Porous pavements performed the worst when evaluated using standard emergy-based environmental sustainability indices and the best when using economic indices.
That is, swales perform best during a storm event with an early peak, permeable pavements perform best with a middle peak, and green roofs perform best with a late peak, respectively.
Asphalt pavements perform in a wide range of temperatures, especially in Eastern European countries, where the daily mean temperature of asphalt layers varies from −18 °C during winter to 47 °C during summer or even higher under more severe climatic conditions.
To identify how the leaching content of Na+ and Ca2+ affected efflorescence, XRD analysis of efflorescent compound on the pavement is performed.
To explore the thermo-mechanical stability of embankments in permafrost regions, an in-situ experiment of highway with asphalt pavement was performed firstly.
Tests indicate pavement-cores performed better than gyratory samples in the Hamburg.
Pavement will perform from Tuesday to Friday at Rumsey Playfield, Central Park, midpark at 70th Street; summerstage.org (sold out).
On Thursday matadorrecords.com, the Web site of the band's longtime label, said Pavement would perform on Sept. 21, 2010, at Rumsey Playfield in Central Park.
To develop proper pavement rehabilitation design within the practical constrains, pavement evaluation was performed in this study using non-destructive techniques, such as visual condition survey, falling weight deflectometer (FWD), ground penetrating radar (GPR), and dynamic cone penetrometer (DCP), and pavement coring.
In addition to mechanical testing, numerical simulations of the fatigue cracking and rutting performance of the pavement sections were performed, and the results were compared to field observations.
