CRISPS Webinar – Developing a Quality Control Framework for Epoxy Bitumen: From Theory to Practice
March 1, 2022 @ 8:00 am – 9:00 am CET
About the Webinar
A quality control system is essential during any road construction or maintenance activities to ensure an extended asset life and lower life cycle cost. Despite the importance of ensuring the quality of road surfacings, the literature suggests that there is a lack of quality control procedures for road surfacing material construction, especially in Low and Middle-income countries, which is leading to poor-quality road surfaces. Further to this, there is limited literature on the control of epoxy asphalt bitumen content.
This webinar held on 1st March 2022 presented early findings from the “Climate-resilient sustainable road pavement surfacing (CRISPS)” research programme funded by the UK Aid’s High Volume Transport Applied Research Programme (HVT) in collaboration with the University of Birmingham (UoB), the University of Auckland (UoA), the Universiti Putra Malaysia (UPM) and the International Road Federation (IRF). This webinar seeked to support the development of a quality control methodology and framework for the material and methods associated with constructing roads using epoxy bitumen.
The webinar provided a review of existing quality control methods and their application in low and middle-income settings. It also described the general components of a quality control system in the construction of road pavements, comprising the following elements: Control of materials and methods; Control of end-product.
This webinar concluded with an introduction to experimental approaches to the characterisation of chemical and physical performance of epoxy-modified bitumen.
By developing a framework for quality control, higher durability and hence lower life cycle cost can be achieved for the epoxy bitumen road surfacings. This is essential to support the development of climate-resilient and sustainable roads that are able to manage changes in climate, e.g. hotter seasons, more extreme precipitation events, and sea-level rise that impinge on road pavement performance in Low and Middle-Income countries. Failure to account for such impacts in future road design, maintenance, and operations planning could cause accelerated road deterioration and higher road use costs, thereby severely constraining socio-economic development.
