Unravelling porous Asphalt Concrete with induction heating
Construction and Building Materials, 2014Co-Authors: Qian Liu, W. Yu, Erik Schlangen, Gerbert Van BochoveAbstract:? 2014 Elsevier Ltd. All rights reserved.Ravelling is the main defect of porous Asphalt pavement. An unravelling porous Asphalt was developed in this research. Steel wool was added to porous Asphalt Concrete and induction heating was used to heal the cracks at early stage to prevent ravelling. In this paper, the mixing procedure was optimized to disperse steel wool into Asphalt mixture, the induction heating potential of porous Asphalt Concrete containing steel wool was measured, and Rotating Surface Abrasion Test with rest periods to apply induction heating was employed to study the ravelling resistance improvement of porous Asphalt Concrete. It was found that porous Asphalt Concrete containing steel wool can be heated with induction energy and induction heating can greatly reduce the stone loss of porous Asphalt Concrete, despite when induction heating was applied. Porous Asphalt suffered less ravelling damage when induction heating was applied at an earlier stage. It is concluded that unravelling porous Asphalt can be achieved by applying induction heating and induction should be applied at an early stage.

Construction and Building Materials, 2011Co-Authors: Alvaro Garcia, Erik SchlangenAbstract:The objective of this paper is to detect the healing effect of Asphalt mastic and porous Asphalt Concrete caused by induction heating. It was found that the broken mastic beams could be healed many times by induction heating. Moreover, the stiffness of porous Asphalt Concrete recovered more and faster when induction heating was applied to the samples. It was also found that fatigue life of porous Asphalt Concrete was significantly extended by induction heating. Based on these findings, it was concluded that the self healing rate of Asphalt mastic and porous Asphalt Concrete can be increased by induction heating.

induction heating of electrically conductive porous Asphalt Concrete
Construction and Building Materials, 2010Co-Authors: Erik Schlangen, Alvaro GarciaAbstract:Abstract In this research, an electrically conductive porous Asphalt Concrete, used for induction heating, was prepared by adding electrically conductive filler (steel fibers and steel wool) to the mixture. The main purpose of this paper is to examine the electrical conductivity and the indirect tensile strength of this conductive porous Asphalt Concrete and prove that it can be heated via induction heating. It was found that, to make porous Asphalt Concrete electrically conductive, long steel wool with small diameter is better than short steel fibers with bigger diameter. However, steel fibers with short length and big diameter have better strength reinforcement capability than steel wool with long length and small diameter. It was also proved that conductive porous Asphalt Concrete containing steel wool can be easily heated via induction heating. Finally, 10% (by volume of bitumen) of steel wool type 000 was proposed as an optimal content in porous Asphalt Concrete to obtain an optimal conductivity, a good induction heating rate and an acceptable indirect tensile strength. It is expected that the autogenous healing capacity of Asphalt Concrete will be enhanced with the increase of temperature during induction heating.

induction healing of dense Asphalt Concrete
Construction and Building Materials, 2013Co-Authors: Alvaro Garcia, Moises Bueno, J Norambuenacontreras, Manfred N PartlAbstract:Induction heating can be used for repairing cracks in Asphalt Concrete. With this purpose, electrically conductive particles have to be added to the Asphalt mixture, which is then heated with an induction heating device. Since the factors affecting the induction healing of dense Asphalt Concrete are not well-known, in this article, different mixtures, with different lengths, quantities and diameters of steel wool fibres have been considered. It was found that there is a minimum temperature for healing Asphalt Concrete. Additionally a semi-empirical model, explaining Asphalt healing through the capillary theory has been developed and fitted to the results.

Preventive maintenance of porous Asphalt Concrete using surface treatment technology
Materials and Design, 2016Co-Authors: Yuan Zhang, Martin Van De Ven, Andre Molenaar, Shaopeng WuAbstract:Porous Asphalt Concrete is widely used as a surfacing layer on highways in the Netherlands because of its benefit that it is effective in reducing traffic noise. However, the service life of porous Asphalt wearing courses is limited due to the fact that it is vulnerable to raveling. A preventive maintenance strategy using surface treatment material is being considered as a cost-effective and environmentally sustainable option to extend the service life of existing porous Asphalt wearing courses. In this paper, the effect of a surface treatment to porous Asphalt wearing courses is discussed. A surface treatment material was sprayed on the porous Asphalt pavement surfaces in two field trials. Computed Tomography (CT) scans were performed on the porous Asphalt Concrete cores from the field trials to measure their volumetric properties. The rotating surface abrasion tests were used to determine the raveling resistance of the porous Asphalt Concrete samples. Finite element models with a realistic structure of the porous Asphalt Concrete were created for analyzing the stresses and strains as a result of traffic loads in the pavement surface with the surface treatment material. It is found that the effect of the surface treatment is positive.

