Hawaii Asphalt Pavement Association Executive Director John Young explains components of a job mix formula for dense-graded mixes–a must read introduction to JMFs.. The objectives of paving with an asphalt mix are to get a smooth, quiet ride with good strength, stability, and durability; with no rutting, shoving, or flushing; and with no cracking or raveling.

If the mixture does not pass performance tests, the entire mix design process is repeated. This approach is currently used in Illinois, Louisiana, New Jersey, Texas, and Wisconsin. Performance-Modified Volumetric Mix Design. This approach begins with the Superpave mix design method to establish an initial aggregate blend and asphalt content.

It is recommended that, for a hot mix surface, a polymer modified asphalt binder material be applied to the full depth reclamation surface prior to paving to improve the flexibility of the bond response to climatic and traffic loads (Morian, et al., 2012).

Since 2008, NJDOT has been collecting mixture performance test data on a number of their mixes with varying amounts of RAP and mixes without RAP. The approach is that if an HMA plant can produce an HRAP mix that meets the performance characteristics of a mix, NJDOT is ok with that mix regardless of how much RAP or what binder grade is used.

B3 = % asphalt content at specified percent air voids in the total mix. 11.9 EVALUATION AND ADJUSTMENT OF MIX DESIGN The overall objectiveof the mix design is to determine an optimum blend of different components that will satisfy the requirements of the given specifications (Table 11.3). This mixture should have: 1.

For all of the "specialty" asphalt mixtures utilized by NJDOT, performance-based testing is conducted on the mix produced during mix design, test strip construction, and project production to ensure that the mixture meets the performance requirements and that the asphalt mixture produced for the project continually meets the specified performance criteria.

ASPHALT PAVING MIXTURES The pavement design requires the proper hot mix asphalt paving mixtures for the base and surface pavements. It is important that a Job Mix Formula for the paving mixture be established for and approved by the engineer. A reputable hot mix asphalt producer,providing standard

30-11-2019· Asphalt mixture design with Recycled Asphalt Shingles. The baseline asphalt mixtures utilized in the study are shown in Table 1. However, designing asphalt mixtures with Recycled Asphalt Shingles (RAS) takes special care to ensure the hardened asphalt binder of the RAS does not create potential fatigue and thermal cracking issues.

asphalt mix design system was envisioned to include three levels based on the design traffic for the pavement. Level I was envisioned to be for low traffi c pavements and the mix design requirements would be primarily based on traditional volumetric properties. Level II would be used for the majority of projects that carry moderate traffic
