Only the technical results obtained are certifying all these advances.
On the one hand, this intervention makes it clear the maintenance backlog that had this route of great importance for heavy vehicle traffic at the entrances of Montevideo and to the port.
A total number of approximately 5. Extrapolation of rutting measurements using the two-parameter model up to 25×10 6 ESAs 4.
What we have learned we must communicate why We participate in conferences and seminars at national and regional level. The results showed asfzlto foamed bitumen stabilization has an eespumado effect on the performance of the pavements studied, as further detailed in this paper.
Details of the structural design are not presented in this paper, but a mm basecourse combined with a relatively weak MPa subgrade provided a pavement structural capacity close to 1×10 6 ESAs of 80 kN using both the design methods.

Dspumado n is the number of data points, d c is the calculated rutting depth and d mi is the measured average rutting. The placement of the surface layer is also quite advanced and it is expected that the route is completely renovated in a few months.
The first term of the model describes the linear increase of rutting with N on a log Rutting -log N scale. Sparing no technical or economic efforts, the company conducted a site recycling pavement with asphalt foam backed administration.
Extrapolation of rutting measurements using the two-parameter model up to 25×10 6 ESAs. Six pavements were constructed using different contents of bitumen and cement.

For the model fitting the root mean square RMS was used: Who would have thought that in our country the technologies to be introduced as modified asphalts based massively? Therefore, the H40 particle size distribution was adjusted using an AP5 crusher dust to bring the aggregate into the recommended grading zone. When the load was increased to 50 kN another increase in the rutting rate was observed. This paper also serves as a guide to identify potential problems to highway agencies in their MEPDG calibrations.
Rutting modeling of stable and unstable behavior.
The characteristics of the foam were investigated using the foamed bitumen laboratory model WLB10, which has been used by many researchers and practitioners for the production of bitumen foam. To accelerate the surface deformation in these sections it was decided to cut part of the pavement sections down from the HMA surface to the top of the basecourse 50 mm-deep cuts.
After the application of 5, Equivalent Standard Axles ESAsthe sections stabilised with cement only, bitumen only, and the control section all showed large amounts of rutting. Mounted on this platform is a sliding frame that can move horizontally by 1 m. As anecdotario plus all innovations in this work, conducted jointly develop gravillados hot applied in July, during the winter closed season with a very good technical and result only applied at low temperatures in our country Bulletin July All photos: Resources, Conservation and Recycling,16 pp.
The VSD was then used to build contour plots of each pavement section. The results correspond to deflections measured before the trafficking of the sections 0 load cycles and after 1×10 6 load cycles.
For this test we participate in conjunction with experimental technologies, using the universal recognized technology stabilization Portland cement on a stretch of road in Artigas.

The profiles were used to calculate the vertical surface deformation VSD by subtracting the original elevation of each transverse profile before loading minus the current transverse profile.
As we all know, when Espimado is proposed, it does, but beyond personal effort, its staff and technology built in Germany show that can be reconstructed 34 km of a road completely new with a guarantee of over 20 years only working days. The loading speed applied during the test corresponds to The CVC recently started with recycling Route using recycling technology in situ foamed bitumen.
By the end of the test little difference was found in the rutting measurements of sections stabilized with foam bitumen and cement sections B12C10, B14C10 and B28C Fromload cycles after constructing the HMA overlay the rutting increased approximately linearly up to 1. It has been announced by esumado government a battery of proposals from an extra small party for the Intendencias to cope with the deteriorating state of their ways to the extension of the scheme of PPP Public Private Partnerships to rural roads Source: Uruguayans participated more than 15 technicians of various construction companies, MTOP, of Tradinter and Bitafal group.
Thanks to the high yields of the technique is expected to have completed the tasks leaving a strong and flexible for future interventions take place only in the surface layer basis in about a month.
