ASPHALT USING SYNTHETIC ZEOLITE AS AN ADDITIVE submitted by SOURAV KUMAR SAHOO in partial fulfillment for the requirement for the award of Bachelorin Technology degree in Civil Engineering at National Institute of Technology, Rourkela, is an authentic work carried out by him under my supervision and guidance.
Adding zeolite in asphalt mixtures saves energy because of lower temperatures for mixing and compacting. Zeolite, especially synthetic, improves resistance to permanent deformation of asphalt layers. ACKNOWLEDGEMENTS The work reported in this paper is a part of the investigation within the research project
Two zeolites differ in their crystalline structures, i.e. one was Na-P1 synthetic zeolite and second was clinoptilolite natural zeolite. Prior to asphalt foaming these materials were additionally soaked with water which resulted in total of

synthetic zeolites. Each of these additives affect the asphalt cement by reducing its effective viscosity, or workability, and allow for adequate mixing and compaction at temperatures significantly less than that of hot mix asphalt.
Jun 20, 2012 A control HMA mixture, WMA with 0.3% synthetic zeolite, and WMA with 0.5% synthetic zeolite were used in the test. Based on the tests conducted, it was found that the WMA mixture made with synthetic zeolite had a higher resilient modulus. For dynamic modulus test, WMA with 0.5% synthetic zeolite have a higher dynamic modulus.
The addition of zeolite allows lower manufacturing temperatures to be used 18,19, 101, and asphalt mixtures containing 0.6% natural zeolite produced fewer

Synthetic zeolites in hot mixed asphalt make compaction simpler and, to some extent, allow for cold weather paving and longer hauls. Did You Know? Clinoptilolite (a naturally occurring zeolite) is used as a soil treatment in agriculture. It is a source of potassium that is released slowly. If the zeolite has been pre-loaded with ammonium, it ...
Jul 01, 2016 Better compactability of mix asphalt samples with NaP1 synthetic zeolite addition than with clinoptilolite might result from textual properties of these minerals. Zeolite Na-P1 material had a 5-time higher specific surface area (94.48 m 2 /g) than clinoptilolite (18.3 m 2 /g) and was a more porous material ( Table 3 ).
Embodiments provide slurries of water and zeolite. These slurries have beneficial properties when mixed with asphalt. These beneficial properties may include extension of the asphalt as well as a decrease in the temperature used to process the cement. In some embodiments additional additives are included, such as anti-strip amines.
Synthetic zeolites are used as additives in the production process of warm mix asphalt concrete. When added to Portland cement as a pozzolan, they can reduce chloride permeability and improve workability. They help reduce the weight and provide slower drying and help with moderate water content, which increases fracture strength.
Leo et al. 14 concluded that the asphalt mixture with synthetic zeolite can be prepared at a temperature lower than 30C of the mixing and compaction temperature of the hot mixture, and ...

aspha-min is a synthetic zeolite additive for warm mix asphalt or low viscosity hot mix asphalt. For sustainable roads.
Jan 20, 2018 Currently, both commercial synthetic zeolites (e.g., Aspha-Min ) (Hossain et al., 2009) and natural zeolite (e.g. clinoptilolite) (Sengoz et al., 2013, Dubravsk and Mandula, 2015) are used as WMA additives. Zeolite additives can provide a viable tool for reducing mixing and compaction temperatures without affecting the basic engineering properties of asphalt mixtures.
Apr 30, 2014 The utilization of synthetic and natural zeolites improves the ability of asphalt pavements against permanent deformation and increases the rigidity of bituminous mixtures. The formation of crack in lower deformation levels as a result of repetitive loading is an indicator for brittle susceptibility level of a specimen.
Apr 12, 2019 Reports indicated that burner fuel savings with WMA typically range from 20 to 35 percent. These levels could be higher if burner tuning was completed to allow the burner to run at lower settings. Fuel savings could be higher (possibly 50 percent or more) with processes such as low-energy asphalt concrete (LEAB) and low-energy asphalt (LEA), in ...

They help by lowering the temperature during the manufacturing and laying of asphalt concrete, which results in less fossil fuel consumption and less carbon dioxide, aerosols, and vapors being released.
Embodiments are presented herein that provide a filler that is a combination of zeolite and hydrated lime. Addition of this filler to asphalt is more beneficial than addition of either zeolite or hydrated lime alone. The beneficial properties of zeolite include a controlled release of moisture that aids mixture workability and the ability of the asphalt to effectively coat the aggregate

This process uses a synthetic zeolite containing about 20 percent water of crystallization. Upon heating above the boiling point of water, a small amount of water is released, creating foaming. For batch plants, the zeolite material can be added to the pug-mill. For drum-plants, a feeder is needed to introduce the material into the binder stream.
