Objectives: The study presents the experimental results of testing an MD-1 porous asphalt mixture modified by wet and dry process with a natural asphalt type Gilsonite (G) from Cesar (Colombia). Methods/Analysis: For the preparation of the mixtures, an Asphalt Cement (AC) type AC 60-70 (PG 64-22) was used. For the evaluation of the resistance to abrasion and monotonic load of the control mixtures (without Gilsonite) and modified, the Cantabro and Marshall tests were used, respectively. Findings: We report a remarkable increase in the stiffness under monotonic load and in the resistance to abrasion when a ratio of Gilsonite and AC of G/AC=10% is used. Application/Improvement: Gilsonite can be used to improve resistant to abrasion and cohesion properties (increasing stiff and monotonic mechanical resistance) of porous asphalt mixtures which are used in pavements to improve wet-weather visibility and friction, tire spray, hydroplaning, storm water management and skid resistance.
