RISAnalysis of Aggregate Gradation and Packing for Easy Estimation of Hot-Mix-Asphalt Voids in Mineral Aggregate
Publisher: American Society of Civil Engineers
Abstract: The voids in mineral aggregate (VMA) design parameter is one of the most important in the current Superpave mix design procedure that links hot-mix-asphalt (HMA) mix properties to field performance. The success of achieving ...
Case Study: Ten Year Field Performance Evaluation of Flexible Base Asphalt Pavement Design in Heavy Load Condition
Publisher: ASCE
Abstract: This research aims to evaluate the performance of flexible base asphalt pavement compared with traditional semirigid base asphalt pavement in practical application in central China under heavy load conditions. Four different ...
Effect of Aggregate Properties on Long-Term Skid Resistance of Asphalt Mixture
Publisher: ASCE
Abstract: This research aimed to evaluate the impact of aggregate characteristics on the skid resistance of pavement. Firstly, the mineral composition, wear-resistance property, angularity, and texture of five types of aggregates ...
Gradation Segregation Characteristic and Its Impact on Performance of Asphalt Mixture
Publisher: ASCE
Abstract: The aggregate segregation during construction has a significant impact on the performance of asphalt pavement; however, the segregation evaluation parameters selected by different researchers varied a lot. Also, standard ...
Effect of Coarse Aggregate Characteristics on Skid Resistance Deterioration of the Ultrathin Wearing Course
Publisher: ASCE
Abstract: An ultrathin wearing course (UTWC) is a preventive maintenance treatment method for a road surface which can improve the safety and comfort of driving by providing superior skid resistance. However, the skid resistance is ...
Unified Characterization of Rubber Asphalt Mixture Strength under Different Stress Loading Paths
Publisher: ASCE
Abstract: The research on the strength characteristics of rubberized asphalt pavement materials could provide calculation parameters for structural resistance design. However, the strength results of different methods varied ...
Surface Modification of Multiwalled Carbon Nanotube on the Performance of SBS Asphalt
Publisher: ASCE
Abstract: Multiwalled carbon nanotubes (MWCNTs) improve ultraviolet (UV) aging resistance and storage stability of asphalt modified with styrene-butadiene-styrene (SBS). However, MWCNTs have the disadvantages of poor dispersivity, ...
Packing Theory and Volumetrics-Based Aggregate Gradation Design Method
Publisher: ASCE
Abstract: Current gradation design in Superpave mix design method is an empirical-based trial-and-error method, which is costly and time-consuming. Moreover, few mechanical properties have been evaluated during the mix design to ...
Rheological Properties of Hot-Mix Asphalt during the Compaction Process Based on the Bodner–Partom Model
Publisher: American Society of Civil Engineers
Abstract: The traditional viscoelastic-plastic constitutive model of asphalt mixture is mostly suitable for the case of small deformation at room temperature, which may have difficulties in the evaluation of the large plastic ...
