The optimum binder content of the HMA is highly dependent on aggregate characteristics such as gradation and absorptiveness. Aggregate gradation is directly related to optimum binder content. The finer the HMA gradation, the larger the total surface area of the aggregate, and the greater the amount of binder required to uniformly coat the

Hot-Mix Asphalt (HMA) 101 Description: Understanding the basics of hot-mix asphalt – its composition and the importance of proper transporting, placement and compaction – is a vital necessity for anyone involved in the construction or inspection of asphalt pavements. HOT MIX ASPHALT PAVEMENT DESCRIPTION 450.20 General. This work shall consist of producing and placing Hot Mix Asphalt (HMA) pavement. HMA mixtures shall be composed of the following: Mineral aggregate, mineral filler (if required), Performance Graded Asphalt Binder (PGAB), and as permitted, reclaimed materials (limited to 7 hours ago · A 38-mm thick HMA surface course is to be designed to carry 15,000,000 ESALs during the life of the pavement. A 9.5-mm nominal size aggregate is required. The aggregates shown in Table 4-14 are available for use. The control limits and restricted zone boundary are shown in Table 4-10. superpave asphalt mixture design, hma binder course, pg 64-22, 10 to < 30 million esals, 19 mm mix: 1188.000: ton : 2400: 2409-6770: superpave asphalt mixture design, hma binder course, pg 76-22, 10 to < 30 million esals, 19 mm mix: 30.000: ton: either: 2500: 0409-7470

The full Superpave QC/QA (new certification) course lasts five days, the Superpave QC/QA re-certification course runs for two days, and the HMA Aggregate Consensus Tests, TSR, and Binder Ignition Oven courses are one day long. The Superpave QC/QA courses are divided into modules as shown below.

The vendor shall provide and apply bituminous tack coat to all existing hot mix asphalt pavement surfaces to be overlaid in this contract (and to all hot mix asphalt pavement surfaces included in this contract that will be overlaid by this contract). Tack coat shall meet the material requirements in Section 407-2 of the Standard Specifications.

Hot Mix Asphalt Base Course (HMAB Course). Dense-graded HMA primarily used for binder courses and HMA base courses. The nominal maximum aggregate size is 1 inch and compacted lift thicknesses should be between 2.5 and 6 inches. This is the HDOT designation for what this Guide calls ACB. Asphalt binder content ranges from 3.8 to 5.7 percent by

Please confirm that this is correct. If 3/4' thickness is correct will a different mix design be required? The Hot Mix Asphalt (HMA) Level 2 Job Mix Technician course is intended to cover the concepts and preparation procedures of HMA job mix formula (JMF). Individuals who complete this course will be certified to perform HMA Level 2 Job Mix Technician duties for SCDOT projects. Mar 20, 2020 · FLEXIBLE PAVEMENT HMA: Topic 631 - Types of Flexible Pavements & Materials Index 631.1 - Hot Mix Asphalt (HMA) HMA consists of a mixture of asphalt binder and a graded aggregate ranging from coarse to very fine particles. HMA is classified by type depending on the specified aggregate gradation and mix design
