The National Asphalt Pavement Association (NAPA) publication, Warm- Mix Asphalt: Best Practices (2) presents more detailed informa- tion on many of these processes including the types of plant modifications that are needed with each. Table 1 summa- rizes

Marshall Mix Design Procedure. The Marshall mix design method consists of 6 basic steps: selection. Asphalt binder selection. Sample preparation (including compaction) Stability determination using the Hveem Stabilometer. Density and voids calculations.

According to Superpave mix design method, a thermosetting material (Epoxy Asphalt mixture) was designed for surfacing on orthotropic steel deck bridge. Firstly, based on the thermosetting feature, the viscosity increasing law of EA binder was studied by B

The mixing and compaction temperatures determined by this method should not be used to control plant production or pavement construction temperatures. Greater latitude in mixing tem- peratures is necessary in the field to allow for different ambi- ent con

Mix temperature is dependent on the grade of asphalt used in the mix. Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified

Plant Mix Base: A foundation course produced in an asphalt mixing plant, which consists of a mineral aggregate uniformly coated with asphalt cement or emulsified asphalt. Plant Screens: Screens located between the dryer and hot bins, which separate heated

Trinidad Lake Asphalt (TLA) is a natural asphalt that was used in the first asphalt pavements built in the U.S. more than 100 years ago. TLA is still used today in high-stress applications around the world, and it is now produced in a pelletized form to f

plant mixed specimens. All testing shall be undertaken in a laboratory, accredited by NATA for the relevant test methods. Note: All mix designs shall have adhesion agents (concentrated) added to the bitumen Note: Open Graded Asphalt and Stone Mastic Aspha

The Superpave system includes a performance-based asphalt binder specification, a new mix design analysis system, many new test procedures, and new equipment. The first phase of the Superpave Mix Design System was put in place in 1996 with the national ad

Asphalt compatibility Consequences • Colloidal structure parameters from SAR -AD, AFT, DSC and SEC can / could be used to assess compatibility, blending rules and aging effects • Blends of various asphalt bases available in refineries • Virgin asphalt and

SUPERPAVE MIX DESIGN METHOD The Superpave mix design method is a volumetric mix design process. An analysis of specimens and the maximum specific gravity sample are conducted to evaluate such properties as voids in mineral aggregate (VMA), voids filled wi
