Abstract:

This research project developed a PWL system that the Nevada DOT can effectively implement on the construction of dense graded HMA mixtures. The PWL system includes pay factors that are based on pavement performance indicators such as rutting and cracking. In addition, the developed PWL System is incorporated into a user-oriented software that is capable of analyzing the relevant data, establishing the PWL values, and applying the appropriate pay adjustments. The research was completed over three phases: Phase I - Review of Existing PWL Specification Systems: this phase reviewed several PWL specification systems for HMA construction. Based on the findings of the review, the research team recommended the general framework of the PWL system to be developed in Phase II. Phase II - Develop the PWL Specification System: this phase developed the PWL system. The developed system uses several materials and mixtures properties to identify the PWLs for all sub-lots and lots of HMA mixtures. Weight factors are identified for each of the materials and mixtures properties leading to the development of a single PWL for each lot within a construction project. Phase III - Implement the Specifications: this phase will implement the developed PWL system on several NDOT projects and uses the data from these projects to fine tune the system. This report is accompanied by a PWL software which conducts all applicable calculations.
