graded asphalt concrete was not sensitive to gradation of aggregates . Data from the 2000 National Center for Asphalt Technology (NCAT) Test Track indicated that fine and coarse gradations had the same rut resistance . Quadis and Shweily found that unconditioned HMA specimens prepared using Basalt aggregate had
Asphalt road overlays suffer from serious cracking under heavy traffic. Basalt fibers will extend the life of asphalt or concrete pavement while allowing for less material! So if a half an inch less asphalt can be applied while having a 30-50 percent better lifespan, it is a no-brainer!
1 Introduction Hot mix asphalt (HMA) concrete is a combination of aggregate and asphalt cement. The aggregate acts as the structural skeleton of the pavement and the asphalt cement as the glue of the mixture. The mineral aggregate, including coarse and fine particles in asphalt paving mixtures, encompasses approximately 90% of volume of HMA.
