Performance and Aging Characteristics of Hot Mixture Asphalt with Crumb Rubber and Warm Mix Asphalt Additives
(ASCE, 8/1/2020 1)In this study, the mixes prepared using crumb rubber (CR) and binders with warm mix additives were aged through various aging methods (1, 2, 3, and 4 weeks at 60°C in the laboratory; 2, 4, 6, 8, 10, and 12 months under ... -
Three-Stage Evolution of Air Voids and Deformation of Porous-Asphalt Mixtures in High-Temperature Permanent Deformation
(ASCE, 9/1/2020 1)The objective of this paper was to investigate the evolution of air voids (AV) and deformation and the failure mechanism of porous asphalt (PA) mixtures under high temperatures. An advanced repeated loading permanent ... -
Minimal Drilling Technique to Measure Chloride-Penetration Depth and Carbonation Depth in Concrete
(ASCE, 9/1/2020 1)A method was investigated to determine concrete durability by measuring the carbonation depth and chloride ion (Cl−) penetration depth. Under the proposed method, a 1- or 2-mm-diameter hole was drilled into a concrete ... -
Durability Assessment of Soil-Pozzolan-Lime Blends through Ultrasonic-Pulse Velocity Test
(ASCE, 8/1/2020 1)The improvement of soils that are not suitable for a particular purpose through techniques that combine densification and the incorporation of portland cement have been extensively done for decades in spite of the poor ... -
Effects of Curing Method on Properties and Salt-Scaling Resistance of Concrete under Lab Testing
(ASCE, 8/1/2020 1)This paper presents a study of the effect of curing on the salt-scaling resistance of concrete containing supplementary cementitious materials (SCMs) under lab conditions. Two curing methods were examined: moist curing and ... -
