How is Foundry Sand used in Hot Mix Asphalt? Foundry sand has successfully been used as a fine aggregate substitute in HMA for many years on both public and private sector HMA projects. HMA producers can often save money by sourcing foundry sands instead of virgin sands. Up to 30% of the total aggregate mix can be replaced with foundry sand.

Characterisation of Foundry Sand Waste Material for Road,
Foundry sand is an industrial waste material generated from the foundry industries spreded all over the country. It is a natural sand which is used as a molding material in the ferrous and nonferrous metal casting industries. This sand is typically recycled and reused through many production cycles.
Ladle furnace slag in asphalt mixes - ScienceDirect
30-09-2016· Ladle Furnace Slag (LFS) may be used in substitution of fine aggregate (2–0.063 mm), and filler (<0.063 mm) in bituminous mixtures, considering its suitable particle size and hydraulic properties. From among the range of bituminous mixtures, this research is conducted on Porous Asphalt mixes (PA).

Ferrous foundry slag is also used as coarse aggregate in HMA. How does Hot Mix Asphalt perform using Foundry Sand? In general, tests on mixtures of HMA containing foundry sand have performed as well or better than mixtures made with natural sands.
Slag - Jernkontoret
31-05-2021· Slag asphalt achieves better durability, shear strength (dynamic torsional stiffness and tensile strength) and stability (bearing capacity) compared with traditional asphalt. These properties make slag asphalt a good alternative in roundabouts, in braking and starting distances, or heavily used traffic routes.

George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016 10.4.3.6 Cold mix-foamed asphalt EAF steel slag, foundry sand , bottom ash, and reclaimed asphalt pavement (RAP) meeting physical and mechanical properties were mixed in variable proportions that satisfied the technical specifications for cold mixtures.
Environmental and Geotechnical Assessment of the Steel,
30-07-2015· The application of steel slag in asphalt concrete also gives good performance [21,22]; however, the use of steel slag as a construction material has been a problem, because free CaO abundant in steel slag in contact with water transforms into Ca(OH) 2 . Moreover, steel slag could be subjected to various treatments.
Use of ladle furnace slag as filler in hot asphalt,
10-02-2018· Ladle furnace slag (LFS) mainly consists of quicklime (about 50%) and silica (20%). 0.25-mm sifted and hydrated LFS guarantees the best asphalt concrete (AC) performance. AC including sieved and hydrated LFS has improved stiffness and strength. AC including sieved and hydrated LFS has an excellent resistance to fatigue.
State-of-the-Art Review on Sustainability in Geotechnical,
22-11-2021· Recent studies show that in pavement construction, there is significant possibility of reusing waste materials like asphalt concrete, bituminous waste, crushed concrete aggregate, glass aggregates, roofing scrap, foundry sand, nonferrous slag, steel slag, blast-furnace slag, coal bottom ash, coal boiler slag, scrap rubber tire chips, municipal solid waste incinerator ash

Utilization of Industrial Wastes in Road Construction: A,
The foundry sand was used as the embankment fill material, an aggregate alternative in asphalt concrete and the aggregate to controlled low strength material [11]. In hot mix asphalt pavements, the foundry sand is used as an alternative material to fine aggregate. It shows a satisfactory performance [12].
