“…Laboratory research indicates that using carbon fibers improves the resistance of SMAs to permanent deformations and enhances the load-bearing capacity of the surface layer [6]. The addition of glass fiber improves the properties of SMA mixtures by reducing instability, increasing flow value, and decreasing voids in the mix [7]. Furthermore, adding fiber enhances fatigue properties by increasing resistance to cracking and permanent deformation in bituminous mixtures [6].…”

This study examines the role of fibers formed from para-aramid and micropolyethylene in enhancing the performance of stone mastic asphalt (SMA) mixtures against permanent defor- mation. The use of SMA mixtures has the potential to mitigate permanent deformation and plasticity. Marshall tests, static creep tests, fatigue tests, and wheel track tests were conduct- ed on samples prepared using the modified Marshall design method to achieve the research objectives. According to the test results, Samples containing 1.5% of the fiber mixture's total weight exhibited greater strength than other samples. Additionally, these samples demonstrat- ed the most minor displacement against rutting among all prepared samples. Based on these findings, incorporating fibers containing Para-aramid and Micro-polyolefin in SMA mixtures can enhance the performance of this type of mixture against permanent deformations.

“…Numerous studies have revealed that some compositions of these waste materials can successfully be reused and recycled in pavement structures. In literature, various waste materials were employed as filler material in asphalt mixtures, including pumice dust [6,7], coal dust [8], fly ash [9][10][11][12][13], marble waste dust [14,15], sewage sludge ash [16], and rice husk ash [17,18].…”

A significant issue that researchers have been addressing recently is the recycling of various waste materials from different industries. Annually, millions of tons of waste are released. Pollution and safe, cost-effective disposal are critical issues with these waste materials. This study aims to investigate usability of concrete waste (COW) and ceramic waste (CEW) as filler material in Hot Mix Asphalt (HMA). Firstly, in this direction, a series of tests were conducted to determine the optimum bitumen content. Five different bitumen contents (i.e., 4.5%, 5%, 5.5%, 6%, and 6.5%) were used to prepare asphalt concrete samples. The Marshall Stability (MS) test was then performed on the prepared samples using various filler ratios, including limestone (LS), concrete waste (COW), and/or ceramic waste (CEW). Selecting the series of asphalt with 4% filler that has provided the maximum stability, COW or CEW was replaced with LS filler at rates of 25%, 50%, 75%, and 100%. Consequently, the use of COW or CEW as a mineral filler in HMA was found to be suitable.

“…Stone mastic asphalt mixes are sensitive to drain down because they contain more bitumen than hot mix asphalts. For this reason, stabilizers are used to prevent the bitumen material from drain down during the storage-transportation-paving-compacting processes (Aslan et al 2018). Fibers are the one of the stabilizers frequently used in SMA (NCHRP Synthesis 475, 2015).…”

Stone mastic asphalt (SMA) pavements were developed to prevent rutting, abrasion, and various pavement deteriorations and to increase the life of the superstructure. They certainly stand out with their high grain contact, stone-stone interlocking ability, and high bitumen ratio on heavy-traffic roads with heavy axle loads. This study aimed to investigate the effects of basalt fiber in different sizes, partly cellulose, and partly basalt fiber addition, on the drain down of the performance of bitumen and the changes in rutting performance as additives to stone mastic asphalt pavements. To determine the absorption performance of bitumen fiber additives, 19 mixtures were pre-pared and the Schellenberger drain down test was carried out. The results, including the witness mixture, showed that the Schellenberger test result was below the value specified in the motorway technical specification by a maximum of 0.3%. For the Hamburg wheel tracking test (HWTT) additive and witness mixtures were prepared at optimum bitumen ratios using a gyratory compactor. HWTT was applied to the mixtures numbered 1, 4, 10 and 14, which have the best the Schellenberger drain down performance, and the witness sample. As a result of the experiments, the highest rutting deformation was measured at the samples using 12mm basalt fiber at the rate of 0.2%. The lowest rut deformation was measured in samples containing 12mm basalt fiber at the rate of 0,3% and cellulose fiber at the rate of 0.2%. It was determined that the combined use of cellulose and basalt fiber mixture improved the resistance against rutting by 37%. As a result of the HWTT, it was determined that stone mastic asphalt mixtures with basalt and cellulose fiber additives were more resistant to rutting than the witness and basalt-only mixtures.
