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.

The optimum asphalt content was determined as the asphalt content required to achieve 4 percent air voids at N des. The mixtures were then further analyzed to determine the volumetric properties of the stone mastic asphalt, resilient modulus and Marshall Properties (stability and flow).
These are Dense Graded asphalt, Stone Mastic Asphalt and Open Graded Asphalt. Stone mastic asphalt (SMA) is a stone-on-stone like skeletal structure of gap graded aggregate, bonded together by mastic, which actually is higher binder content, filler and fiber to reduce the binder drain.

Stone matrix asphalt (SMA) is a tough, stable, rut-resistant mixture that relies on stone-on-stone contact to provide strength and a rich mortar binder to provide durability . These objectives are usually achieved with a gap-graded aggregate coupled with fiber or polymer modified, and high asphalt content matrix .
515. MASTIC ASPHALT 515.1. Scope This work shall consist of constructing a single layer of mastic asphalt wearing course for road pavements and bridge decks. Mastic asphalt is an intimate homogeneous mixture of selected well-graded aggregates, filler and bitumen in such proportions as to yield a plastic and voidless mass, which
Muraya et al. found mastic had greater influence on the response of dense graded, high binder content mixtures than on stone-to-stone mixes, such as stone mastic and porous asphalt. Airport asphalts are usually specified to be dense graded with high binder contents and rely heavily on mastic performance to resist deformation  .
Crushed Waste Concrete in Stone Mastic Asphalt Mixtures. The magnitude 7.6 Chi-Chi Taiwan in 1999 and the magnitude 7.9 Sichuan China in 2008 earthquakes caused many building damage and collapse, and a large amount of waste concrete caused many environmental problems.
This new surface course specification, TS2010, comprises a range of Stone Mastic Asphalt mixtures that are based on German specifications and experience. The Stone Mastic Asphalt (SMA) mixtures will contain a gap-graded aggregate mix, polymer modified bitumen, and additives, including fibres. The newly-laid SMA will be treated
Stone Mastic Asphalt may be referred to by the acronym SMA. It is promoted primarily for use as a surfacing course with relatively high surface texture, low permeability and a high resistance to rutting. The coarse texture tends to reduce the generation of spray during rain periods.
implemented in European countries. The stone mastic asphalt is a gap graded mixture consisting of coarse aggregate, fine aggregate, stabilizers and binders. In the project work the main objective is to compare the results obtained by the fillers stone dust and coconut shell charcoal. The binder content has been varied from 4-6%. Binder of 60/70 .

The stone crusher is an indispensable equipment for the stone crushing line, Which can be used for primary, secondary and fine crushing of more than 200 kinds of rough stones such as granite, basalt, limestone, rock, concrete, aggregate, gravel, dolomite and quartz.
The question is – how to calculate the amount of asphalt? First of all we should take into account the type of bitumen-concrete mix. The largest amount – about 25.5kg per 1cm of thickness – will be for stone-mastic asphalt mix (SMAM).
Stone Mastix Asphalt German Solutions The arguments for SMA: 1. Skid resistance Aggregate Type / Design of surface texture 2. Eveneess / rutting strong aggregate structure 3. Noise - 2,0 dB (A) 4. Surface durability binder-rich and voidless mortar 5. Visibility reduced reflection and spray - Inner-city roads (difficult in laying manually)

In most cases the protective layer is a Mastic Asphalt layer. This layer also serves as a second waterproofing layer. The non-porous mastic asphalt is usually used for the protective layer of the bridge pavement. For various reasons, in some countries preference is given to a traditional asphalt layer as protection layer on concrete deck .
* The term ‘asphalt’ is used in this publication and unless accompanied by a descriptor for example “Asphalt Concrete” (AC), ‘Hot Rolled Asphalt’ (HRA) or ‘Stone Mastic Asphalt’ (SMA), is applied in its generic sense to refer to the range of mixtures used in the UK. Asphalts are used in games and sport areas in two ways:

KEYWORDS: Geopolymer, Stone mastic asphalt (SMA), Fly ash, Modified asphalt, Resilient modulus, Permanent deformation. INTRODUCTION According to the Malaysian Automotive Association (2012), statistics show that the total registered vehicles in Malaysia have increased over the past 32 years. The number of vehicles on roads has
Essentially, asphalt is a combination of aggregate (crushed rock and / or sand) and bitumen (derived from crude oil). Asphalt may also incorporate additives to improve performance (e.g. fibres, wax, polymers and pigments). Asphalt is commonly used in the construction of roads, pathways, car parks, driveways and play areas.
Stone mastic asphalt is a delicate balance be tween the mastic and the aggregate fraction requiring good quality aggregates, consistent grad ings and careful dosage of mineral fibres to avoid an .
Stone mastic asphalt (SMA), also called stone-matrix asphalt, was developed in Germany in the 1960s with the first SMA pavements being placed in 1968 near Kiel.It provides a deformation-resistant, durable surfacing material, suitable for heavily trafficked roads.

Stone Mastic Asphalt (SMA) means HMA consisting of a coarse aggregate skeleton and an asphalt binder rich mortar. The mixture has a gap graded aggregate skeleton with coarse aggregate stone-on-stone contact. Stone Mastic Asphalt (SMA) Mortar means a mixture of asphalt cement and any additives, hydrated lime,
STANDARD CONSTRUCTION SPECIFICATIONS FOR ASPHALT SURFACING DIVISION 40 SECTION 40.01 GENERAL Article 1.1 Scope of Work The Work covered by these Specifications consists of providing all plant, labor, equipment supplies, material, transportation, handling, and storage, and performing all operations
Stone matrix asphalt (SMA), sometimes called stone mastic asphalt, is a gap-graded HMA originally developed in Europe to maximize rutting resistance and durability. The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly .
This webinar recording provides an overview and history of SMA, followed by the design, production, and construction of SMA. We finish with three field examples from before 2012. The recording is .
Stone Mastic Asphalt has good rutting performance by heavy traffic and high volume roads at high temperatures. It also has better fatigue resistance and cracking at low temperatures, durability, permeability and sensitivity to moisture than Hot Mix Asphalts. Because of SMA has gap graded mixture, it has higher amount of voids in the mix.
Polished Stone Value specified by the contract document 4.3 Fine Aggregate Fine aggregate shall consist of particles of sand, crushed stone or crushed gravel or a mixture of these materials unless otherwise approved by Transit. The source material from which any crushed fine aggregate is produced shall comply with the crushing
Environmental and economic considerations have encouraged civil engineers to find ways to reuse recycled materials in new constructions. The current paper presents an experimental research on the possibility of utilizing recycled concrete aggregates (RCA) in stone mastic asphalt (SMA) and hot mix asphalt (HMA) mixtures.
As a filler normally crushed lime stone powder with calcium carbonate not less than 80% is used. But where acid resistance mastic is required, siliceous filler can be used.
