ASPHALT MIX DESIGN TYPE MICRO-PAVEMENT WITH ADDITIVES
Keywords:
Pavements, Asphalt Mix, Micro-pavementsAbstract
The pavements must comply with an appropriate useful life time according to their structural design, providing safety and comfort to the users who pass through this infrastructure. In this sense, the objective of this research lies in proposing a micro-surfacing type asphalt mix design with additives based on technical specifications that improve the rolling surface. For this, in the first instance, the bibliographic base of research related to micro-surfacing is analyzed. On the other hand, the physical and mechanical properties of the materials used in the asphalt mix are determined and the optimal percentages of additives used in the asphalt mix are established. The methodology applied in this design is the one stated in the Manual of the North American Institute of Asphalt DESIGN METHODS FOR ASPHALT CONCRETE AND OTHER TYPES OF HOT MIXTURES, recommended and accepted by the Ministry of Transportation and Public Works of Ecuador. The properties of the materials, their dosage and tolerable ranges have been determined according to the requirements.
Keywords: Pavements, Asphalt Mix, Micro-pavements.
