A Review on Phase Change Materials Incorporation in Asphalt Pavement

This research is an attempt to use PCM technology in order to protect and treat the asphalt pavement from the influence of temperatures and thus not to crack the road pavements. Applying the phase change materials in roadway traffic domain is becoming an exploration research, although the PCM have been used in many fields. Depending on the properties of latent heat, we can apply the phase change materials to control and regulate temperature of asphalt pavement and keeping mix feasibility. Asphalt pavement is a material that can heat up to 60°C due to solar irradiation in summertime because of their excellent heat-absorbing properties. Using the PCM can treat the asphalt mixture pavement cracks related to temperature, enhance the performance of asphalt concrete pavement, and prolong the service life of asphalt concrete pavement. We address the procedure bitumen penetration grade 50/60 was used in this test. In this study, gravel and sand are used as coarse and fine aggregate respectively in hot mixture asphalt. In order to apply PCM in asphalt concrete pavement, mechanism of controlling temperature, road performance and mixture design method of asphalt mixture have been considered. Results show that maximum temperature of surface and bottom respectively is (43.41°C, 46.47°C), and the maximum absolute Delta (difference between surface and bottom) reached to 4.72°C.

The objective of this paper is to evaluate the fatigue resistance and self-healing properties of asphalt binders modified with different types of additives (Styrene-Butadiene-Styrene (SBS), Glass Powder (GP) and Phase-Change Materials blended with Glass Powder (GPCM)). Two base binders were used in this study: a PG 58-28 straight-run asphalt binder and a PG 70-28 Polymer modified with 3%SBS. Moreover, the GP was added to the two base binders at two different percentages of 3.5% and 5% by binder weight. However, the GPCM was added with two different percentages of 5% and 7% by binder weight. In this paper, the fatigue resistance and self-healing properties were evaluated using Linear Amplitude Sweep (LAS) test. Two different procedures were adopted. In the first procedure, the load was applied continuously until failure (without a rest period), whereas, in the second procedure, rest periods of 5 and 30 min were introduced. The obtained results of the experimental campaign were ranked based on three different categories: Linear Amplitude Sweep (LAS), Pure Linear Amplitude Sweep (PLAS) and modified Pure Linear Amplitude Sweep (PLASH). The addition of GPCM appears to positively impact the fatigue performance of both straight-run and polymer-modified asphalt binders. Furthermore, when a short rest period of 5 min was introduced, the use of GPCM did not appear to improve the healing potential. However, a better healing capacity was observed when the 30 min rest period was applied. Moreover, the addition of GP alone to the base binder was not beneficial in improving fatigue performance based on LAS and PLAS methods. However, there was a slight reduction in the fatigue performance based on the PLAS method. Finally, unlike the PG 58-28, the healing capacity of the GP 70-28 was negatively affected by the addition of the GP.
