Use of digital technology to improve the way asphalt roads are constructed

Digital technology has the potential to improve the way asphalt roads are constructed and maintained. The application of technologies, such as remote monitoring and telemetry, are being used to improve the quality of asphalt materials during the construction phase. Based on real-time data, the movement and arrival of delivery vehicles can be monitored and material temperatures can be recorded at each stage of the paving process. Similarly, roller compactor passes can be mapped to show the number of passes, compaction temperature and area of mat covered. Importantly, the technology has the capacity to create a safer working environment for road workers. This paper describes a study that builds on previous work, with the aim of developing notes for guidance and compliance requirements for electronic data monitoring. A series of criteria are proposed to approve the level of compaction based on electronic data. The latter includes the adoption of a similar approach to that being used in the USA, although certain aspects have been adapted for the type of materials and equipment available in Scotland. It is intended that the compliance requirements will be trialled on forthcoming paving schemes to determine their effectiveness and whether further amendments are required.
