Qu’est-ce que le Stone Mastic Asphalt (SMA) ?<\/strong><\/strong><\/h1><\/div><\/div><\/div>\n<\/div><\/header>\n\n\n\n

<\/div>

Le Stone Mastic Asphalt (SMA)<\/strong> est un enrob\u00e9 bitumineux haute performance con\u00e7u pour r\u00e9sister aux charges de trafic les plus \u00e9lev\u00e9es. Il est compos\u00e9 d’une forte proportion de granulats grossiers, de filler min\u00e9ral, de bitume et de fibres de cellulose. Compar\u00e9 aux enrob\u00e9s bitumineux conventionnels, le SMA contient une quantit\u00e9 beaucoup plus importante de granulats grossiers. Les vides entre les granulats sont remplis par des granulats fins, du filler min\u00e9ral, du bitume et des fibres de cellulose<\/strong>, formant une structure pierre contre pierre offrant une excellente r\u00e9sistance \u00e0 l’orni\u00e9rage, une grande durabilit\u00e9 et une longue dur\u00e9e de vie.

D\u00e9velopp\u00e9 et utilis\u00e9 pour la premi\u00e8re fois \u00e0 Kiel, en Allemagne, en 1960<\/strong>, le Stone Mastic Asphalt est aujourd’hui largement utilis\u00e9 pour les autoroutes, les pistes d’a\u00e9roport, les ponts, les zones industrielles et les autres infrastructures routi\u00e8res soumises \u00e0 un trafic intense gr\u00e2ce \u00e0 ses performances m\u00e9caniques exceptionnelles.<\/p><\/div><\/div>\n\n\n\n

Propri\u00e9t\u00e9s et Applications du Stone Mastic Asphalt (SMA)<\/strong><\/strong><\/h2><\/div>
<\/div>

Avec l’augmentation du trafic lourd et les fortes charges exerc\u00e9es par les roues des avions lors des phases de d\u00e9collage et d’atterrissage, les chauss\u00e9es sont davantage expos\u00e9es \u00e0 la d\u00e9formation permanente (orni\u00e9rage). Le Stone Mastic Asphalt (SMA)<\/strong> est sp\u00e9cialement con\u00e7u pour r\u00e9sister \u00e0 ces contraintes verticales et horizontales \u00e9lev\u00e9es tout en offrant des performances exceptionnelles sans d\u00e9formation.<\/p><\/div><\/div>\n\n\n\n

Principales Propri\u00e9t\u00e9s et Avantages<\/h3><\/div>
<\/div>

Haute r\u00e9sistance \u00e0 l’orni\u00e9rage :<\/strong> Offre une excellente r\u00e9sistance aux d\u00e9formations permanentes et \u00e0 l’orni\u00e9rage sous un trafic intense.

Excellente adh\u00e9rence :<\/strong> Sa structure riche en granulats am\u00e9liore l’adh\u00e9rence des pneumatiques, garantissant une s\u00e9curit\u00e9 optimale m\u00eame sur chauss\u00e9e humide.

R\u00e9duction du bruit :<\/strong> L’association des granulats et des fibres de cellulose r\u00e9duit le bruit de roulement et am\u00e9liore le confort de conduite.

Longue dur\u00e9e de vie :<\/strong> Tr\u00e8s r\u00e9sistant au vieillissement, \u00e0 la fissuration et au trafic intensif, garantissant un rev\u00eatement durable et \u00e9conomique.<\/p><\/div><\/div>\n\n\n\n

Comment le Stone Mastic Asphalt (SMA) est-il fabriqu\u00e9 ?<\/strong><\/h2><\/div>
<\/div>

La fabrication du Stone Mastic Asphalt (SMA)<\/strong> exige une grande pr\u00e9cision, des \u00e9quipements sp\u00e9cialis\u00e9s et un processus de production rigoureusement contr\u00f4l\u00e9. Les principales \u00e9tapes de fabrication et les exigences techniques sont pr\u00e9sent\u00e9es ci-dessous.<\/p><\/div><\/div>\n\n\n\n

Int\u00e9gration des \u00e9quipements<\/h3><\/div>
<\/div>

Le Stone Mastic Asphalt (SMA)<\/strong> est produit dans une centrale d’enrobage<\/strong> moderne. Contrairement aux enrob\u00e9s conventionnels, sa fabrication n\u00e9cessite l’installation d’un syst\u00e8me de dosage des fibres de cellulose<\/strong> afin d’incorporer les fibres dans le m\u00e9lange et d’\u00e9viter l’\u00e9coulement du liant (binder drain-down).<\/p><\/div><\/div>\n\n\n\n

Syst\u00e8me de dosage des fibres de cellulose<\/strong><\/h3><\/div>
<\/div>

Les fibres de cellulose sont introduites dans le syst\u00e8me de dosage des fibres de cellulose<\/a><\/strong>, o\u00f9 elles sont dos\u00e9es avec pr\u00e9cision gr\u00e2ce \u00e0 une automatisation pilot\u00e9e par API (PLC). \u00c0 chaque cycle de production, la quantit\u00e9 requise de fibres est transport\u00e9e pneumatiquement puis inject\u00e9e directement dans le malaxeur de la centrale d’enrobage<\/strong>, garantissant un m\u00e9lange homog\u00e8ne et parfaitement stable.<\/p><\/div><\/div>\n\n\n\n

S\u00e9lection des granulats<\/strong><\/h3><\/div>
<\/div>

Pour obtenir la structure pierre contre pierre<\/strong> caract\u00e9ristique du Stone Mastic Asphalt (SMA)<\/strong>, il est indispensable d’utiliser des granulats de haute qualit\u00e9 pr\u00e9sentant une excellente r\u00e9sistance \u00e0 l’usure. Les granulats de basalte<\/strong>, les granulats riches en silice ainsi que d’autres pierres concass\u00e9es de qualit\u00e9 sup\u00e9rieure sont privil\u00e9gi\u00e9s afin d’am\u00e9liorer la durabilit\u00e9, la r\u00e9sistance \u00e0 l’orni\u00e9rage et la long\u00e9vit\u00e9 de la chauss\u00e9e.<\/p><\/div><\/div>\n\n\n\n

Chauffage et transfert du bitume<\/strong><\/strong><\/strong><\/h3><\/div>
<\/div>

Le liant provenant des r\u00e9servoirs de stockage de bitume<\/a><\/strong> est chauff\u00e9 \u00e0 une temp\u00e9rature optimale de 175 \u00b0C \u00e0 190 \u00b0C<\/strong>, puis pomp\u00e9 vers le malaxeur de la centrale d’enrobage<\/strong> afin d’assurer un enrobage homog\u00e8ne des granulats et une qualit\u00e9 constante du m\u00e9lange.<\/p><\/div><\/div>\n\n\n\n

Processus de malaxage<\/strong><\/strong><\/strong><\/h3><\/div>
<\/div>

Les granulats, le filler min\u00e9ral, le bitume et les fibres de cellulose sont m\u00e9lang\u00e9s \u00e0 une temp\u00e9rature optimale comprise entre 175 \u00b0C et 190 \u00b0C<\/strong>. Tous les composants sont malax\u00e9s de mani\u00e8re homog\u00e8ne pendant environ 65 \u00e0 80 secondes<\/strong>, produisant un m\u00e9lange de Stone Mastic Asphalt (SMA)<\/strong> offrant une excellente durabilit\u00e9, une grande r\u00e9sistance \u00e0 l’orni\u00e9rage et des performances \u00e9lev\u00e9es.<\/p><\/div><\/div>\n<\/div>\n<\/section>\n\n\n\n
