GROUP OF PAVING EXPO BITAFAL PARTICIPATED

From day 27 to August 29 was held the Expo & Conference Paving South America, in San Pablo.

Pavement recycling with rejuvenating emulsions, micropavimentos high performance membranes antireflection thin cracks. These are some of the titles of the talks that were presented last August in the Paving Expo&Conference San Pablo, where we had the pleasure to attend.

The note then delves into the most relevant topics of the event that will mark the future of sustainable techniques in our region.

This conference consisted of workshops specific technologies where the field specialists unveiled the latest advances in products and application techniques. During the three days of Congress they were presented about 2300 and about 8800 people attended the various workshops.

Among the most relevant topics, deep recycling with emulsion can be highlighted. This technique, which is becoming more important every day, was explained in detail by experienced professionals, such as Tim O'Connell of Ingevity. Among the benefits that it highlights is first of all the fact that a recycled emulsion base provides superior strength and flexibility that minimizes rutting, fatigue and thermal cracks. Likewise, it is a cost-effective method where all the stone and asphalt material is recovered. For his part, Jorge Escalante from TDM commented on the Peruvian experience with this technique on a high-traffic highway in his country.

Sustainable techniques mentioned above that in the past were not taken into consideration for technical and economic reasons, they are stomping the region. It was clear from the conference view is set to more sustainable alternatives where bet to improve the bases and very durable thin layers which are applied as rolling.

We thank our friends Betunel e Ingevity for kindly inviting us to the event. For those interested in updating their knowledge on these issues, the next edition will be held in the 1 to 3 September 2020.

INAUGURACION ROUTE 8 melo-Aceguá

the section built by the company CVC on Route 8 connecting Melo with the Brazilian border was opened.

On 10 September the ribbon cutting took place in the village Isidoro Noblía found in the newly renovated section. The ceremony was attended by Minister Victor Rossi, the Mayor of Cerro Largo, Pablo Duarte, representatives of the company, DNV and other national and local authorities as well as colleagues and friends.

The section was recycled in 9 m and then a road of 7.2 m was conducted in double bituminous treatment with fog. In some sites existing sewers widened and conditioned with asphalt some sections as traversing Noblía.

Recycling cement was performed in 25 cm depth giving a great bearing capacity to stretch. irrigation curing is then performed with

Recycling cement was performed in 25 cm depth giving a great bearing capacity to stretch. irrigation curing is then performed with Emulsion IRRIGATION 65 which allowed the release to traffic during last winter without problems. Bituminous simple treatment was performed on the 9 m wide while the fog twice using only road always Emulsion IRRIGATION 65 P25.

Exudation problems that appeared last year were already controlled in January and hopefully a good pavement performance this season and next summer following. The sealed surface texture was evenly across the entire width making resemblance to a asphalt.

We commend the company for having completed all the sections in very good condition and high quality. It is expected durability and enjoyment for users who can circulate in a safe and comfortable route.

PG 70-28 asphalt NEW

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.
