Project 1.9 (2022)

Multifunctional pavements materials and application analysis

The project aims to investigate the multi-functionality of pavement materials and to improve the properties of these materials and their application potential. As pavement is one of the most important elements of modern transportation systems, we need to improve its durability and serviceability. Environmental factors like temperature and humidity, as well as vehicular loading, can cause damage to pavements. Several novel technologies will be developed in this project, making use of self-sensing, self-healing, and temperature-control technologies to enhance the lifespan of pavement materials. Another potential goal of the project is to achieve environmentally-friendly pavements. One of the multi-functions of pavement materials can potentially be absorbing and degrading carbon emissions from vehicles, leading to a more efficient method for environmental protection.

Project Objectives
(1) To study the piezoresistivity of self-sensing cementitious composites as cement-based sensors
(2) To investigate the durability of self-sensing cementitious composites as cement-based sensors
(3) To improve the reliability of self-sensing cementitious composites as cement-based sensors to the change in the environment
(4) To explore the application of photocatalytic technology, self-healing technology, and thermochromic materials for asphalt concrete pavement
(5) To develop multifunctional concrete for smart pavements of transport
