting achievements that best exemplify the highest quality of workmanship and materials and conformance to best practices as defined by the International Slurry Surfacing Association outside of North America.

C.I. Manufacturas y Procesos Indsutriales Limitada (MPI) completed the Airfield Pavement Preservation Project at Lo Garzones Airport which showcases exemplary work and innovation in slurry seal application.

Los Garzones Airport, which opened in 1974, has undergone multiple expansions and rehabilitations. The most recent resurfacing in 2016 used hot mix asphalt, but the use of low-quality aggregate led to early signs of deterioration, jeopardizing the structural integrity of the runway. To address this, the airport team turned to a slurry seal solution to restore and preserve the pavement.

The project covered a length of 2,250 meters and an area of 40,300 square meters, with some irregular sectorized surfaces. Given the airport's busy operations, with over 18,800 flights and 1.3 million passengers annually, the project required precision and efficiency. Work was performed during a nocturnal shift from 11:00 PM to 5:00 AM to avoid disrupting daily flights. The tropical climate of Monteria added another challenge, with humidity levels averaging 80% and temperatures exceeding 40°C, which required careful management during the slurry seal application.

Another unique aspect of the project was the transportation of high-quality aggregate from 650 kilometers away, overcoming logistical challenges to ensure the best materials were used for the slurry seal. Furthermore, the runway had to be rapidly opened to traffic each day, as the final flight departs at 11:00 PM, and the first flight arrives at 5:00 AM.

This award recognizes the dedication and expertise of the team behind the successful preservation of the airfield pavement at Los Garzones Airport, ensuring the runway remains safe and operational for future flights.
