One laboratory, analyzing one pcc core, blamed excessive shale in the fineaggregate for the early pccp failure. All other laboratories reported shale contents mostly under 2% and averaging closer to 1%, which meets Iowa DOT specifications. The coarseaggregate source and the two fineaggregate sources, had good service records.
This procedure covers the determination of the percentage, by mass, of a coarse aggregate (CA) sample that consists of fractured particles meeting specified requirements in accordance with AASHTO T 335. In this procedure, a sample of aggregate is screened on the sieve separating CA and fine aggregate .
HMA sections. The aggregate scctions also thawed at exponential slower rates as depth is increased from 11 to 35 days. Therefore, an aggregate surfaced road will freeze sooner and thaw slower than an HMA surfaced road. 'Thiswill effect how aggregate roads should bc managed by spring load restrictions and winter load limits.
