Self-Healing Technology of Asphalt Pavements
Journal Title: International Journal of Innovative Research in Computer Science and Technology - Year 2022, Vol 10, Issue 3
Abstract
Cap heal reduces the environmental pollution and improves the performance of asphalt pavement. Since large amount of budget is allocated to road construction, so there is a need to implement more economically and environmentally sustainable practices. However rheological properties of the pavement after using rejuvenator were determined by penetration, softening point, viscosity and ductility. Cap heal as a rejuvenating agent is used to restore aged asphalt of different aging degree and the effect of cap heal on the reclaimed properties is investigated. The results indicate that cap heal can make the properties of aged asphalt restore its strength properties and make it durable, anticreeping and self healing. The main aim of using this cap heal is to make it economical and feasible by saving the maintenance cost. The mixing amount of cap heal increases with the aging degree. For the asphalt sample which aged for 5h, 2% of mixing amount can make the penetration, softening point, ductility of aged asphalt restores. For the asphalt sample which aged for 7.5h and 10h, 4% of mixing amount can make the penetration, softening point, ductility of aged asphalt restores. Compared with original asphalt, the construction temperature of regenerating asphalt increases slightly. Adhesion ability between aggregate and asphalt is affected by cap heal and anti-stripping materials are expected to be used.
