Aggregates used in SMA must be of high quality – well shaped, resistant to crushing and of suitable polish resistance. Binders used in SMA include: Class 320 bitumen - used in many general applications.Multigrade binder - used to provide enhanced performance at higher traffic levels.Polymer modified binder - … Visa mer 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 … Visa mer SMA is mixed and placed in the same plant as that used with conventional hot mix. In batch plants, the fibre additive is added direct to the pugmill using individually wrapped … Visa mer • SMA provides a textured, durable, and rut resistant wearing course. • The surface texture characteristics of SMA are similar to Open graded asphalt (OGA) so that the noise generated by traffic is lower than that on DGA but equal to or slightly higher than OGA. Visa mer • Permeable paving • Plastic armour • TexSys - Texas Expert System for the selection of Hot-Mix Asphalt (HMA) based on TxDOT (2004). Visa mer The primary difference in placing SMA, compared to DGA is in compaction procedures. Multi-tyred rollers are not used due to the possible working of binder-rich material to the surface of the asphalt and consequent flushing and pick-up. Trafficking of the … Visa mer • Increased material cost associated with higher asphalt binder and filler contents, and fibre additive. • Increased mixing time and time taken to add extra filler, may result in reduced productivity. • Possible delays in opening to traffic as the SMA mix should be cooled to … Visa mer WebbSMA 28 bin PmB 40/100 – Stone Mastic Asphalt – SMA Binder Course PSV ≥ 45.
