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.
