Abstract: This paper is intended to verify the concern expressed by researchers that stiff asphalt-mineral filler mastics may lead to the cracking of flexible pavements in the brittle-ductile region. Test results obtained from the ...

Abstract: There has been an increasing awareness of the role of zero shear viscosity (ZSV) of bituminous binders as performance indicators of resistance to permanent deformation of asphalt mixtures because in some cases the conventional ...

Abstract: The styrene-butadiene-styrene (SBS) triblock copolymer was used to modify the asphalt binder. The morphology and engineering properties of the binders were investigated using transmission electron microscopy (TEM), rotational ...

Abstract: The purpose of this study was to evaluate the pavement distress associated with moisture and cracks. A feedback-controlled test was developed to generate a crack with a controlled width in asphalt concrete specimens. Three ...

Abstract: Fatigue cracking is considered to be the primary failure mechanism that occurs at ambient temperatures in an asphalt pavement. The bituminous binder plays an important role in this failure mechanism, because fatigue cracking ...

Abstract: Porous asphalt concrete (PAC) is a particular type of asphalt mixture that has a high content of air voids that is generated because of an open-graded design. The objective of the study is to investigate the effect of the ...

Abstract: Dramatic increases in the number and weight of vehicles have resulted in severe rutting on highways in Taiwan. The Taiwan Area National Freeway Bureau constructed an in-service test road in 1996 to investigate the effect ...

Abstract: This paper is aimed at estimating the time available for compaction of a hot-mix asphalt mixture during night construction. Laboratory tests were conducted on dense-graded and porous asphalt (PA) mixtures to evaluate their ...

Abstract: The paper is aimed at investigating the dielectric response of the dense-graded hot-mix asphalt mixture (HMA) using an open-ended coaxial probe technique over a wide frequency range. The effects of asphalt content, air ...

Abstract: For both environmental and financial reasons, the use of reclaimed asphalt pavements (RAP) needs to be maximized. In this study, rejuvenators and soft asphalt cements were used as recycling agents. Aged binders recovered ...
