Bitafal Special Asfaltos incorporates a new high-quality modified bitumen called PG 70-28.

The new surface has excellent results in laboratory, achieving resistance to permanent deformation and the like fatigue one asphalt AM3. If you are perform traditional tests it can be classified as an asphalt AM2 (almost AM3) of the IRAM 6596 standard but is a performance grade asphalt PG 70-28 E (for extremely heavy traffic).

And there are several works that are using this new alternative modified asphalt on the one hand is being used in the retreading on concrete Route 8 by Tracoviax and CVC and another is beginning to be used in the reconstruction of Route 14 you have to perform the PPP Circuit Vial 3 by the Espina-Copasa consortium.

At 12th Congress of the Road Uruguaya the benefits of this new modified asphalt and comparative studies with other asphalt cements were presented at the square.

On Route 8, it is conducting a retreading over the existing concrete section of Mataojo Solis - Minas. First a base layer of 5 cm and then a 4cm surface, both prepared with the asphalt PG 70-28 (AM2).

The mixing temperature is in the range of 160 ° C, maintaining the characteristics of a conventional asphalt work and high performance work to achieve good workability in the vicinity of 150 ° C.

Both companies are making a very good job in both manufacturing and laying and compaction of asphalt mixture which is reflected in surface quality, both macrotexture and IRI. We emphasize safety equipment used as mobile radars and donkey backs of much needed in a high traffic route. Moreover, for the roughness of the section are being used skates 6 m with sensors coupled to the terminating and results feel gait.

We thank the companies and the MTOP the offered confidence.
