Segregation in Aggregate Base Stockpiles - Graniterock

Aggregate base is placed between the compacted subgrade and the concrete or AC surface layer to provide support and drainage. It is composed approximately 50% coarse and 50% fine aggregate, and its tight compaction is achieved by an even gradation and angular particle shape. Specifications for ¾″ and 1 ½″ maximum base products are provided by Caltrans Section 26. CAUSES OF SEGREGATION ...

Plant For Segregation Of Aggregates

Aggregate Segregation - Pavement Interactive. A quantitative aggregate segregation definition is less certain. Since coarse segregation is generally accepted as most destructive, a general quantitative definition is a sample ³ 10% coarser than the JMF on the 2.36-mm or the 4.75-mm sieve (Brown and Brownfield, 1988{{3}}; Cross and Brown, 1993{{9}}; Williams, Duncan and White, 1996{{8}}).

Paving Equipment – Pavement Interactive

Paving using bottom dump trucks and windrows requires a windrow elevator MTV, while other MTVs are used to provide additional surge volume, which is advantageous because it allows the paver to operate continuously without stopping, minimizes truck waiting time at the paving site and may minimize aggregate segregation and temperature differentials.
