With growing concerns around stormwater and road safety, porous pavement technologies have emerged as a legitimate option for improved drainage performance, new solutions for stormwater reduction and enhanced road safety. However, the long-term economic deterrent of construction and maintenance retains a problem with porous pavement. The study evaluates the life cycle cost effectiveness of OGFC, SG and BC-2 with and without Induction Sensitive Fibres (ISF). It used a holistic process for LCCA, including laboratory performance data, service life assessment, maintenance cost forecasting, net benefits analysis and software calibration with Athena Pavement LCA. A total of 9 different mixture-binder combinations were assessed in terms of mechanical parameters (Marshall Stability, Indirect Tensile Strength, Tensile Strength Ratio) and functional and durability requirements (permeability, skid resistance, Cantabro Loss, fatigue performance). The use of ISF enhances the mechanical properties and durability characteristics of all three mixtures, leading to an increased service life and reduced maintenance requirements for a longer period. While the addition of fibres increased initial construction cost, the resultant savings on maintenance reduced overall life cycle costs of both OGFC and SG mixtures, in which PMBs (PMB-40 and CRMB-55) were generally found to be more economical than conventional VG-40. With respect to both service-life extension and savings in maintenance costs, the SG mixture modified with CRMB-55 binder yields the most optimal cost-benefit ratio overall; the combined effects of low-cost BC-2 mixtures - which provided high structural strength - led only to relatively minor service-life gains. The results of the manual assessment internal to Pavement LCA were also compared against those returned from the Athena Pavement LCA software, allowing for consistent trends in maintenance savings and increasing even further confidence in the overall manual framework established.
