“…Dynamic mechanical analysis has been used in the past to investigate the viscoelastic properties of bituminous concretes. Dynamic modulus test is one of the most common procedures for determining the dynamic modulus of bituminous mixture [ 48 , 49 ]. In this paper, the dynamic modulus experiment was carried out for three replicate specimens at different experimental conditions, the detailed test program is shown in Table 4 and Table 5 .…”

The purpose of this paper is to promote the application of nano-TiO2/CaCO3 in bituminous materials and present an experimental characterization of viscoelastic behaviors of bitumen and bituminous mixture modified by nano-TiO2/CaCO3. In this work, a series of viscoelastic behavior characterization tests were conducted, including dynamic shear rheometer (DSR) test for bitumen, uniaxial static compression creep test and dynamic modulus test for bituminous mixture. Moreover, various viscoelastic models with clear physical meanings were used to evaluate the influence of nano-TiO2/CaCO3 on the macroscopic performance of bitumen and bituminous mixture. The results show that bitumen and its mixtures are time-temperature dependent. The Christensen-Anderson-Marasteanu (CAM) model of frequency sweep based on DSR test indicated that adding nano-TiO2/CaCO3 can effectively capture the sensitivity of temperature. In addition, the incorporation of nano-TiO2/CaCO3 in bituminous mixture can significantly enhance the high-temperature anti-rutting, and slightly improve the low-temperature anti-cracking as well. At the same time, the modified Burgers model can accurately describe the viscoelastic behavior of bituminous mixtures in the first two creep stages, reflecting the consolidation effect of bituminous mixture. Also, the generalized Sigmoidal model can accurately grasp the characteristics of the relationship between dynamic modulus and reduced frequency and achieve good prediction effects in a wider frequency range.

“…Feng et al studied the effect of moisture content on the strength of the waterproof adhesive layer. e results showed that the shear strength of the waterproof bonding layer increased with the decrease of moisture content [9,10]. In addition, the performance of the waterproof adhesive layer is not only related to itself but also related to the cement concrete layer and asphalt mixture layer bonded with it.…”

The weak connection performances between the waterproof adhesive layer, the bridge deck, and asphalt pavement are important factors that cause the bridge deck slippage and upheaval and affect the safety and durability of the bridge. In this paper, styrene-butadiene-styrene- (SBS-) modified asphalt, SBS-emulsified asphalt, rubber-modified asphalt, and AMP-100 waterproof materials are selected to study the performance of the bridge deck waterproof adhesive layer in the seasonal frozen region. The shear strength and bond strength of the four waterproof adhesive materials were obtained through the shear test and pull-out test of the composite specimens composed of four kinds of adhesive materials, diatomite rubber-particle asphalt mixture, and concrete bridge deck at different dosages and temperatures. According to the priority analysis of the factors including cost, construction difficulty, and environmental protection for the four kinds of materials by using analytic hierarchy process (AHP), SBS-modified asphalt is obtained as the most suitable waterproof adhesive layer of diatomite rubber particle asphalt mixture bridge deck in seasonal frozen region.

Nanomaterials have a great potential for enhancing the performance of base asphalt binder. This study aims to promote the application of nano-TiO2/CaCO3 in bitumen and presents a study on rheological properties for TiO2/CaCO3 nanoparticle-bitumen. In this study, a series of laboratory experiments have been performed for bitumen with different nano-TiO2/CaCO3 dosages. Nano-TiO2/CaCO3-modified bitumen with optimum dosage was prepared for viscosity, dynamic shear rheometer (DSR), and beam bending rheometer (BBR) for assessing temperature sensitivity of bitumen, and the low-medium-high-temperature performances were analyzed for TiO2/CaCO3 nanoparticle-bitumen as well. Results show that bituminous mechanical properties were enhanced by TiO2/CaCO3, and based on the overall desirability analysis of various conventional tests, the reasonable dosage of nano-TiO2/CaCO3 was recommended as 5% by weight of base bitumen. Adding nano-TiO2/CaCO3 was beneficial to improve the viscosity and reduce the temperature sensitivity of bitumen. The capacities of bituminous rutting resistance as well as medium-temperature fatigue resistance were enhanced by the addition of nano-TiO2/CaCO3. However, BBR test shows that bituminous anticracking is reduced slightly. On this basis, the Burgers model is selected for clarifying the decrease in anticracking performance; that is, nano-TiO2/CaCO3 increased the stiffness modulus while increasing the viscosity of bitumen.
