Resumen

In the present research, asphalt briquettes were manufactured using tailings-derived filler as an aggregate. The hot mix asphalt (HMA) design corresponds to the MAC-1 type, which is intended for heavy traffic, as the study area is based on roads near mining districts where heavy transport vehicles operate at an altitude exceeding 3,000 meters above sea level. The design follows the Technical Specifications MTC EG-2013 Section 423, which specifies that the mix must be composed of stone materials such as gravel and sand that meet certain requirements. The asphalt binder used is conventional PEN 85-100 asphalt from the company Petróleos del Perú – PETROPERÚ S.A.C., which complies with the requirements of Technical Specifications Section 426. Additionally, tailings-derived filler was incorporated into the mix. The briquettes were manufactured following the methodology of the Marshall Method for hot mix asphalt.
