Print 50 for treatment DUST

emulsion 50 PRINT BITAFAL Hoping it will be of interest to other municipalities, we extend the invitation to participate, you can write to

Anticipating the arrival of the heat and low humidity environment to multiply the effect of fine suspended, and have been conducting several test sections in different traffic conditions to evaluate their performance and durability.

Were tested dosages of 0.6 to 1.0 L / m2, with the optimum performance for dust control is at low doses and releasable traffic almost immediately and are not accumulation zones emulsion. For all these tests has been carried out prior sweep the surface and has cared moisture in it was low for better performance of the emulsion.

In one of the test sections was used as 2-6 mm gravillín immediate release protection traffic without the gravillín interfere with curing or penetration depth since the absorption rate at the base is very fast. With this technique it is possible to urban jobs without cutting the road in no time.

After heavy rains last week some edges of the test sections were eroded by rain which allowed us to check the depth of action of the PRINT 50 and enclosed in photographs.

We estimate that the lifetime of the dust treatment performed with this emulsion, due to the depths reached, must be above 12 months.

Course Geotechnics Vial

On 6, 7, 8 and 9 September will take place during GEOTECNIA VIAL organized by the Uruguayan Association of Roads.

Exchange table with departmental governments

On July 26 colleagues Quartermaster Cologne approached salons CITEVI shared-time exchange with a focus on current needs and challenges that present themselves to technical and economic level for the municipalities and their jobs from construction vial.

an interesting talk, where they were addressed among others the following topics generated:

* The current problems of rural roads and how to address it in a sustainable manner;

* Final technical solutions as stabilized soil cement;

* Benefits of primer emulsions;

* Surface treatments and the experience in New Zealand;

* New modified asphalts and their applications.

Hoping it will be of interest to other municipalities, we extend the invitation to participate, you can write to lucia@bitafal.com.uy to coordinate day and number of participants. If you wish to address a subject that is not in the proposal, we are open to inclusion and thus answer questions.

MIXTURES WARM: 50 ° C at mixing and compaction less.

Following the way of introducing new technology in road construction in the country, Group BITAFAL made a successful stretch of warm mixtures with Techint SACI Route 9. This time was used on CCS S12 mixture envisaged for section a double innovation and a binder modified crumb rubber was used (BITAFLEX AMC 50) with a reducing surfactant additive mixing temperatures and compaction.

Fue posible bajar ambas temperaturas en 50°C, mejorando los promedios de densidad del tramo respecto al realizado sin aditivo a pesar que durante la jornada de prueba la temperatura máxima ambiente fue de 12°C. Por otra parte se lograron aumentos de productividad de la planta y ahorros verificados de Fuel Oil de un 27% con los cuales prácticamente se repaga el uso del aditivo.

the first tire recycling plant is disused Opens - GreenUr

They accompanying the development of technical research of both companies, the MTOP and an engineer of the supplier of the additive which conducted an extensive temperature control and final compaction work by an electromagnetic hydrometer.

The density values were never below 97%, reaching values of 99.5% in some points, quite superior to those evaluated in the section made without additive. Lubricity the surfactant imparts to the binder as well as an improvement in the adhesiveness between the aggregate and the binder contribute to the economy and efficiency during production and paving mixtures.

The following are some of the advantages of incorporating technology tibias mixtures:

Lower operating cost in factory production due to fuel savings
Increased productivity at the plant, due to mix optimization and ease of mixing the aggregate and binder
Greater workability and compactability of the mixture during its extended
Lower emissions of harmful pollutants into the air, to be applied at lower temperatures
More time between the production of the mixture and its application in the field, which can be translated within reach for longer trucks, and the ability to still compact with 6-8 hours between manufacture and compaction field mixture
The possibility of producing asphalt mixtures during cold weather (below 8 ° C)
The possibility of eliminating other bonding agents such as lime or an adhesion improver, and that the additive is an adhesion promoter
More safety and comfort for workers in the plant and in the field, due to the reduction of emissions and harmful particles in the air
The possibility of constructing a pavement with longer lifetime, less oxidized from the beginning, and lower thermal segregation at the time of its spread.
