Investigating the Relationship of As-Constructed Asphalt Pavement Air Voids to Pavement Performance

Lundi, 14 Juin, 2021 - 15:45

Several controlled laboratory studies have shown that air voids (AV) can have a large effect on the performance of asphalt pavements. AVs that are either too high or too low can cause a reduction in pavement life. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 299: Investigating the Relationship of As-Constructed Asphalt Pavement Air Voids to Pavement Performance determines the effect of in-place AVs on the performance of asphalt concrete (AC) pavements. The report is available for download from TRB at http://www.trb.org/Main/Blurbs/182244.aspx
