A Comparative Review of Hot and Warm Mix Asphalt
However, warm-mix asphalt (WMA) was introduced by pavement researchers and the road construction industry instead of hot-mix asphalt (HMA) to reduce these environmental problems. This study aims P = % Passing. d = Size of sieve opening. D = Largest size in gradation. Four dense graded mixtures of hot mix asphalt incorporating recycled asphalt pavement percentages of 0%, 30%, 60% and 90% were designed based on the specifications of the Saudi Ministry of Municipal and Rural Affairs for the construction of urban roads- Part-7.Sustainable applications of asphalt mixes with reclaimed asphalt

Pavement Performance and Ice-Melting Characteristics of Asphalt
Icy pavement is one of the primary causes affecting driving safety in winter, and deicing asphalt mixture could effectively resist pavement icing. This study evaluated the effect of a slow-release deicing agent on pavement performance and ice-melting characteristics of the asphalt mixture. The asphalt mixture containing four In the construction of asphalt pavement, poor quality is often the main reason for damage to the pavement, which necessitates the use of monitoring systems during the construction stage. Therefore, this study focuses on building an asphalt concrete pavement construction monitoring system to monitor the construction phase. Through a System Framework for Digital Monitoring of the Construction of Asphalt

Investigation on the Temperature Distribution of Asphalt
Temperature is known to be one of the most important factors affecting the design and performance of asphalt concrete pavement. The distresses of asphalt overlay are closely related to its temperature, particularly in Guangxi, a hot-humid-climate region in China. This research is to analyze the impact of meteorological factors on temperature at This study presented a finite element model of radial tire–asphalt pavement interaction using ABAQUS 6.14 software to investigate the skid resistance properties of asphalt pavement under partial tire aquaplane conditions. Firstly, the pavement profile datum acquired by laser scanning were imported to Finite Element Anti-Skid Characteristics of Asphalt Pavement Based on Partial

A Sustainable Approach for the Maintenance of Asphalt Pavement
The aim of this paper is to present a new decision support concept (DSC) related to the ever-growing problem of the maintenance of damaged asphalt pavements. In the process of defining a sustainable approach to resolving this problem, we found complexity in the different needs considering economic, social, and technical aspects. An Microwave heating of asphalt mixtures containing metal fibers (steel wool) is a promising technology for asphalt pavement rehabilitation by self-healing. In fact, the optimal steel wool content assessed is around ten times less than the one recommended for heating by electromagnetic induction, which in practice could mean an important Self-Healing Asphalt: A Systematic Bibliometric Analysis for

Improving the Mechanical Properties of Recycled Asphalt Pavement
Due to its environmental and economic advantages, the use of recycled materials in asphalt mixes is witnessing increased interest, where the properties of those mixes are significantly affected by the properties of the recycled materials in them. This paper discusses the results of an experimental study conducted to evaluate the This study aims to evaluate the permanent deformation of high-modulus asphalt pavement in special road using viscoelastic theory. Based on the creep test, the Prony series representation of Burgers model parameters for different asphalt mixtures were obtained and used in the deformation simulation of a high-modulus asphalt Simulation of Permanent Deformation in High-Modulus Asphalt Pavement

A Review on Using Crumb Rubber in Reinforcement of Asphalt Pavement
An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as Because the indoor test environment was not necessarily consistent with the actual outdoor situation, the heat-reflective asphalt pavement coating was brushed on the asphalt pavement.

Applying Feasibility Investigation of Resin Modifying Agent in Asphalt
In order to promote the resin modifying agent applied into pavement materials, a type of resin modifying agent was selected as the modifier to prepare modified asphalt. The molecular crystal structure of the modifying material was characterized by using the X-ray diffraction test (XRD). The microstructure and element composition of In summer, black asphalt pavement can absorb a considerable amount of solar radiation, which causes its temperature to rise. Heated asphalt pavement can aggravate the urban heat island (UHI) effect and transfer heat downward, which may cause the problem of permafrost thawing beneath pavements.

Self-Healing Technology for Asphalt Pavements SpringerLink
Asphalt pavement is a self-healing material. When subjected to rest periods, asphalt pavement has the potential to restore its stiffness and strength by closing the micro-cracks that occur when the pavement is subjected to traffic loads. Research to date has focused on its autogenous healing properties (see Table 2 ).The use of reclaimed asphalt pavement (RAP) to create recycled asphalt mixture is attracting great interest because of landfill space decrease and natural resources saving. Also, incorporating rejuvenators is an effective method to promote the utilization of RAP materials in hot mix asphalt (HMA) production.
