The maximum particle size of the AP5 is 5 mm, the maximum dry density is 1. Conversely, little rutting was observed in the three sections stabilised with foamed bitumen and 1.

The final cross section adopted in all pavement sections is shown in Figure 3. 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.

FWD deflections at 40 kN before trafficking 0 load cycles and after 1×10 6 load cycles. Who would have thought that in our country the technologies to be introduced as modified asphalts based massively? 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 Six pavements were constructed using different contents of bitumen and cement.
The results correspond to deflections measured before the trafficking of the sections 0 load cycles and after 1×10 espuumado load cycles. The model was adapted to describe the rutting development instead of the permanent strain. 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.

Nevertheless, the water penetrated into the subgrade causing swelling of this layer and modifying the final levels of the pavement structure. FWD deflections at 40 kN before trafficking 0 load cycles and after 1×10 6 load cycles Average Rutting The averaged rutting measurements for each pavement section are presented in Figure 5.
Before laying the final surface layer, the sections were cured at ambient temperature for 30 days. Average rutting 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 This paper also serves as a guide to identify potential problems to highway agencies in their MEPDG calibrations. 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.
The design engineers have proposed and accepted new technologies, builders have art equipment incorporating the first world asfalfo and we are encouraging, but we shake the pulse, to innovate. Results showed that surface deflections decreased at sections with higher bitumen contents.
The first model described the stable and unstable rutting of the pavement sections while second model only considered the stable phase in where a steady increase in rutting with the number of cycles is observed. The pavement test results presented asdalto that stabilisation using FB and cement improved the performance of the pavements. Details of the structural design are espmado 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.
We thank our customers for the continued trust placed in espumad company to realize the implementation of new technologies in Uruguay. A paver was used to place the basecourse material and a steel roller was used for compaction. The approximate thickness of this surface was 20 mm.
AustroadsPavement Design: Furthermore, New Zealand imports crude oil and therefore its production costs for bitumen are highly dependant on international oil prices. In last December he was terminated the reference work and drove around axfalto full, being able to observe the same high quality in all its aspects. All sections were sealed with a single coat chipseal. Cold in place recycling of pavements using foamed bitumen is a construction technique that reclaims the existing distressed flexible pavement, simultaneously adding stabilising agents to improve the properties of the reclaimed material.
Accelerated loading was applied to the pavement structures and the pavement responses, such as surface deformation espumavosurface deflections and strains, were periodically recorded during the execution of the test. Research has demonstrated that pavement recycling using foam bitumen reduces energy and oil consumption Thenoux et al.
The first sections of pavement recycling foamed bitumen are a reality and are projected as an economic and sustainable solution for the rehabilitation of roads.

The top mm of the subgrade was clay, extended in lifts ofand mm, and compacted using a roller available at CAPTIF. After a week to allow the chipseal to set up, all sections were surfaced with a skim coat of AC10 hot mix covering the top of the chipseal.
Also looking to expand the range of work during cold seasons. It is very important that 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. They were also required many hours of training, briefings and of course hard to successfully implement this advanced technology work in the country. We must become conscious that interventions at the right time require less investment in maintenance.
The results obtained showed that the aggregate source, 0.

Therefore, the H40 particle size distribution was adjusted using an AP5 crusher dust to bring the asflto into the recommended grading zone. The unbound section B00C00 shows considerably higher deflections in comparison with the other sections. Conversely, no cracking was observed in sections B14C10 and B28C The results showed that 2. In this phase, a full factorial experiment consisting of four gradations of a typical aggregate source, and three levels of fibre no fibre, fspumado.
