2021-2-16 HOT MIX ASPHALT WHAT IS HOT MIX ASPHALT? Hot mix asphalt may be referred to by several names. In different sections of the state it may also be referred to as bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total

2020-10-13 Permeability of Hot Mix Asphalt Concrete as Affected by Binder Content . Joseph A. Giompalo . One of the primary objectives when constructing hot mix asphalt concrete (HMAC) is achieving the target density in order for the pavement to be impermeable. If the density is too low, water infiltration causes pavement damage from freeze-thaw and

Abstract. Based on the research of ultra-thin asphalt concrete, this paper brings forward a new kind of pavement material named Easy-Compact Hot-Mix Asphalt (ECA). ECA-additive and polyester fiber are adopted to produce asphalt mixtures, and various lab tests are undertaken to evaluate the effects of these additives on asphalt mixture performance.

2016-10-13 Hot mix asphalt pavement is a mix of mostly stone, sand or gravel that is blended with an aggregate of asphalt cement. The asphalt cement is mixed at a high temperature and then laid down layer-by-layer to create a pavement structure. It is used for main roads and highways because it is highly durable and therefore, it can handle the high ...
