摘要：
Hot rolled asphalt as used in the UK is surfacing material with about one hundred years history. Modern HRA wearing course material has several advantages over continuously graded macadams, for: (1) its gap-graded nature, with a high proportion of fines giving a large surface area, can contain more bitumen than coarser materials, and this higher volume of water proof 'glue' helps durability; (2) the workability of HRA is high, giving good compaction characteristics; (3) its pore structure results in a virtually impermeable layer; (4) its strength in tension, as measured by fatigue resistance, is high.
