Stone mastic asphalt - Wikipedia
WEBStone 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. [1] It provides a deformation-resistant, durable surfacing material, suitable for heavily trafficked roads.
Stone Matrix Asphalt - Pavement Interactive
WEBStone matrix asphalt (SMA) is a gap-graded HMA (Figure 1) that is designed to maximize deformation (rutting) resistance and durability by using a structural basis of stone-on-stone contact (Figures 2-6).
WEBUse of SMA, including full-depth perpetual SMA, is recommended in any high loading condition pavement where long term rut resistance and durability are desired. Summary:
Mix Types - Pavement Interactive
WEBStone 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.
WEBSMA — otherwise known as Split Mastic Asphalt/Stone Mastic Asphalt/Stone Matrix Asphalt — was developed in Germany in the late 1960s. The original impetus was to develop a mix with better resistance to studded tires. Simply stated, SMA is a gapgraded mix designed to - direct stone on stone achieve contact.
WEBStone Matrix Asphalt (SMA) is a tough, stable, rut-resistant mixture. The SMA design concept 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 and/or polymer-modified, high asphalt content matrix.
WEBSMA: durable and rut-resistant gap-graded asphalt mix. Stone-on-stone contact to offer strength. Rich mortar binder to provide durability. First introduced into the United States in early 1990s. Commonly used as a premium asphalt mix to enhance field performance and extend life span of asphalt pavements and overlays.
Stone Mastic Asphalt - an overview | ScienceDirect Topics
WEBStone Mastic Asphalt (SMA) is a gap-graded skeleton dense asphalt mixture with voids filled with a considerable amount of asphalt binder, stabilizer and finer aggregate, which results in a low air void content (3%–8%) (Vázquez et al., 2019).
IAPA :: Stone Matrix Asphalt
WEBStone-matrix asphalt (SMA) is a gap-graded asphalt pavement designed to improve rut resistance and durability through the use of a stable stone-on-stone skeleton held together by a rich mixture of asphalt cement, along with stabilizing agents such as fibers and/or asphalt modifiers.
