A Performance-Based Design Framework for Enhanced Asphalt Concrete in the Caribbean Region

The majority of recent research in has been focused on the introduction, development, and evaluation performance-based specifications for design asphalt concrete mixtures. In Caribbean, most laboratories only use Volumetric Marshall Mix methodology. Road designers, engineers, consultants, contractors have all highlighted many shortcomings inadequacies volumetric mix selection process. consensus is that there a need to develop process addresses service’s performance common distress pavements through design. Performance-Based Design (PBMD) used as practical alternative technique evaluating pavement distresses by incorporating testing conjunction with parameters into This study describes findings our comprehensive laboratory research, which was conduced facilitate development framework methodology involved collection integration qualitative quantitative data case studies experimental work. Two control two PBMD mixtures were designed evaluate both properties address permanent deformation (rutting), fatigue cracking, stiffness, moisture susceptibility. led test criteria deformation, stiffness modulus, an acceptable tensile strength ratio. implementation PMBD Caribbean region could exemplify significant step towards achieving sustainable region. framework, incorporates best-practice solutions, anticipated increase awareness about variables affect
