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.
