“…As for foaming technologies, most of the suppliers advise the use of antis tripping additives as summarized in Table 1. However there is a precaution that the lower temperatures used for WMA production may reduce the effectiveness of any chemical antis tripping additives additionally used in the process (11). This should be considered when choosing a specific anti-stripping product.…”

“…Awanti et al 2006, (11) studied influences of modified marshal compaction techniques o engineering properties of polymer modified and neat bituminous concrete mixes and reported about the various laboratory investigations carried out on two types of polymer modified bituminous concrete mixes with SBS copolymer and SBR and neat bituminous concrete mix 80/100 bitumen and studied the effects of adopting modified Marshall compaction technique on engineering properties of optimum binder content and Marshall parameters. Marshall Test results indicated higher stability, higher flow, higher unit weight lower air voids and lower optimum binder content for all mixes compacted with modified Marshall Hammer when compared to standard Marshall Compaction.…”

“…Awanti et al 2006 (11) in his research on fatigue behavior of polymer modified and neat bituminous mixes using modified Marshall specimens, from their experimental work and subsequent material used, characterized the neat and polymer modified bituminous binder and specifically concluded that softening point and viscosity values found to be higher by 16 and 98% for PMB-SBS when compared to neat bitumen. Elastic recovery showed higher flexibility and higher deformation resistance of pmb compared to pmb-sbr mixing and compaction temperatures for pmb binders were 150-170°C respectively, for neat bitumen these values were 150-138°C respectively.…”

With increasing concerns of global warming and increasing exhausation of gases, the asphalt industry looking for alternative for hot mix asphalt (HMA). Warm mix asphalt (WMA) is a fast emerging new technology which has a potential of revolutionalizing the production of asphalt mixtures. WMA technology allows the mixing, lay down and compaction of asphalt mixes at significantly lower temperatures compared to hot mix asphalt (HMA). The technology can reduce production temperatures by as much as 30 percent. Asphalt mixes are generally produced at 150°C or greater temperatures depending mainly on type of binder used. WMA mixes can be produced at temperatures of about 120°C or lower. In this study an attempt has been made to compare HMA (VG-30 and WMA (SBS-PMB-40) with organic additives (Zycotherm, Sasobit and Evotherm) with various dosages on Marshall properties for Dense Bituminous Macadam (DBM), Grade-2. the adopted mixing temperatures for HMA was 155°C, 130°C, and 120°C and mixing temperature for WMA was 130°C and 120°C. The laboratory study concludes that stability and Marshall properties for WMA mix were improved by addition of additives.

“…Adding polyethylene increased mixture workability and efficiency of compaction for modified mixes [9]. Awanti et al showed that the static indirect strength values for SBS modified asphalt concrete were higher in order of 49-101% when compared to conventional asphalt mixtures in the temperature range of 15-40°C [10]. H. M. Rasel et al examined the properties of bitumen grade 80/100 mixed with PVC (2.5% to 20 % by weight of bitumen) at optimum bitumen content and checked the design criteria of bituminous mixes using this bitumen-PVC binder.…”

“…Sun et al [27] found that reactive blending of SBS and asphalt can improve the hot storage stability, rheological properties, elasticity, and deformation resistance of modified asphalt. The limitations for SBS modified asphalt lie in its lower workability, higher production cost, and being easy to aging [28,29]. Therefore, it is crucial to have some other waste materials to partially substitute for SBS in modified asphalt.…”

Asphalt mixture is susceptible to moisture damage under the effect of freeze-thaw (F-T) cycles. In this paper, crumb rubber (CR) was used to modify stone mastic asphalt (SMA) and the effects of diatomite and styrene butadiene styrene (SBS) on antifreezing performances of crumb rubber modified SMA (CRSMA) were investigated. Regression analysis and modified grey model (MGM) were used to construct the prediction models for properties of modified mixtures. CRSMA, CR and diatomite modified SMA (CRDSMA), and CR and SBS modified SMA (CRSSMA) were prepared in laboratory, respectively. Process of F-T cycles was designed. Air void, indirect tensile strength (ITS), and indirect tensile stiffness modulus (ITSM) were measured to evaluate the antifreezing performances of CRSMA, CRDSMA, and CRSSMA. Results indicate that air voids increase with the increasing of F-T cycles. ITS and ITSM all decrease with the increasing of F-T cycles. The addition of diatomite and SBS can reduce the air void and improve the ITS and ITSM of CRSMA. CRSSMA presents the lowest air void, highest tensile strength, and largest stiffness modulus, which reveals that CRSSMA has the best F-T resistance among three different kinds of mixtures. Moreover, MGM (1, 2) models present more favorable accuracy in prediction of air void and ITS compared with regression ones.
