The performance of asphalt binders at high and low temperatures has an important role on the rutting and crackingresistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphaltphysical and mechanical properties and helps reducing environmental pollution. In this research, three unmodifiedand six CRM modified binders were teste...

The neutron is electrically neutral, but its substructure consists of charged quarks so it may have an internal charge distribution. In fact it is known to have a negative mean square charge radius (MSCR), the second moment of the radial charge density. In other words the neutron has a positive core and negative skin. In the first Born approximation the neutron MSCR can be simply related to the...

Minimum side-zone power to center-zone power ratio (MSCR) method is presented to estimate array errors of azimuth multichannel synthetic aperture radar (SAR). Spaceborne azimuth multichannel SAR is one of the most promising candidates for achieving high-resolution wide-swath imaging. However, array errors brought in by instrument influences and aperture position errors need to be compensated. M...

The MasterLife PAV110 Warm Mix Asphalt (WMA) additive’s rutting resistance in pure and Styrene-ButadieneStyrene (SBS)-modified binders was examined using MSCR testing. Multiple Stress Creep Recovery (MSCR) tests were conducted on seven binders. study’s findings indicated that the incorporation of WMA resulted an increase Jnr values both modified with SBS at stress levels 0.1 3.2 kPa. This find...

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...

The constant demand for high-performing and more reliable roads has led to an increasing use of complex bituminous binders such as polymer-modified binders, which become a widespread practice asphalt pavement. As result, specification testing have evolved better distinguish between quality materials. In recent years, focus been devoted evaluating the rutting resistance binders. multiple stress ...

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...

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...
