ABSTRACT
This paper examines the extent to which using spray preservation technology seals trench reinstatements to reduce hydraulic conductivity and extend the life of the repaired area firstly on both the reinstatement installation constructed from conventional Hot Mix Asphalt (HMA) and secondly on a new novel reinstatement installation material made from LJMU new fast curing Cold Mix Asphalt (CMA) with no CO2 emission. The significant improvements in the HMA and CMA trial sections hydraulic conductivities, skid resistance, together with the high improvements in the CMA indirect tensile stiffness, and void contents are evidence on the benefits of the spray in pre-longing the life of the repaired areas in this innovation. All sections of the trial shows high performance under real traffic and environmental conditions over the 12 months of site monitoring. This will ensure benefits of reducing the cost of current re-work, and an overall decrease in the carbon footprint.
