RISInvestigation of the Hydraulic Properties of Pervious Pavement Mixtures: Characterization of Darcy and Non-Darcy Flow Based on Pore Microstructures
Publisher: ASCE
Abstract: The significance of water flow behavior as one of the main properties of pervious pavements has long been recognized. However, the quantification of flow characteristics and the relationship to complex pore microstructures ...
Use of Polyurethane Precursor–Based Modifier as an Eco-Friendly Approach to Improve Performance of Asphalt
Publisher: ASCE
Abstract: With the rapid growth of traffic demands, the use of liquid chemical material instead of traditional modifier to prepare high-performance modified asphalt demonstrates dual values in environmental protection and performance ...
Effects of Bitumen Origins and Filler Types on the Micromechanics Prediction of Complex Modulus of Asphalt Mastics Considering Interparticle Interactions
Publisher: ASCE
Abstract: Asphalt mastic is a binary composite in which the bitumen matrix is embedded with filler particles. By taking interparticle interactions and the effects of bitumen origins and filler types into account, this research seeks ...
Physicochemical Rejuvenation of Aged Styrene-Butadiene-Styrene-Modified Bitumen through Joint Use of Polyurethane Prepolymer and Tall Oil for Maintaining High-Temperature Property
Publisher: ASCE
Abstract: Conventional rejuvenation techniques, such as adding oil-based substances, are proved very effective to improve some properties of aged styrene-butadiene-styrene modified asphalt (SBSMA), including low-temperature cracking ...
Dynamic Response of Fully Permeable Pavements: Development of Pore Pressures under Different Modes of Loading
Publisher: ASCE
Abstract: Permeable pavements are widely recognized as an effective way to improve the environmental and ecological aspects of conventional dense pavements. Based on traditional pavement materials, permeable pavements are often ...
Comparison of the Polishing Resistances of Concrete Pavement Surface Textures Prepared with Different Technologies Using the Aachen Polishing Machine
Publisher: ASCE
Abstract: Due to greater durability and lower maintenance costs, concrete pavements are more competitive than asphalt pavements in areas where rigid pavements are required. To ensure the surface skid resistance of concrete pavement ...
Influence of Different Fillers on Mechanical Properties of Porous Asphalt Mixtures Using Microstructural Finite-Element Analysis
Publisher: ASCE
Abstract: Currently, recovering the natural hydrological cycle and lowering urban flood risk are global challenges. A permeable pavement with void-rich pavement materials, such as porous asphalt (PA), is one feasible and effective ...
Study on the Water Stability of Polyurethane Concrete from Perspective of Polyurethane-Aggregate Interface
Publisher: ASCE
Abstract: Since the conventional asphalt concrete will release many harmful gases including greenhouse gas in the construction process and it is prone to early diseases leading to long-term performance deficiencies, in recent years, ...
Skid Resistance Performance Analysis and Driving Safety Evaluation in the Full Life Cycle of Asphalt Pavement
Publisher: American Society of Civil Engineers
Abstract: Skid resistance of pavement plays a vital role in transportation safety, and it continuously deteriorates because the pavement was exposed to traffic and environmental loadings. Although the evaluation law of asphalt ...
Performance Evaluation of Carboxylated Styrene–Butadiene Latex in Bitumen and in Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Restricted by the harsh environmental conditions in cold regions, the construction of polymer-modified asphalt pavement in these areas is usually a process of high emissions of toxic and harmful gas and large energy ...
