| الوصف: | Asphalt cold mixes become attractive as an alternative compared to asphalt hot mixes due to the increase of the necessity to find economic solutions in the investments at the same time to have a sustainable development. For this reason, it is considered important for Costa Rica to begin with the revision and study of the advantages in the application of this technology. The production of asphalt cold mixes implicates savings in energy consumption and the reduction of noxious fumes and dust. An advantage of this type of mix is their versatility, which permits the use of a large variety of aggregates and emulsion types, also they can be used in diverse environmental conditions. For surface applications, dense graded cold mixes are used for light and medium traffic, but open graded are used for heavy traffic. For the reparation of potholes, cold mixes are a good selection as long as the material adjusts the pavement characteristics. On this research, the asphalt cold mix technique was studied in the possible uses and specifications to ensure a correct application in our environment. Also, a review of the laboratory tests that are used for mix design and to characterize the performance, was made for both the components and the asphalt mix. After the theoretical approach, it is necessary to emphasize the construction process to produce a long-lasting asphalt cold mix. The decision to use these mixes depends on the following considerations: the technical-economic comparison, the importance, and the location of the construction site, traffic, and climate conditions among others. The objective of this study is to find the basis for this maintenance technique to be fully spent in conjunction with all the advantages it brings. |
