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


  1. Refining the PQi method, tools, data collection, data analytics and innovative visuals (e.g. GUI)

  2. The implementation & integration of real-time process control systems and practical tools for planning, construction, and logistics (descriptive to prescriptive, system integration approach)

  3. 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


  1. Data acquisition, sharing and exchange using SMART technologies

  2. Data-driven simulation and modelling for various life cycle phases

  3. 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.


  1. Developing and maintaining education materials for all levels of education

  2. Enhancing capacity building for the entire sector using workshops, seminars and symposia

  3. 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.


  1. Designing strategies, systems and monitoring tools for emission-free equipment & jobsites

  2. Designing preventative maintenance strategies

  3. Developing pavement performance and degradation models using design, construction, inspection and other data

  4. Exploring and developing climate change strategies for the pavement lifecycle (models, guidelines, frameworks, decision-support tools)

  5. Developing guidelines for systemic decision-making
