401.031 Warm Mix Technology The Contractor may place Hot Mix Asphalt Pavement produced with an accepted WMA technology if approved by the Department. Methods or technologies shall generally be at the Contractors option, but will be limited to proven, Agency and Industry accepted practice.

Job-Mix Formula Approval. The job-mix formula (JMF) is the combined aggregate gradation and target asphalt recycling agent percentage established from the laboratory mixture design. 4.2.3. Hot-Mix Asphalt. If the process requires new HMA, use materials meeting the requirements of Section 340.4.3., “Mixture Design,” or as shown on the plans.

The job mix formula (JMF) submittal is the mechanism to confirm that the mix being produced is in accordance with the project specifications. We’ll first define three types of mix designs. Dense-graded mixes are the most common. They incorporate well-graded aggregate and 5 to 6 percent asphalt binder (by weight of mix).

the State Asphalt Design Engineer to revert to the Hot-Mix Asphalt QMS Manual procedures for TSR testing on that JMF. This request shall be submitted in writing and shall include all test result data (Material and Tests Unit Form 612s) performed on the specific JMF. Page 6-27, Article 610-1 Description, insert the following as the third paragraph:

B. Mix Design 1. Asphalt Rubber. Design of the rubberized asphalt chip seal surface treatment shall be the responsibility of the contractor. The application rate of the asphalt rubber shall be from 0.50 to 0.70 gallons per square yard. The application rate of the pre-coated cover aggregate shall be between 30 to 40 pounds per square yard.

Mar 01,  · Hot mix asphalt design by certified laboratory Current sales and use tax rate in effect in the City of Stockton Weight slips for HMA Plant Schedule The Contractor shall transmit each submittal to the Engineer for review and approval with the submittal form approved by the Engineer.

Mix design is a process to manipulate three variables: (1) aggregate, (2) asphalt binder content and (3) the ratio of aggregate to asphalt binder with the objective of obtaining an HMA that is deformation resistant, fatigue resistant, low temperature crack resistant, durable, moisture damage resistant, skid resistant and workable.

New Mix Design is Required •No existing mix design will be accepted. •Gyratory gyration have been changed. •Loaded Wheel Tester (LWT) or Hamburg is required. •Lab Tech to design new mix and all submittal will be done through Site Manager. •District Lab Engineer will approve mix for the validation process.

Welcome to Pawtucket Hot Mix Asphalt Inc. With a half a century of experience in the Road Building/Land Materials Industries, Pawtucket Hot Mix Asphalt Inc. is a good choice for why we should be your home when buying in Rhode Island ( RI ), Massachusetts ( MA ), & Connecticut ( CT ). Pawtucket Hot Mix Asphalt Inc. has a 300-ton Gencor drum mix asphalt plant that was installed new in 2008.

Designs may be referenced from mix designs approved under the previous rules, with the new Gsb value as calculated above being substituted for the old. Affected properties such as VMA, VFA, and FAA shall be recalculated. If all recalculated values fall within specification limits, the design may be used. Otherwise, a new mix design is required.
