Abstract:

The Louisiana Department of Highways specifications on asphaltic concrete allow the contractors to use silos or surge bins for storage of asphaltic concrete mixtures. However, the maximum allowable storage time of the hot mix, if the contractor elects to use such a facility, is set up arbitrarily. The present allowable time for heated silos is established according to the maximum size of aggregate in the mix and the type of heating system used in the storage facility. For unheated surge bins, the maximum allowable storage time is two hours. ; This study was initiated to seek data relative to the effects of storage time and temperature on the physical properties of asphaltic concrete. however, temperature was considered a major criteria for storage time. ; The scope of the study was confined to unheated surge bins at a hot mix plant during a late summer period. The mixture evaluated was a wearing course sand-gravel mix with 3/4 inch maximum size aggregate.
