Determining Lab Mixing and Compaction Temperatures for

Asphalt Institute Technical Advisory Committee Approved 7 December 2016 The Asphalt Institute recommends that, for unmodified asphalt binders, the laboratory mixing and compaction temperatures should be determined where the viscosity-temperature line crosses the viscosity ranges of 0.17 ± 0.02 Pa-s (mixing temperature range) and 0.28 ± 0.03 Pa-s (compaction temperature range).

Block 13 Mix design Historical 13

This material is covered in detail in Chapter 4 “Hot Mix Asphalt Mixture Design Methodology” of the recommended textbook. The objective of HMA mix design is to develop an economical blend of aggregates and asphalt binder. In the developing of this blend the designer needs to consider both the first cost and the life cycle cost of the project.

Pavement recycling guidelines for state and local

The project showed that asphalt pavement recycling was a technically viable rehabitation technique, and it was estimated that the use of reclaimed asphalt pavement (RAP) would amount to approximately 15 percent of the total hot-mix asphalt (HMA) production by the mid-1980s.

HMA Mix Design Fundamentals - Pavement Interactive

The Superpave rotational viscometer specifically tests for mixing/laydown temperature asphalt binder viscosity. Knowing these objectives, the challenge in mix design is then to develop a relatively simple procedure with a minimal amount of tests and samples that will produce a mix with all the above HMA qualities. Basic Procedure
