| description | This study aims to investigate the crack-healing of asphalt mixture by induction heating of bitumen-thermoplastic
binder. This system employs a heterogeneous mixture, in which different percentages (2, 4, 6, and 8% by weigh) of
thermoplastic healing agent (polyethylene (PE) and polypropylene (PP)) dissolve with the bitumen, respectively. Healing
was achieved by heating the fractured asphalt composite to a specific temperature; in which heterogeneous blend
has undergone random molecule diffusion and volumetric thermal expansion of healing agent within the matrix. The
thermal properties in the bitumen-thermoplastic were characterized by means of dynamic mechanical thermal analysis
(DMTA); in which the glass transition temperature (Tg
) has been used as a reference for the healing process. The FTIR
shows no chemical reaction between bitumen and thermoplastic. Three-point bending test was conducted to demonstrate
details crack-healing capability in asphalt composite. The results show that 6% of PE and PP to the mixture of bitumenthermoplastic has the highest tensile strength. The percentage of recovery was also measured through the healing
cycle process using a three-point bending test. Overall, within the third healing cycle, asphalt composite with
modified bitumen (with PP or PE) shows 98-55% of healing recovery. The best percentage recovery is using bitumen-PP
mixture with a ratio of 94:6. The crack-healing process was also proven through the surface and cross-section asphalt
morphology analyses using optical microscopy and scanning electron microscope (SEM). |
