Research themes
Based on the aforementioned, 4 main themes (pillars) are distinguished for the ASPARi program for 2023-2026, in which the various initiatives, developments and projects can be clearly defined and incorporated. The outcomes are encapsulated in the following infographic (Figure 2):

Figure 2 - Proposed main themes
Theme 1: Improving process control
Purpose: Reduction of process variability
Through:
-
Refining the PQi method, tools, data collection, data analytics and innovative visuals (e.g. GUI)
-
The implementation & integration of real-time process control systems and practical tools for planning, construction, and logistics (descriptive to prescriptive, system integration approach)
-
Developing innovative, non-invasive ways of measuring parameters such as layer thickness and density in real-time
​
Theme 2: Digitalization
Purpose: Attain improvements in quality and productivity for the entire life cycle
Through:
-
Data acquisition, sharing and exchange using SMART technologies
-
Data-driven simulation and modelling for various life cycle phases
-
Developing Pavement Lifecycle Digital Twins to seamlessly integrate processes, people, technologies, and products
​
Theme 3: Education and training
Purpose: to ensure that current and future skills and competencies are relevant given the context of Industry 4.0.
Through:
-
Developing and maintaining education materials for all levels of education
-
Enhancing capacity building for the entire sector using workshops, seminars and symposia
-
Developing innovative tools (e.g. simulators, VR and AR) for the training of new and current construction staff
Theme 4: Monitoring and Durability
Purpose: To reduce the sector’s impact on the environment and address drivers of change such as the energy transition, the need for increased durability and a more sustainable asphalt sector.
Through:
-
Designing strategies, systems and monitoring tools for emission-free equipment & jobsites
-
Designing preventative maintenance strategies
-
Developing pavement performance and degradation models using design, construction, inspection and other data
-
Exploring and developing climate change strategies for the pavement lifecycle (models, guidelines, frameworks, decision-support tools)
-
Developing guidelines for systemic decision-making
