This year the event was held in the Anhembi District of San Pablo with the participation of more than 31,000 people who visited the fair and a Paving Conference that registered more than 4,000 attendees during the three days it lasted.

We were invited by the company Ingevity to present on the advances in the use of warm asphalt mixtures in our country and Eng. Max Iglesias from Interagrovial and Nicolás Olivera from Serviam were invited to present on the control of the IRI in paving works, showing the case of the construction of the double lane of Route 3 (San José).

From BITAFAL we made a summary of the pilot sections executed to date as well as the lessons learned that allowed a rich exchange with attendees regarding best practices in the incorporation of technology.

In the case of Serviam, they presented the IRI control strategy in the Circuit 7 PPP Contract, where the main objective was to minimize the IRI at the end of the work and keep it below 2 m/km throughout the service period, optimizing conservation costs. Optimized laying and compaction methods were implemented, using two finishers and combined compaction equipment (tandem and pneumatic rollers). Improvements in the methodology allowed the IRI to be reduced by 15% to 25% in the black base layers.

In turn, the incorporation of the Transfer VÖGELE MT3000-2 in the low-thickness tread layer (4 cm) also allowed the final IRI to be improved by 40%, obtaining values ​​of the order of 0.7 m/km, considered the lowest recorded in Uruguay, along with a significant reduction in granulometric and thermal segregations. This guaranteed the continuity of the laying, giving more regular, durable surfaces and meeting the comfort and quality standards required in long-term contracts.

The fair had attendees from 25 countries in South America (53.5%), North America (19.7%) and Asia (15.7%) who toured the immense pavilion where more than 300 brands presented their latest innovations.
