Superpave ESAL Range mixes in Section 424. Warm mix asphalt shall be defined as the use of an approved warm mix technology in the plant mix at the time of production. This work shall also include the preparation of the underlying surface on which the plant mix is to be placed, including patching and/or leveling as shown on the plans or directed.
Batch type asphalt plant produces asphalt mixtures in batches to ensure the consistency in the mix quality. The plant can be designed with large capacity, ideal for medium to large projects. Due to superior quality of finished products, the batch plant is suitable for paving high-grade roads, such as highways.
Called at various times asphalt pavement, blacktop, tarmac, macadam, plant mix, asphalt concrete, or bituminous concrete, asphalt pavements have played an important role in changing the landscape and the history of the U.S. since the late 19th century.
Asphalt Emulsion Mix (Cold): A mixture of unheated mineral aggregate and emulsified (or cutback) asphalt binder. It can be plant-mixed or mixed in-place. Asphalt Emulsion Mix (Warm): A mixture of asphalt emulsion and mineral aggregate usually prepared in a conventional hot mix asphalt plant at a temperature less than 95°C (200°F). It is ...

For projects in environmentally sensitive locations, the SuperRoadMix can be combined with a mobile or fixed bag filter to contain emission levels to less than 20mg/m³. Collected dust is screwed directly to the mixing section filler weigh hopper on the plant, for reintroduction into the mix.
Dense-Graded Hot-Mix Asphalt (Small Quantity) 1. DESCRIPTION Construct a hot-mix asphalt (HMA) pavement layer composed of a compacted, dense-graded mixture of aggregate and asphalt binder mixed hot in a mixing plant. This specification is intended for small quantity (SQ) HMA projects, typically under 5,000 tons total production. 2. MATERIALS
For those more familiar with Superpave asphalt mix gradations, FAA Gradation 1 is analogous to a 19.0mm nominal maximum aggregate size (NMAS) mix. FAA Gradation 2 is analogous to a 12.5mm NMAS mix, and Gradation 3 is analogous to a 9.5mm NMAS 4.
If you have these mixes already in your ready mix provider's office, he can quickly pull out the design and you can tell him to bring your mix #3 or #5. The standard for designing a concrete mix is ACI 211.1, Proportions for Normal, Heavyweight, and Mass Concrete
Reclaimed Concrete Material - Material Description ORIGIN Two billion tons of aggregate are produced every year in the US. Production of aggregate is expected to reach 2.5 billion tons by 2020, which raises concerns about where the new aggregate will come from.

HMA mix design will be done as usual, and Advera® WMA added after design is completed – no change in mix design is required. If a WMA mix design is required, utilize AASHTO R35 for Superpave mixes and the Draft Appendix to AASHTO R 35: Special Mixture Design Considerations and Methods for Warm Mix Asphalt (WMA) (See Appendix B).
Mix designs can be generated in accordance with Tex-204-F by either department personnel or by a consultant/contractor who is certified by the department-approved hot-mix asphalt certification program. Plant mix or raw materials must be furnished by the contractor to the department project engineer to allow verification of the mix design.
