UPM® Cold Mix asphalt repair material is a cold asphalt patch mix for municipalities, contractors and business owners who need to permanently fill potholes and repair roads. Our skilled laboratory technicians design region-specific formulas to create a custom, high-performing cold patch for asphalt for your area.

Asphalt Rubber Applications • Asphalt rubber is the process of adding recycled, crumb rubber to hot mix asphalt (called dry process) or the asphalt binder (called wet process) to modify the final mixture • Difficult to use in dense-graded mixtures due to residual crumb rubber • Best used in gap-graded type mixtures (SMA and OGFC)

design asphalt content for the asphalt mix that meets the criteria of Superpave. Test Equipment The primary device used in Superpave mix design is the Superpave gyratory compactor (SGC), The SGC is used to produce specimens for volumetric analysis and records data

In the latter part of 1979, the Asphalt Institute began two comprehensive studies of EAM design procedures. The first is an in-house project funded by the Asphalt Institute. The following specific tasks are included: 1. Investigate the use of a range of emulsion contents for preparing trial mix specimens based on residual asphalt

4. Heat the asphalt binder to the mixing temperature. 5. Combine the aggregate and asphalt binder at the selected asphalt content for each sample and mix until thoroughly coated. Include fibers if used. 6. After mixing, age the loose mix for 2 hour per R30. 7. Compact two specimens at 50 gyrations for each of the trial batches. 8.

CONTRACTOR MIX DESIGN GUIDELINES FOR ASPHALT CONCRETE January 4 CONTRACTOR MIX DESIGN GUIDELINES For ASPHALT CONCRETE 1.0 SCOPE 1.1 The Oregon Standard Specifications for Asphalt Concrete 00744.13, 00745.13(a) and 00735.13 require the Contractor to develop the mix designs for ACP, Emulsified Asphalt Concrete (EAC),

The purpose of this 4.5 day workshop is to provide engineers, testing personnel, and inspec basic understanding of the asphalt mix design process. This will be accomplished through a review of materials specifications, test procedures, and general mix design requirements for a Superpave or Marshall volumetric mix design and will include

11.1 Hot Mix Asphalt Plants 11.1.1 General1-3,23, 392-394 Hot mix asphalt (HMA) paving materials are a mixture of size-graded, high quality aggregate (which can include reclaimed asphalt pavement [RAP]), and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA. Aggregate and RAP (if used) constitute over 92 percent

HMA Mix Design. HMA Mix Design is the process of selecting properly graded aggregate materials and an appropriate asphalt content that will function under

Cold emulsion mixes are basic aggregate-asphalt emulsion mixes classified by their use, composition and storability. Mix designs are required to determine the grade and percent of emulsion used, as well as the workability, stability, strength and moisture susceptibility. Mixes are designed for purpose and climate.

6. Submit the mix design report, and representative materials when requested or required, to the department for review per 866.2.5. Additional guidance for materials selection and component composition involved in the mix design process can be referenced in, but not limited to, the following: - Superpave Mix Design Manual SP-2 (Asphalt Institute)

The 7 th edition of MS-2 Asphalt Mix Design Methods marks the 56 th year of continuous publication of an Asphalt Institute mix design manual. The manual is a practical guide based on proven technologies, incorporating the most current information available at the time of writing.

FREE Asphalt Mix Design Software Updated The Asphalt Pavement Alliance introduces the latest version of a widely used mechanistic-empirical approach to averting cracking and rutting. Developed at the National Center for Asphalt Technology at Auburn University in Alabama, PerRoad uses the mechanistic-empirical (M-E) design philosophy to estimate

Samples of asphalt mixtures were prepared at four different asphalt contents by weight of asphalt mix mass (5%, 5.5%, 6%, and 6.5%), with three replications per asphalt content. For base asphalt cement and each modifier concentration, one asphalt cement content was chosen, which met the requirement of Superpave mix design 4% air voids.

Hveem mix design is still used in California and other western states. Marshall mix design was originally developed by a Mississippi State Highway Departmen t Engineer, Mr. Bruce Marshall, and later refined in the 1940s by the Corps of Engineers for designing asphalt mixtures for airfield pavements. The primary features of Marshall mix design are a
