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.

CITEVI gives a great step incorporates a Rheometer (DSR)

We are pleased to inform our readers that we are adding to our Research Center (CITEVI) Court Dynamic Rheometer (DSR for its acronym in English).

In a natural evolution of a company committed to the development of national road company, it's time to incorporate a computer that involves a before and after in the knowledge of the binders we handle.

This sophisticated equipment allows to know the performance of asphalts much of its viscoelastic range. Mainly we are concerned in these latitudes, that is at medium and high temperatures.

The team selected after several months of visits to research centers in the region and the US, is a Anton Paar SmartPave 102 with all accessories to perform the usual tests standardized by AASHTO and other agencies both America and Europe.

It is expected to be operational by August so we'll have more news on this in future editions of this Newsletter.

VISIT TO THE UNIVERSITY OF MONTEVIDEO CITEVI

Students Career Civil Engineering at the University of Montevideo participate annually in a lab course Civil Laboratory III on aggregates, binders and asphalt mixtures in our facilities.

It is the fourth year that this laboratory is provided in the sionWhere an approach to building materials pavement comprising an asphalt mixture, testing quality control thereof, the design criteria of the mix, an evaluation of its mechanical properties and details of it gives the laboratory practical activity in respect of which represent its future activity, such as road builders.

The activity is focused on the design of an asphalt mixture according to the Marshall method, carrying out a theoretical review of the method as well as the national regulations. Subsequently, asphalt mixtures with different asphalt contents are made in the laboratory and test methods are evaluated to determine the characteristics of the mixture and the aggregates used. Once the capabilities of each of the systems have been determined, students process the information and interpret the results. In addition to carrying out classic tests, such as Los Angeles attrition or the dosage of mixtures by the Marshall method, it is intended to bring students closer to new testing technologies such as Microdeval and to comment on other existing dosage methodologies.

We thank the Quím. Paula Morales for the time given for the realization of this practice as well as the UM for the trust given to CITEVI industry as a technical reference.

THE IMPORTANCE OF PORTLAND CEMENT STABILIZED.

Our company in 2013 introduced the first Uruguay Wirtgen WR2000 stabilizer knowing that coming times of change in our industry due to increasingly tight budgets to meet a growing demand for road maintenance.

Moreover, the provisions of Dinama and Dinamige for quarrying are increasingly restrictive implying that these technologies, reuse of existing materials, are here to stay.

The more than 14 machines that are operating in our place to prove it. more economic and lasting foundations are achieved using existing materials and also with yields never imagined execution.

This technology allows us to think of other alternatives for pavement design, especially in the surface layers, which are not disseminated by the lean life they had in defective granular bases.

It's not new, but We are convinced that the foundations of our roads are the foundation and the life of asphalt which we place on them.

It is our vocation known surface treatments, very successful experience in new binders and search for new alternatives of implementing them prove it.

It is a technology that fits perfectly with the costs that Uruguay can pay for your roads and excellent cost / benefit based on traffic routes we have in our relationship.

We are studying sion All manual published in the roads of Australia, New Zealand and South Africa where more than 90% of the kilometers are executed surface treatments and where they used the stabilized with cement massively.

This work is being developed thoroughly and bringing it closer to the realities of this side of the southern hemisphere to transmit knowledge to the sector being adquiriendo.Prontamente be informing them about the progress of this work.

VISIT TO THE UNIVERSITY OF MONTEVIDEO CITEVI

For the third consecutive year we visit students of Civil Engineering at the University of Montevideo in our facilities. The activity is part of the course of Civil Laboratory III specifically on aggregates, binders and asphalt mixtures.

In the same an approach is given to building materials pavement comprising an asphalt mixture, testing quality control thereof, the design criteria of the mix, an evaluation of its mechanical properties and details of the activity laboratory practice compared to those who represent its future activity, such as road builders.

The activity is focused on the design of an asphalt mixture according to the Marshall method. In principle, a theoretical review of the method and national regulations was carried out. Subsequently, asphalt mixtures with different asphalt contents were made in the laboratory and test methods were evaluated to determine the characteristics of the mixture and of the aggregates that were being used. Once the capabilities of each of the systems were determined, the students processed the information and interpreted the results.

In addition to performing conventional tests, as wear LA or mixtures dosing by the Marshall method, seek to bring students to new technologies and assays as Microdeval comment on other methodologies existing dosage.

During the day also made visits to industrial plant Bitafal Special Asfaltos and other technologies are discussed road maintenance to complement seen in the laboratory.
