Asphalt Concrete Pavement

Abstract Flexible or asphalt concrete pavement is the paving system most widely adopted all over the world. It has been recognized that there are many different types of the factors affecting the performance and durability of asphalt concrete pavement, including the service conditions, such as: the variation of temperature from mild to extremes and the repeated excessive axle loading as well as the inadequate quality of the raw materials. All of these when combined together are going to accelerate the occurrence of distresses in flexible pavement such as permanent deformation and fatigue cracking. As the result, there has an urgent need to enhance the ability of asphalt concrete mixture to resist distresses happened in pavement. Use of additives is one of the techniques adopted to improve pavement properties. It has been found that hydrated lime might be one of the effective additives because it is widely available and relatively cheap compared to other modifiers like polymers. This paper presents an experimental study of the hydrated-lime modified asphalt concrete mixtures. Five different percentages of the hydrated lime additive were investigated, namely (1, 1.5, 2, 2.5 and 3 percent). The hydrated lime additive was used as partial replacement of limestone filler by total weight of the aggregate. The designed Hot Mix Asphalt (HMA) concretes are for the application of three pavement courses, i.e. Surface, Leveling and Base. These mixtures are designed and tested following Marshall procedure and uniaxial repeated loading to evaluate permanent deformation at different temperatures of 20°C, 40°C and 60°C. The experimental results show that the addition of hydrated lime as a partial replacement of ordinary limestone mineral filler results a significant improvement on mechanical properties and the resistant to permanent deformation of the designed asphalt concrete mixtures.

Abstract : Endurance of asphalt concrete pavement on traffic load and temperature depends on the type and composition of aggregates, asphalt and filler used. Many attempts have been made to improve the quality of the mixture, such as using modified asphalt. Modified asphalt made by mixing asphalt pen. 60/70 with addition material. In this research, we used crumb rubber as an aggregate substitute material on AC-BC mixture. This study aims to determine the influence of additional substitution of used crumb rubber. The first step of the research is to find the optimum asphalt content (OAC), then add the crumb rubber as an aggregate substitute material from 0%, 1%, 2%, 3%, 4% and 5% to the weight of the mixture. The results showed that the percentage of crumb rubber influenced Marshall parameters value, especially the value of stability, VIM and VMA at 5.285% asphalt content. The highest stability value was found in the mixture of 2% crumb rubber is 1128.48 Kg. The highest VIM value is in the 5% mixture of the used crumb rubber is 16.94%. The highest VMA value is in the 5% mixture of the used crumb rubber is 27.88% and the highest flow value is in the 5% crumb rubber mixture of 4.97 mm. However, in MQ value increase and decrease that happened very big. No big changes in the density and VFA values for all substitutions of crumb rubber. For the durability value of AC-BC mixture with crumb rubber variation 90% requirement only on crumb rubber 1%.Abstrak: Ketahanan perkerasan beton aspal terhadap beban lalulintas dan temperatur sangat tergantung pada jenis dan komposisi agregat, aspal serta filler yang digunakan. Banyak usaha telah dilakukan untuk meningkatkan kualitas campuran, salah satunya dengan menggunakan aspal modifikasi. Aspal modifikasi dibuat dengan mencampur aspal pen. 60/70 dengan bahan tambah.

Infrared Thermal Imager

Although there is a large population in the limited space of metropolitan areas in Taiwan, but many manholes are often set on the pavement, which impact the quality of the pavement service and lead to public complaints. In recent years, the manholes have been gradually buried under the pavement on policy, so as to improve administration performance of government. The construction quality at the location of manhole is not easy to control, and often leads to the pavement damaged. This study assesses the differences of the temperature changes at manhole location from the general asphalt concrete when paved with asphalt concrete using the infrared thermal imager. The study found that the use of infrared thermal imager can get the difference of temperature of asphalt concrete pavement between the manhole position and the non-manhole position, and also can determine the position and width of manhole, so as to help to the construction compaction and quality control. Furthermore, because the temperatures of pavement at manhole position and non-manhole position are different, when the pavement damaged and need to dig the pavement for maintaining, the infrared thermal imager can be used to find nonmetallic manhole for construction management reference.

With the rapid development of new technologies, such as big data, the Internet of Things (IoT) and intelligent sensing, the traditional asphalt pavement construction quality evaluation method has been unable to meet the needs of road digital construction. At the same time, the development of such technologies enables a new management system for asphalt pavement construction. In this study, firstly, the dynamic quality monitoring system of asphalt concrete pavement is established by adopting the BeiDou Navigation Satellite System, intelligent sensing, the IoT and 5G technology. This allows key technical indicators to be collected and transmitted for the whole process of asphalt mixture, which includes the mixing plant, transport vehicle, paving and compaction. Secondly, combined with AHP and the entropy weight (EW) method, the index combination weight is calculated. The comprehensive index for the pavement digital construction quality index (PCQ) is proposed to reflect the impact of monitoring indicators on pavement quality. An expert decision-making model is formed by using the improved particle swarm optimization (PSO) algorithm coupled with radial basis function neural network (RBF). Finally, the digital monitoring index and pavement performance index are connected to establish a full-time and multi-dimensional digital construction quality evaluation model. This study is verified by a database created from the digital monitoring data of pavement construction collected from a highway construction project. The system proposed in this study can accurately reflect the quality of pavement digital construction and solve the lag problem existing in the feedback of construction site.

Prefabricated construction quality can not only influence the service life and function of buildings, but is also closely associated with the users’ safety. Therefore, effective quality management is significant for the development of this type of construction method in this industry. The current research regarding quality management in the field of construction mainly focuses on on-site construction, while lacking extensive attention to prefabricated construction. Based on the existing literature and expert opinions from the construction firms, the government, and academia, this paper summarizes 23 critical factors that affect the quality management of prefabricated construction, adopts the interpretation structure model-matrix cross-reference multiplication applied to a classification (ISM-MICMAC) to analyze the hierarchical relationship between these factors, and further investigates the influence degree of the relationship by using the decision-making trial and evaluation laboratory (DEMATEL). The result shows that the government guidance is the most important influencing factor, and other factors, including integration in the supply chain, laws and regulations, codes and standards for prefabricated components, technology, and professional personnel, etc., also play a critical role in the quality management of prefabricated construction. These factors can affect the quality of raw materials for the production, manufacturing and transport equipment of prefabricated components through assembly and design schemes, ultimately resulting in an influence on the quality of prefabricated construction. The study aims to identify a mutual relationship between the critical factors affecting prefabricated construction quality, which can help managers to have a better understanding of the quality of prefabricated construction, and take effective measures to improve the status quo as well as promote the sustainable development of prefabricated construction.
