ROUTE 3 DUPLICATION IS A REALITY

The works of Circuit 7 being carried out by Serviam and CVC are progressing at a very good pace

The project includes the duplication of roads in route 3, between routes 1 and 11, a bypass through the south of the city of San José de Mayo and a new bridge over the San José river. The section to be duplicated has an extension of 25 kilometers and about 8 km are close to being enabled just a few months after the start of the works.

The asphalt mix project is carried out entirely with modified asphalt supplied by Grupo Bitafal and the shoulders were made with a Cape Seal with modified BITAFLEX emulsions.

We thank the companies for the confidence they have given in supplying such an important input for their work.

The sections that are ready to be inaugurated are from Route 1 to km 73 executed by Serviam and the section from km 87 to the departmental capital together with the concrete pavement and roundabouts of the city of San José executed by the CVC company.
In both sections there were various challenges to overcome such as the transplantation of dozens of palm trees, the use of new equipment and technologies such as the transfer that Serviam incorporated (HC #130) for the execution of the asphalt layer.

The use of the transfer allows an excellent homogeneity of the laid mixture as well as a surface regularity (IRI) below 1 that is noticeable when walking on the pavement. Congratulations to the entire Serviam technical team for the excellent work done.

Regarding the concrete section of CVC, it is worth highlighting the solution to the drainage as well as the interaction of the route with the shops and the incorporation of two large roundabouts in an area of high, heavy and slow traffic such as the pass of Route 3 by the city of San José. As for the cemented base, it was made on the project dimension and then trimeated with the 3D milling machine to achieve an excellent support IRI. The concrete pavement was made between July 16 and August 25, in just 40 days, there were 44,000 m2 with curbs with heavy traffic and short days. We congratulate the efforts of the company for such an achievement.

INAUGURATION OF ROUTE 104 AND ROUTE 10

The synergy between recycled cement and surface treatments show that a route can be rehabilitated at low cost with high performance and quality

Last January 28 The official inauguration of the works took place at the intersection of both routes, in front of Manantiales beach. The Minister of Transportation and Public Works, Luis Alberto Heber, the Mayor of Maldonado, Enrique Antía, the Director of Roads, Hernán Ciganda and the Directors of the company participated in the meeting.

There are several accolades that the Serviam company has received for the Capeseal that was carried out in more than 33 km of route that were rehabilitated in just 3 months. Not only for the quality of the finished work but also for the speed of execution as well as for the aesthetic and functional improvement of one of the main tourist corridors in Punta del Este.

As we discussed in the Bulletin # 118, the works on Route 104 consisted of cleaning the strip and deepening the gutters as well as the surcharge of between 15 and 20 cm of roughness that was recycled with cement along with the old existing bituminous treatment.

To control cracking, transverse cuts were made with emulsion IRRIGATION BITAFAL 65 with a team specially designed for it. The curing irrigation was carried out with Emulsion IRRIGATION BITAFAL 65 and crushing sand providing excellent adherence and a very good performance as protection of the stabilized base.

Finally, the Capeseal type paving was carried out with a simple bituminous treatment with emulsion. IRRIGATION BITAFLEX 65 P40 and a cold micro-agglomerate with emulsion BITAFLEX MICRO 62 P25

A roundabout was made at a black point on the route and all the signage was renewed by applying highly durable thermoplastic paint, studs and highly reflective signage.

The section of Route 10 from 104 to the entrance to José Ignacio was recycled in 15 cm with Portland cement and then Capeseal as a tread layer.

Both routes achieved an improvement in roughness and slip resistance, as well as a finish similar to asphalt pavement with great contrast to the signage, which translates into improvements in road safety. In addition, an important structural improvement was made that will allow a high durability of the rehabilitated sections.

ROUTE 104 REHABILITATION

Serviam began the rehabilitation works that will culminate before the tourist season

The route that connects Routes 9 and 10 at Manantiales is being rebuilt along its 15 km length through recycling with Portland cement and a Capeseal as wearing course, similar to what was done on Route 60.

