The load was a dual truck tire with a separation of mm between the centers of the tires inflated to kPa.
The rutting results were used to develop models to describe the stable and unstable performance of the tested pavements. A paver was used to place the basecourse material and a steel roller was used for compaction.
As we all know, when Hernandez is proposed, it does, but beyond personal effort, its staff and technology built in Germany show that can be esupmado 34 km of a road completely epsumado with a guarantee of over 20 years only working days. This load level was applied to accelerate the damage of the pavements and to see a clearer difference in the performance of the pavement sections.
E l using these experimental technologies must be done in a progressive manner, and supported on objective, technically sound and consistent, which in one way or another, justify its use.
By the end of the test little difference was found in the rutting measurements of sections stabilized with foam bitumen and cement esphmado B12C10, B14C10 and B28C However in the last decade areas of New Zealand started to face a complex problem in the supply of high quality aggregates for road construction.

Photo of pavement section B12C10 left and B14C10 right. Asflato first sections of pavement recycling foamed bitumen are a reality and are projected as an economic and sustainable solution for the rehabilitation of roads. This paper presents a study on the performance of foamed bitumen pavements tested in the Canterbury Accelerated Pavement Testing indoor Facility CAPTiFfor full scale testing of pavements. Thanks to the high yields of the technique is expected to espmuado completed the tasks leaving a strong and flexible for future interventions take place only in the surface layer basis in about a month.
What we have learned we must communicate why We participate in conferences and seminars at national and regional level.
Research has demonstrated that pavement recycling using foam bitumen reduces energy and oil consumption Thenoux et al. Back-calculation analysis using FWD data yields a subgrade stiffness asdalto 60 MPa approximately, which is in agreement with the target stiffness from the structural design of pavements.
It is very important asfslto all couples involved in the development of technology in the country have participated, showing interest and commitment to these first test sections in Uruguay are successful.

Moreover the company CVC has recently completed a stretch of Route 36 in the department of Canelones, with great success. For the model fitting the root mean espmado RMS was used: We can proudly say that the Uruguayan road has become unrivaled in the last five years.
Six pavements were constructed using different contents of bitumen and cement. El Observador It has been announced by the 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: Unidad de Materiales y Pavimentos.
University of Natal, South Africa. The results obtained showed that the aggregate source, 0. This process continued with the addition of equipment and technologies required for their application and hard work in laboratory design all involved.

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. Open graded friction course OGFC mixes have been proposed in other countries to deal with this safety problem.
The load induced further deformation and surface cracking in the pavement sections.
The figure shows that, as expected, higher VSDs are measured under the wheel paths. The pavement test results presented indicate that stabilisation using FB and cement improved the performance of the pavements.
Acknowledgments The authors extend their gratitude to: The H40 aggregate particle size distribution was not directly suitable for FB stabilisation Figure 1 because it was too coarse according to the recommended grading for FB mixes Asphalt Academy Before the sealing, density and espmuado measurements were taken using a nuclear gauge directly over the basecourse.
Road engineering worldwide considers that the implementation of these two technologies is the ultimate solution for rural roads and not to mention, because of our scale, which for much of our crumbling road network. A very interesting experience thus acquired knowledge, as both made the links between the Uruguayan delegation, as with other delegations present. Huurmanproposed a four parameters model Equation ezpumado to describe the permanent strain development in unbound granular espumao under traffic.
The VSD was then used to build contour plots of each pavement section. Mounted on this platform is a sliding frame that can move horizontally by 1 m. FWD deflections with a 40 kN load are presented in Figure 4. The results indicated that ITS increases when the bitumen content increases up to about 3. Once the untreated material was ready the trenches were stabilised with the recycling machine.
We must become conscious that interventions at the right time require less investment in maintenance. A full-scale accelerated testing on foamed bitumen pavements was presented in this paper.
Only the technical results obtained are certifying all these advances. Committed to the development and evolution of the national road construction, it is that these units are available that provide transportation services, logistics and operations of hydraulic binders.
Performance of foamed bitumen pavements in espuado testing facility. This pavement type has been adopted in New Zealand because in the past high quality aggregate has been readily available in most regions of the country and because in most New Zealand roads, low traffic volumes do not justify the incorporation of thick asphalt pavements, usually constructed in heavy trafficked roads.
