Abstract Different microstructures of the same polymer-modified bitumen (PMB) were obtained by subjecting modified with styrene-butadiene-styrene (SBS) copolymer to isothermal annealing at various temperatures. The effects morphology on rheological properties SBS-modified investigated within high-temperature range. PMB quantitatively evaluated using image analysis. A dynamic shear rheometer was...

In recent decades, the application of modified bitumens has experienced tremendous growth. However, due to varying modification mechanism different modifiers, creep and recovery properties bitumen have not been comprehensively understood. This study aims evaluate several representative using multi-stress (MSCR) test. The MSCR test can highlight unique delayed elasticity it uses a high stress le...

Warm mixtures are an essential alternative for paving as they minimize costs and environmental impacts, their performance is similar to hot mixtures. This research evaluated the effect of adding linseed oil obtained from Linum usitatissimum in contents 1, 2, 3, 4, 5, 6% by weight on physical rheological properties asphalt binder. The binder was through tests penetration, softening point, rotati...

The performance of an asphalt mixture is significantly affected by the properties its mortar, which consists binder, mineral fillers, fine aggregates and air voids. aim this work was to evaluate correlations between high-temperature rheological corresponding mortar. multisequence repeated loading (MSRL) test used estimate mixture. Six different gradations, AC-13, SMA-13, SUP-13, AC-20, SUP-20 A...

The high-temperature rheological properties of emulsified asphalt mastics have a significant impact on the service performance cold recycled mixtures with emulsions. In this paper, dynamic shear (DSR) test and multiple stress creep recovery (MSCR) are carried out to analyze influence tunneling coal gangue powder (TCGP), portland cement (PC), limestone (LP), four kinds filler binder ratio (F/B) ...

The preparation method of SBS-modified asphalt has a direct effect on its overall performance. Currently, the optimal process is usually determined by conventional performance properties, such as softening point, ductility, and penetration, which may deviate from practical field This study aims to investigate influence different methods microstructure based fluorescence microscopy testing, mult...

Asphalt mastic, which consists of an asphalt binder and a mineral filler, provides critical adhesion viscoelasticity to mixture. The rheological response the mastic is mainly derived from its binder. In this study, simple laboratory test method proposed estimate relationship mastic. Two modified binders (3.5% 4.0% styrene–butadiene–styrene (SBS) by mass) were blended with limestone filler at si...
