During our visit to the city of Punta Arenas, they took us to the first and continuous kilometer zero of the southern hemisphere on the rock of Puerto Bulnes, a fortification built by the Chilean government in order to maintain the military presence in the area.

Our adventure continues and from there we pass through the Strait of Magellan until we reach the city of Ushuaia where we disembark and in a regional walk we effectively reach the first true KILOMETER ZERO in the world, with the interruption of the Beagle Channel only, but after crossing the following 17,500 kilometers we can say that the longest road in the world was traveled.

Complete mistake, the roads were made by men and only in less than 100 years we managed to have that impressive network of communication and development that we need to live better every day, that is why when we arrived at KILOMETRO CERO we certified that a road was already working on Ushuaia, another in the Andes and another in Alaska at the same moment to unite like a great umbilical cord and thus be all users of that wonder.

RECYCLED CEMENT AND TMT ROUTE 15

Molinsur trust GROUP BITAFAL for the implementation of technical TMT on recycled with cement made in Route 15.

Adjusted dosing and construction conditions, has been developed excellently recycled TMD on cement. The combination of these two techniques provide a unique opportunity to build synergy routes in our country.

Recycling Portland cement is carried out very rapidly on which an emulsion is applied IRRIGATION BITAFLEX 65 P25 with sand as curing irrigation. TMD is then applied with 14 to 19 mm and gravillín stone 2-6 mm with posterior irrigation fog, all run on the same day and with the same emulsion BITAFLEX IRRIGATION 65 P25.

The surface quality of TMT shows great cohesion of the whole package, without loss of aggregates and large voids content serve several functions. For one drain water towards the shoulders reducing the "Spray" effect and leaving a proportion of feasible to be filled by binder and thus prevent any errors dose or overlap that can result in air exudates.

The results are already more than validated on Route 15 in other sections own previously executed. It is expected durability of these jobs that we hope will be adopted by more manufacturers in the short term.

NEW TECHNIQUE FOR CEMENT CRACKING CONTROL

Serviam has developed an interesting team to prefisurado recycled with cement.

Drawbacks consabidos generating shrinkage cracks of cemented materials are subject to attack because they can reduce the life of the pavement by water ingress. Usually in our country it has incorporated the technique with a heavy microcracking to mitigate these effects but there are other alternatives globally with specific equipment Compactor.

Serviam company developed a computer adapted to perform a Bobcat injecting the emulsion prefisurado IRRIGATION BITAFAL 65 at a depth of 20 cm each 4 m crosswise.

After initial compaction of the recycled material prefisurado this is done then continue working, leveling and final compaction. Of note is the use of technology to achieve grade project controlled by RF motoniveladora.

Subsequently curing the same emulsion BITAFAL IRRIGATION 65 is performed with quarry dust is released and traffic. By far the results are very good and it shows on the go using technology to control IRI. In the next few weeks they will be starting tasks paving asphalt hot mix in 5 cm surface layer.

We will see the behavior of this technique prefisurado in the future. For now, in every induced cracking and the asphalt it is necessary to prevent water ingress so hopefully a lifetime of work done.

The equipment developed by Serviam has a storage tank emulsion, a positive displacement pump, a wedge (shark fin type) of 25 cm which leaves a pipe 20 cm and a solenoid valve for controlling the dosage from Bobcat.

The fin makes a wedge about 2 cm wide in advancing the equipment is filled with emulsion BITAFAL IRRIGATION 65. Then the material of the side itself closes the wedge and leveling and compaction are performed normally. It can be seen watering cured, made with 1L / m2 of IRRIGATION 65 and 6 L / m2 of dust, marks prefisurado every 4 m in the photos below.