It is an ideal solution due to the aesthetic and functional quality of the combination of treatments for a route that has high light traffic in the summer season.

The works began with a strip cleaning and ditch deepening as well as the surcharge of between 15 and 20 cm of coarse that is being stabilized with cement together with the existing old bituminous treatment.

As in the rehabilitation of Route 18 (Making Paths Newsletter #102), a series of transverse cuts with emulsion is made to control cracking. IRRIGATION BITAFAL 65 with equipment specially designed for it. A radiofrequency motor grader guidance system is also being used that allows a great improvement in the roughness of the section that will later receive a surface treatment.

Irrigation Curing with Emulsion IRRIGATION BITAFAL 65 and grinding sand has excellent adhesion and performs very well as a stabilized base protection.

In the next few days, the Capeseal type paving works will begin with a simple bituminous treatment with emulsion IRRIGATION BITAFLEX 65 P40 and cold microagglomerate with emulsion BITAFLEX MICRO 62 P25.

We will keep you informed of the development of the work in future editions of our newsletter.

RECYCLING AND CAPESEAL ROUTE 60

The works mentioned in previous bulletins (Bulletin # 98 NOTE: Capeseal on Route 60) Have come to an end and the result is really very good.

The recycling works Portland cement and the Capeseal provided as wearing course have culminated in this work quality that carried out Serviam. Aesthetic and functional completion of the section is excellent and we recommend those not familiar with the technique of Capeseal visit the section from Sugarloaf to the city of Minas.

It is for the group BITAFAL proud to have been involved in the whole process, from the dissemination of the aforementioned techniques in lectures, conferences and in our book "High Performance Surface treatments"To see it come true with the quality achieved. Thank provided Serviam confidence in our products and services in each of the construction phases of the stretch.

Capeseal technology tendered by MTOP on routes 12 and 108.

Capeseal technology takes hold in Uruguay with the first project awarded in this mode by the MTOP.

The company Emilio Alvarez Diaz S.A. it's found rehabbing a stretch of 32 km of Routes 108 and 12 in the Department of Canelones. The work consists of a charge in some areas and then performing a site recycling in 20 cm depth with 3% Portland cement and subsequent Capeseal treatment involving the execution of a simple treatment and bituminous cold microsurfacing above.

In this case the application of simple treatment is performed with emulsion IRRIGATION BITAFAL 65 at between 1.2 and 1.4 L / m2 and a gravel 14-20 mm applied between 13 and 15 L / m2. Once cured, the treatment is swept and the company R & K Engineers applies a cold emulsion microsurfacing BITAFLEX MICRO 62 P25 at a rate of about 14 kg / m2. The aesthetic completion of the work resembles an asphalt binder and provides an excellent Macrotexture giving greater security to the pavement.

There are several sections already implemented this technology as Route 55 or Route 69 successfully suggesting that the development of the same in the coming years will grow. So soon in the coming months the company Served S.A. You will be running a section of Route 60 Route 12 and in the Minas with Capeseal.

We believe that it is essential to make a good stable base for the Capeseal will play as a surface treatment lasting many years both in function and waterproofing in adherence with the tire without losing the aesthetic quality.

The use of modified emulsions for both simple treatment as for microsurfacing use should be binding as the adhesion achieved with much higher aggregate in respect to unmodified emusiones. In turn the selection of aggregates for both treatments should be carefully performed for an appropriate duration.

We hope to inform them about future works Capeseal in the coming months and leave you with some pictures of the work done.

CAPESEAL on Route 55

The development of technology Capeseal continues to grow in Uruguay.

recently we visited the stretch of Route 55 Capeseal in the company by Emilio Alvarez Diaz S.A. and could verify the quality of surface finish achieved with the cold microsurfacing on a simple surface treatment.

The microsurfacing was executed by the company R & K Engineers using Bitaflex Micro emulsion 62 P25 was adjusted to regulate the cutting time due to weather and the type of water used conditions.

The result is visible, complete homogeneity across the surface, both in appearance and in the macrotexture is achieved. Besides excellent adhesion it is verified by the simple surface treatment.
