...Roberto M. Aurilio; Mike Aurilio; Hassan Baaj Warm mix asphalt (WMA) technologies reduce the production temperature of hot mix asphalt allowing for mixing and paving at lower temperatures. As a result, the use of WMAs reduces emissions and allows for longer transport times. Because of the recent...

... modulus and phase angle of surface type mixtures using two warm mix asphalt (WMA) technologies (i.e., warm mix additive E and foaming), and two liquid antistripping agents (ASAs). A total of 20 mixtures were designed and tested. Viscoelastic master curve modeling, statistical analysis, as well...

... of secondary aging time on rutting or fatigue factors for recycled binders. The resistance of aged binders to fatigue and low temperature cracking is obviously improved by adding the warm mix asphalt additive. By comparison, using styrene butadiene rubber latex enhances the binder performance in almost all...

... materials in recent years have been used in Alaska’s pavement construction for their durability and economic and environmental benefits. These materials include modified or highly modified asphalt, warm mix asphalt (WMA), and recycled asphalt pavement (RAP). Using these materials in asphalt pavements may...

... between mixes. In this paper, a full experimental plan is designed to investigate the effect of three different factors on the dynamic modulus, namely (1) type of mix: hot mix asphalt versus warm mix asphalt, (2) impact of reheating, and (3) moisture conditioning of specimens. An open-access statistical...

... to prepare the warm mix asphalt binders, and then were aged at different temperatures and time. The softening points and contents of n-pentane asphaltene were measured. Results indicated that the softening point was improved by adding the additives. Both the softening point and content of n-pentane...

.... Fourth, the effects of varying reclaimed asphalt pavement (RAP) contents were measured for warm-mix asphalt (WMA). The overall recommendation from the research was that the Cantabro test be given serious consideration for use as a durability measurement tool for DGA mixtures. 08 05 2014 03 09...

... compactability during specimen production in the lab would be highly beneficial. While there has been significant work in defining compaction characteristics of asphalt concrete, most of this work has revolved around traditional Hot Mix Asphalt (HMA), and little work has been done with Warm Mix Asphalt (WMA...
