Abstract
This article discus about the heavy industrial asphalt pavements structural design, through the application of a mechanistic approach for the analysis and design. The heavy industrial pavements are principally characterized for its heavy traffic loads and a relative low number of repetitions. The current design practice is based on purely empirical principles, which have been developed for the design of roads asphalt pavements, and are not applicable for the design of heavy industrial pavements. So, this article contain a full study about the empirical - mechanistic design method, applicated on heavy industrial asphalt pavements analysis and design. Every stage of the method are described, and inputs like traffic loads, material properties and temperature distribution are characterized. A description of the software HIPAVE is presented, which is a software from Australia and was developed for heavy industrial asphalt pavements analysis and design. Also, the applicability of the method and the future research lines for to improve itself are discussed. In complement, a application example is presented, which consist in the design of a asphalt pavement structure, for a sawmill's yard located in Arauco province.
