When the temperature of asphalt concrete is above a certain threshold, bitumen may start flowing through any possible crack and healing it. Induction heating technique for increasing mixture. It consists adding electrically conductive magnetically susceptible particles to These can be heated thanks action an induction apparatus. The objective this article investigate effect different mixture porosities types on induction-healing rates concrete. With purpose, semi-circular test samples made...
Abstract This paper summarizes the main results of experimental research on induction healing dense asphalt concrete with steel wool fibers. Different physical properties concrete, as fibers distribution, mechanical properties, thermal conductivity, and via heating have been analysed. The show that short thick disperse very well in mixture, while long thin produce clusters. It was also observed can be damaged during mixing compaction processes. In addition, it found do not significantly...
This paper presents the self-healing results of asphalt mixtures by action capsules containing sunflower oil as encapsulated rejuvenator. Three different capsule contents, 0.10, 0.25 and 0.50% total weight mixture, were added to samples. The mechanical thermal properties have been evaluated. In addition, effect addition healing temperature on evaluated through three-point bending tests cracked beams with, without, capsules. test was implemented comparing strength recovery broken after their...
This paper re-evaluates the effect of sunflower oil capsules on mechanical and self-healing properties dense-graded asphalt mixtures. Different percentages (0.50 wt%, 0.75 wt% 1.00 wt%) were mixed into dense asphalt. The influence such as density, indirect tensile strength, particle loss, fatigue life, self-healing, has been investigated. distribution integrity also evaluated by means CT Scans. It proven that can survive mixing compaction process mixture, do not decrease its they rupture...
This paper aims to evaluate the influence of microwave heating time on self-healing properties fibre-reinforced asphalt mixtures. To this purpose, dense mixtures with four different percentages steel wool fibres were evaluated as three-point bending strength before and after healing via at times. Furthermore, thermal behaviour during was also evaluated. With aim quantifying efficiency repair process, ten damage-healing cycles done in test samples. In addition, results compared fibre spatial...
This paper presents an experimental study to evaluate the mechanical and crack-healing properties of stone mastic asphalt (SMA) mixtures with encapsulated rejuvenators. With this goal, calcium alginate capsules sunflower oil as rejuvenating agent have been manufactured added into SMA mixtures. Physical without evaluated following British standard tests. Healing by action assessed using three-point bending (3PB) tests applied on test beams conditioned at different healing times, from 5 216 h....
Segregation of waste crumb rubber powder (WR) modified asphalt binders the large-scale application WR in asphalt. The method microwave activation combined with chemical (KMWR) was proposed to improve storage stability and rheological properties this work. Storage virgin asphalt, MWR KMWR were comparatively studied by standard segregation test, bending beam rheometer (BBR) dynamic shear (DSR) test. effect composite on particles Fourier-transform infrared spectroscopy (FT-IR), scanning...
Asphalt pavements and bituminous composites are majorly damaged by bitumen aging fatigue cracking traffic load. To add, maintenance reparation of asphalt is expensive also releases significant amounts greenhouse gases. These issues can be mitigated promoting self-healing mechanisms with encapsulated rejuvenators. The ability the required microcapsules to resilient against high temperatures, oxidation, mechanical stress essential promote such behavior without compromising field performance...
