After the application of additional accelerated traffic load, section B12C10 started to show surface cracking, while sections B14C10 and B28C10 performed well. Extrapolation of rutting measurements using the two-parameter model xsfalto to 25×10 6 ESAs 4. 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 The results indicated that ITS increases when the asfalo content increases up to about 3.

The top mm of the subgrade was clay, extended in lifts ofand mm, and compacted using a roller available at CAPTIF.

This paper conducts laboratory evaluation of OGFC mixes to determine their suitability and assess engineering properties required to introduce these type mixes in Costa Rican pavement technology.

Uruguayans participated more than 15 technicians of various construction companies, MTOP, of Tradinter and Bitafal group. Who would have thought that in our country the technologies to be introduced as modified asphalts based massively?

However, espymado little rutting was measured during the early stages of the project, the load was increased to 50 kN afterload cycles and again to 60 kN after Nevertheless, the water penetrated into the subgrade causing swelling of this layer and modifying the final levels of the pavement structure.

Asfalto espumado by Lucio Borelli on Prezi

Once the cutting job was finished, water was uniformly adfalto over the surface. Huurmanproposed a four parameters model Equation 1 to describe the permanent strain development in unbound granular pavements under traffic. The unbound section B00C00 shows considerably higher deflections in comparison with the other sections. The VSD was then used to build contour plots of each pavement section. On the one hand, this intervention espumadk 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.

We thank our customers for the continued trust placed in the company to realize the implementation of new technologies in Uruguay. The final cross section adopted in all pavement sections is shown in Figure 3.

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 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: When the load was increased to 50 kN another increase in the rutting rate was observed.

Conversely, no cracking was observed in sections B14C10 and B28C The maximum particle size of the AP5 is 5 mm, the maximum dry density is 1. Extrapolation of rutting measurements using the two-parameter model up to 25×10 6 ESAs. One of espuado key principal goals of pavement asset management is to develop and implement cost-effective pavement construction and maintenance strategies that achieve the required levels of service and performance.

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. The pavement test results presented indicate that stabilisation using FB and cement improved the performance of the pavements. Results showed that surface deflections decreased at sections with higher bitumen contents. 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.

Mounted on this platform is a sliding frame that can move horizontally by 1 m. A paver was used to place the basecourse material and a steel roller was used for compaction. Also looking to expand the range of work during cold seasons. The structural design of pavements was carried out using the South African interim guidelines Asphalt Academy, and the New Zealand supplement to the Austroads pavement design guidelines Austroads, At 2×10 5 load cycles the thin surface layer was overlaid with 30 mm of HMA.

First, the paper deals with the importance of using mechanistic-empirical ME analysis and design models, as opposed to the purely empirical models that have been traditionally used in Latin America and the world. 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 This process continued with the addition of equipment and technologies required for their application and hard work in laboratory design all involved.

The model fitting of the two-parameter model is shown in Table 1 bottom. In this aspect, from asfxlto Bitafal Group to continue innovating bet in real technical solutions for the durability of rural roads.

He BITAFAL group He has supported projects in both asphalt and logistics sion with facilities and equipment for the proposed Route 36 We thank our customers for the continued trust placed in the company to realize the implementation of new technologies in Uruguay.

The model was fitted to the rutting measured at 3×10 5 load cycles 5. Recently they have begun to implement the first sections in situ foamed bitumen. Privacy Center Privacy Policy Cookies asdalto.

This paper also serves as a guide to identify potential problems to highway agencies in their MEPDG calibrations. As anecdotario plus all innovations in this work, conducted jointly develop gravillados hot adfalto in July, during the winter closed season with a very good technical and result espumad applied at low temperatures in our country Bulletin July All photos: What we have learned we must communicate why We participate in conferences and seminars at national and regional level.

The results showed that 2.
