Access to quality reports Bitafal Special Asfaltos

We have a new online platform to access the quality reports of our products.

It is accessed from the website of GRUPO BITAFAL section Practice Areas / CITEVI / Lab Reports and there is also a direct access from the home page of the web.

There are monthly folders of all products coded by the corresponding batch number. A modification has been made in the delivery notes delivered with each load and the batch number of each is indicated next to the product.

To access the platform it is necessary to have a password that has been sent by email to our clients. In case you have not received this email, we request that you write to us at bitafal@bitafal.com.uy

We hope it will be useful to you and were open to suggestions to further improve communication.

Ergont continues to expand its fleet.

4 Rhodoss tanker semi-trailers for asphalt transport were recently incorporated.

These are four isothermal tanks with a capacity of 30,000 L with stone wool insulation for the transport of hot asphalt. They also have automatic burners to maintain and heat the product in case our clients require it.

With this new addition, we are going to satisfy the demand for asphalt from our plant and from the customers who trust Ergont to transport asphalt from the refinery.

Course Assessment Roadways

Bitafal said this in the course of UNR graduate of Argentina organized by the AUC in Uruguay.

In the last month, from 26 to 29 June, the Evaluation Course Walkways was performed by professors Marta and Oscar Giovanon Pagola, Institute of Applied Mechanics and Structures (lower) At the University of Rosario.

The course starts demonstrates the commitment that exists in the national road on these issues and attended by representatives from Grinor, CIEMSA, Serviam, CVC and MTOP officials, OPP and IM, in days of intense participation.

Among the topics discussed it is highlighted:

The objective of auscultation of pavements.
Analysis of the different parameters of pavement evaluation: longitudinal deformation (IRI), transversal deformation (rutting, sinking), cracking, bumps and surface defects (exudation polishing aggregates).
Review of the most commonly used for evaluation of these parameters equipment. Exposure of the most modern methods.
combined deterioration indexes: Index state Serviciability Present Index (PSI), Pavement Condition Index (PCI).
Importance of tire adhesion road (Macrotexture and coefficient of friction).
structural monitoring of roads (Benkelman, Lacroix, FWD, LWD).

In conclusion, the importance of assessing roadway stands, both structurally and superficially, to determine the prioritization of improvement projects and efficient maintenance of our roads.

New equipment for slip resistance CITEVI

Release Pendulum TRRL (British Pendulum Friction) to determine the coefficient of slip resistance in path 102.

Following the course Walkways assessment of the AUC, Measuring the skid resistance on asphalt Route 102 was made recently built by company C.V.C. with the British Pendulum CITEVI.

Slip resistance assesses the non-slip characteristics of a pavement surface and is directly related to the micro-texture of the aggregates used. The test consists of measuring the energy loss experienced by a pendulum fitted at its end with a rubber shoe, once it touches the surface to be tested. This loss of energy is registered by a mark on the graduated plate that contains the equipment.

With respect to the study section, said coefficient was determined in the new and in the old asphalt layer. In both cases, the test gave a value between 60-65, with a high repeatability in the measurement. Sections of the Carrasco Airport and the Interbalnearia were also tested, exhibiting similar values. Magdalena Pastorini and Nicolás Vaz from the MTOP were present to evaluate and discuss the results obtained.

Teachers consulted the University of Rosario, Marta Pagola and Oscar Giovanon, confirmed that the value found is good. They also clarified that the value tends to decrease with the level of traffic, and if it remains, it may be due to a not very good Los Angeles wear value, to the extent that the particles suffer small detachments (recovering their microtexture) when At the same time they tend to be polished. Finally, Marta comments that as an example, the Olavarría granite in the Province of Buenos Aires, has an initial value before polishing of the order of 65, and after polishing of 40. That final value of 40 is reached in 5 , 10 or 15 years depending on traffic and dirt conditions on the road.

As a final observation we conclude that the pendulum is very sensitive to the texture: if the mixture was kneaded, but still with exposed aggregates can give similar values. Therefore, to fully assess the slip resistance, it is advisable to supplement it with the patch of sand.

We must pay attention to these factors as they influence the behavior of the tire with the pavement, especially in wet conditions. Laboratory sion It has the equipment available to evaluate this parameter.
