发明名称 Uniform asphalt pavement and production method therefore
摘要 A uniform asphalt pavement of substantial area composed of aggregates of varying natural qualities produced by a systematic process including mix design, mix analysis, and plant control methods. A volumetric comparison is mathematically made between blendings of coarse and fine aggregates defined over a single sieve size and a Riguez Index to determine voidage in the compacted aggregate mixture. The Riguez Index is characteristic to the particular fine aggregates used in the blending. For controlling voidage at the mixing plant, the respective quantities of coarse and fine aggregates injected into the mixing plant is controlled over the same single sieve size used for demarcating coarse and fine aggregates in mathematically computing the volumetric comparison. Further, a stability function derived from different combinations of crushed fine and blend sand, and a flexibility function derived from different mix quantities of asphalt cement provide control of flexibility and stability values.
