STONE MASTIC ASPHALT - Study Mafia

Stone Mastic Asphalt is characterised by its high stone content which forms a gap-graded skeleton-like stone structure. The voids of the structural matrix are filled with high viscosity bituminous mastic. The high stone content of at least 70% ensures stone-on-stone contact after compaction.

PDF Summary of Georgia's Experience with Stone Matrix Asphalt

Stone matrix asphalt (SMA) is a gap-graded mix which contains a high concentration of coarse aggregate, thereby maximizing stone-to-stone contact in the mix and providing an efficient network for load distribution. The coarse aggregate particles are held together by a rich matrix of mineral filler, fiber, and polymer in a thick asphalt film.

Advances in Bituminous Road Construction

Stone matrix asphalt (SMA) was developed in Germany in the mid 1960 and it has been used very successfully by many countries including US as a highly rut-resistant bituminous course, both for binder (intermediate) and wearing course for heavy traffic roads. Portland cement, fly ash, and lime, are added to obtain ail improved base. The four

NCAT Report 17-03R EFFECT OF FLAT AND ELONGATED

The importance of this study is driven by asphalt mixture economics since the in-place cost of stone matrix asphalt (SMA) mixtures ranges from 20 to 80% higher than conventional dense-graded mixes. The production of SMA aggregate alone is believed to cost approximately twice that of conventional aggregate production.

Stone Matrix Asphalt - Texas Asphalt Pavement Association

Stone Matrix Asphalt or SMA mixtures are typically used as a surface mix or intermediate layer in the pavement structure on high volume (or high demand) roadways. The standard SMA mixture contains PG 76-22 and fibers, and is recommended for the vast majority of applications where SMA is used or desired and when placed as an overlay on a

Performance Evaluation of Bituminous Paving Mixes

On the other hand, stone matrix asphalt is a gap-graded mix with 75-80% coarse aggregate, 20-25% fine aggregate, 9-13% filler, and higher amount of bitumen content (Bose et al. 2006). Due to rapid the growth of different coal-based thermal power plants, the production of fly ash as a waste by-product is sharply increasing day by day in India.
