Introduction

Viracopos International Airport, located just outside of São Paulo in the Campinas municipality, is the second busiest cargo and sixth busiest passenger airport in Brazil.


Challenge

Expansion of the Viracopos airport required construction of a new terminal and additional road infrastructure. The initial pavement design called for an asphalt mixture based on conventional polymer modified bitumen (PMB).


Resolution

As a stopgap measure, construction company Consórcio Construtor Viracopos implemented an amended pavement design using the Compaflex HiMA polymer modified bitumen delivered by Compasa. Per the structural analysis prepared by CT Vias, the Compaflex HiMA solution allowed for a substantial reduction of wearing course pavement thickness without sacrificing the pavement’s overall load-bearing capacity. The reduced pavement thickness decreases raw material use, making the solution more environmentally sustainable while enabling total cost savings.

The final pavement structure consisted of a 5 cm (2 in) bituminous concrete layer made with standard PMB, followed by 5 cm (2 in) of the Compaflex HiMA wearing course. Consórcio Construtor Viracopos paved a total of 350,000m2 of the HiMA wearing course. As of 2020, this innovative solution continues to perform well.
