Asphalt Pavement using Real Time Digitisation Technology
Project Objectives/ Outcomes:
Lagan Asphalt have just completed the pavement works on the N4 Dual Carriageway Castlebaldwin to Collooney Project. Despite the latest lockdown in Q1 Lagan managed to meet the Main Contractor program and complete for the STAYCATION summer holiday period!
Always striving to improve, Lagan have embraced the latest available technology and have installed Highway Data Systems (HDS) autonomous Quality Assurance System on the project. The HDS bespoke Etec system is linked to the Lagan weighbridge which extracts the dispatched docket information and transmits to the control unit at the laying operation. This gives full traceability of material placement location, delivery and rolling temperature information. Lagan Technical staff can periodically review real time information on site whenever they require it.
In addition, the Voelkel Navigator Roller System has been fitted to two brand new Hamm HD90+ rollers. This system records complete roller movements through GPS from the start of the shift right throughout the day. This innovative quality system gives the roller operator real time compaction data to ensure the full pavement area receives the required number of roller passes and compaction. Both systems are monitored from HDS Headquarters in Hertfordshire in the UK, with data been sent direct from the machines on site in Sligo, with regular updates coming back to the Lagan Asphalt Technical team on a regular basis. The significant benefits to our work practices for Quality, Environmental and Health & Safety are very substantial
