Performance Study on Modified Asphalt Cement Using Trinidad Lake Asphalt (TLA) as a Polymer Modifier

open access: yesJournal of Smart Science and Technology
Asphalt binders play a crucial role in pavement performance by providing the necessary viscoelastic properties to withstand traffic loads and environmental stressors. This study investigates the rheological characteristics of Trinidad Lake Asphalt (TLA) blended with penetration grade (PEN 60/70 and PEN 160/220) binders to assess suitability for road ...
