Energy supply technologies (induction and microwave heating) have demonstrated significant efficacy in enhancing the crack healing capability of asphalt pavement,
7 dec. 2021 — Self-healing is an effective method of enhancing the ability of asphalt pavement to heal, especially on micro cracks healing as addressed by Ghazali et al.,
10 feb. 2018 — Cracks in asphalt pavements can be healed effectively using healing agents. •. Crack healing depends on agent type, healing time and aging of mixture. •. Initial
12 ian. 2024 — The self-healing properties of asphalt pavements reduce the need for frequent maintenance and repair of cracks and promote road sustainability. In this study,
1 oct. 2022 — Asphalt concrete (AC) pavements are subjected to repeated loading due to moving traffic. Rutting and cracking are the two common distress types in AC pavements due to traffic loading (Motamedi et al., 2021).Fig. 1 shows the critical points in the pavement layers under a wheel. T and C indicate the tensile and compressive modes, respectively.
The RILEM Technical Committee 278-CHA (Crack-Healing of Asphalt Pavement Materials) was founded in 2016 and the TC deals with healing phenomena of asphalt, a subject which becoming more and more popular in the last decade. The focus is on the development of test methods for the induction of asphalt cracking, quantification of
25 sept. 2021 — The symposium represents a joint effort of three RILEM Technical Committees from Cluster 264-RAP “Asphalt Pavement Recycling”, 272-PIM “Phase and Interphase Behaviour of Bituminous Materials”, and 278-CHA “Crack-Healing of Asphalt Pavement
26 sept. 2021 — The Rilem Technical Committee TC 278-CHA (Crack-Healing of Asphalt Pavement Materials) was created in 2016 to tackle the challenges related to testing and evaluating the crack-healing properties of bituminous materials. However, the committee members noticed that there is no clear agreement within the scientific community about
Cracking is one of the most prevalent deterioration modes of flexible pavements. It is caused by traffic loading, low temperature and can be accelerated by oxidation of the asphalt or when the asphalt material performs poorly. In research on asphalt pavement, these issues have often been addressed separay due to the varied reasons for the
1.1 Self-healing properties of asphalt pavement Asphalt pavement is a self-healing material. When subjected to rest periods, asphalt pavement the potential to restore its stiffness and strength by closing the microcracks which occur when the pavement is subjected to traffic loads. Research to date
1 feb. 2016 — The phenomenon of healing in asphalt pavements2.1. Healing in asphalt pavements as a general concept. Materials that possess healing ability when exposed to damage through thermal, mechanical, ballistic or other means are able to heal and recover themselves and restore their original set of properties (Liu, 2012, Wool,
8 sept. 2021 — The second part of the research experiment showed the large potential of the microwave crack healing technique. The asphalt pavement was healed on its full depth of 10 cm with the single healing operation applied. Although some limitations may occur in the practical use of microwave heating, the test results suggest that it is a very promising
10 nov. 2023 — Asphalt pavement consists of a mixture of bitumen and aggregates. Compared to concrete pavement, asphalt pavement has the superiorities of a short construction period, comfortable driving, and low noise. However, micro-cracks in asphalt pavements can occur under the combined long-term effects of load and environment [1],
21 mar. 2024 — vehicle load before microcracks occurred in asphalt pavement. 1. Introduction In order to alleviate the cracks caused by vehicle and temperature variation, self-healing asphalt pavement have been proposed. The self-healing ability of asphalt pavement itself is small, so the serious cracks caused by heavy vehicle loads, low
