Some Aspects Resistance’s Effect in the Flexible Pavements Recycled with Cement Portland

In the last years, the pavement rehabilitation techniques in Brazil have been improved. New types of recycling appear every year but the problems frequently associated with these techniques and materials should be used in considering its mechanic behavior. In Brazil, two kinds of recycling asphalt pavement have been used in the last five years: foamed asphalt and recycled base course with cement. The recycled base course with cement technique has success because it is very easy and the costs are economical, however, the standards and proceedings recommend that the roadway should not be opened to traffic for seven days. Therefore, this is a big obstacle for using this technique, because it is almost impossible to close part of highway for a week. The time to get the necessary performance is a critical element for adopting this technique even if the cost is lower when compared with others. This paper presents the results of research to study the resistance behavior of specimens of the recycling of the asphalt pavement with Portland cement in terms of the time. Some tests were done: compressive strength, indirect tensile and creep static. The samples were tested after 3, 6 and 12 hours after the mixture of the materials with cement Portland.