study on volume performance of conductive Asphalt Concrete based on freeze thaw cycle
Applied Mechanics and Materials, 2013Co-Authors: Ning Tang, Ming Yu Chen, Shaopeng WuAbstract:Conductive Asphalt Concrete, a kind of intelligent materials, can serve as Asphalt solar collector, Asphalt heater and self monitor. And moisture damage is one of the most common performance degradation of Asphalt Concrete. This paper investigates the volume properties of conductive Asphalt Concrete based on Freeze-thaw cycles. Marshall specimen was frozen and thawed repeatedly and a cycle consists 16h at -18oC and 8h at 60oC. The change of air void and weight loss ratio were chosen to evaluate the moisture resistance of conductive Asphalt Concrete. Three types of Asphalt mixture (control, CAC 1 and CAC 2) were used to study the effect of initial void and material composition on moisture resistance. The results show that both the framework structures and the material composition have a great effect on antifreeze-thaw property of Asphalt Concrete, which provides an efficient guidance for application of this technology in pavement.

Classification of Fine Recycled Aggregate Used in Asphalt Concrete
Advanced Materials Research, 2011Co-Authors: Shaopeng Wu, Jin Jun ZhongAbstract:Two classification methods for fine recycled aggregate used in Asphalt Concrete were investigated in this paper, respectively classifying by fine recycled aggregate properties and Asphalt Concrete properties. When classifying by fine recycled aggregate properties, all test results of fine recycled aggregate properties can meet the technical requirements of China with obvious differences in quality. When classifying by Asphalt Concrete properties, fine recycled and natural aggregate was respectively used to prepare Asphalt Concrete with the same gradation, the same Asphalt, the same limestone mineral filler and the same coarse natural aggregate. Some related properties of Asphalt Concrete were discussed to classify fine recycled aggregate. It is proposed in this paper that fine recycled aggregate should be classified into three types by Asphalt Concrete properties and the proposed classification criterion is given.

Applied Mechanics and Materials, 2011Co-Authors: Shaopeng Wu, Jin Jun Zhong, Dong Ming WangAbstract:Two classification methods for coarse recycled aggregate used in Asphalt Concrete were investigated in this paper, respectively classifying by coarse recycled aggregate properties and Asphalt Concrete properties. When classifying by coarse recycled aggregate properties, coarse recycled aggregate was classified into three types by the apparent specific gravity, water absorption, crushed value, Los Angeles abrasion value and brick content of coarse recycled aggregate. When classifying by Asphalt Concrete properties, coarse recycled aggregate was used to prepare Asphalt Concrete; and coarse recycled aggregate was classified into three types by the optimum Asphalt content ratio (ROAC), theoretical maximum specific gravity ratio (RTMSG) and indirect tensile strength ratio (RITS) of Asphalt Concrete containing coarse recycled aggregate. The proposed classification criterions of the two classification methods were respectively given.

Fractal features of cracking of self-monitoring Asphalt Concrete
2011 International Conference on Mechatronic Science Electric Engineering and Computer (MEC), 2011Co-Authors: Shaopeng Wu, Ning Tang, Lei Chen, Shaoxu HuangAbstract:Self-monitoring Asphalt Concrete has a good electrical behavior. The monitoring of damage is valuable for structural health monitoring and service life prediction. In this paper, the process of cracking of self-monitoring Asphalt Concrete cracks were quantitatively described by indirect tensile test and combination of mathematical fractal theory. The test results show that the distribution of self monitoring Asphalt Concrete crack has obviously statistical similarity, and cracks with a clear statistical significance of cracks on the fractal. There is a good congruent relationship among fractal dimension, resistance and deformation, which provides a new thought to the research of the cracking of self-monitoring Asphalt Concrete.
