## Abstract

An ordinary temperature construction type hot asphalt mixture is provided which comprises an aggregate, an asphalt, a lubricative solidification material and an alkaline additive material that are mixed together, wherein the lubricative solidification material contains a fatty acid and a resin acid with a ratio of 99.5:0.5 to 80:20 as a weight ratio of “fatty acid:resin acid”.

## Claims

### Claim 1

An ordinary temperature construction type hot asphalt mixture comprising an aggregate, an asphalt, a lubricative solidification material and an alkaline additive material that are mixed together,
wherein the lubricative solidification material contains a fatty acid and a resin acid with a ratio of 99.5:0.5 to 80:20 as a weight ratio of “fatty acid:resin acid”,
the lubricative solidification material contains palmitic acid, stearic acid, oleic acid and linoleic acid including conjugated linoleic acid as the fatty acid, and
each component in the fatty acid has a content ratio of 1-6 wt % of palmitic acid, 1-4 wt % of stearic acid, 30-50 wt % of oleic acid, and 30-45 wt % of total of linoleic acid including conjugated linoleic acid.

### Claim 2

An ordinary temperature construction type hot asphalt mixture comprising an aggregate, an asphalt and a lubricative solidification material that are mixed together,
wherein the lubricative solidification material contains a fatty acid and a resin acid with a ratio of 99.5:0.5 to 80:20 as a weight ratio of “fatty acid:resin acid”,
the lubricative solidification material contains palmitic acid, stearic acid, oleic acid and linoleic acid including conjugated linoleic acid as the fatty acid, and
each component in the fatty acid has a content ratio of 1-6 wt % of palmitic acid, 1-4 wt % of stearic acid, 30-50 wt % of oleic acid, and 30-45 wt % of total of linoleic acid including conjugated linoleic acid.
