Investigating the Crack Initiation and Propagation of Asphalt Binder in Linear Amplitude Sweep Test
(ASCE, 12/1/2020 )The linear amplitude sweep (LAS) test has been widely accepted for estimating the fatigue resistance of asphalt binders in the last 10 years. This paper proposes a fracture mechanics–based analytical approach for crack ... -
NMR Study on the Pore Structure Development of Cement Paste with Bleeding during Hydration
(ASCE, 12/1/2020 )Previous studies focused on the determination and simulation of the bleeding extent of fresh cement paste and provided objective conclusions. However, few studies exist on the influence of bleeding on the final structure ... -
Parametric Analysis of the Drainage Performance of Porous Asphalt Pavement Based on a 3D FEM Method
(ASCE, 12/1/2020 )Porous asphalt pavement can reduce noise and improve road safety and driving comfort on rainy days. The seepage model derived from the one-way gradient flow theory cannot truly reflect the seepage process of rainwater ... -
Reliability Assessment of Concrete under Chloride Penetration and Fatigue Loading Based on Copula Function
(ASCE, 12/1/2020 )The reliability of concrete in complex environments is the basis for improving the reliability of concrete structures. A concrete reliability assessment based on multiple degradation factor is proposed. First, chloride ... -
Crude Urease Extract for Biocementation
(ASCE, 12/1/2020 )A crude extract from jack beans (Canavalia gladiata) is demonstrated to be an effective source of urease enzyme for biocementation via enzyme-induced carbonate precipitation (EICP). Test tube tests of crude and purified ... -
Modification Mechanism of Using Waste Wood–Based Bio-Oil to Modify Petroleum Asphalt
