RISEvaluation of Asphalt Mixtures’ Moisture Sensitivity by Dynamic Creep Test
Publisher: American Society of Civil Engineers
Abstract: A closer look at a number of researches carried out on the stripping potential of asphalt mixtures shows that there is no global agreement on a comprehensive procedure for evaluation of the moisture sensitivity of these ...
Commuters' Preference to Walk: Developing a Structural Equation Model Considering Current Amount of Walking and Subjective and Environmental Factors
Publisher: ASCE
Abstract: One important research question related to walking for transportation is whether people like to walk more or not. Past research on walking-related travel behavior has mainly considered objective measures of walking, ...
Fractional Viscoelastic Study of Low-Temperature Characteristics of Biomodified Asphalt Binders
Publisher: American Society of Civil Engineers
Sustainable Induction-Heatable Cold Patching Using Microwave and Reclaimed Asphalt Pavement
Publisher: ASCE
Abstract: Patching is a common pavement treatment, and it is implemented using hot and cold process patching. Hot process patching is not an efficient implementation method because keeping asphalt temperature in long hauls is ...

Investigation on the Effect of Ethylene Bis(Stearamide) and Polyphosphoric Acid Modification of Bitumen for Paving Applications
Publisher: ASCE
Abstract: In this study, the mutual effect of polyphosphoric acid (PPA) and ethylene bis(stearamide) (EBS) modification was examined on the high and low service temperatures and viscosity of a performance grade (PG) 58-22 asphalt ...
Investigating the Effects of Loading Frequency and Temperature on Moisture Sensitivity of SBS-Modified Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: The main objective of this study was to investigate the effects of loading frequency and temperature on the moisture sensitivity of dense-graded polymer-modified asphalt mixtures using the creep curves derived from the ...
Modeling the Primary and Secondary Regions of Creep Curves for SBS-Modified Asphalt Mixtures under Dry and Wet Conditions
Publisher: American Society of Civil Engineers
Abstract: This study was conducted to model the primary and the secondary regions of creep curves, derived from dynamic creep tests, for dense graded polymer modified asphalt mixtures under different moisture conditions. For this ...
Mechanical Behavior of Polymer-Modified Bituminous Mastics. II: Numerical Approach
Publisher: American Society of Civil Engineers
Abstract: After a comprehensive experimental program on asphalt mastic modified with styrene-butadiene-styrene (SBS) and polyphosphoric acid (PPA) with two filling ratios of 18% and 35%, in this paper, a biphasic finite-element ...
