摘要:This study quantified roughness for individual wavebands in the long wavelength range in pavement longitudinal profiles. Particularly, the roughness was related with quantified plausible factors associated with those wavebands. Root Mean Square (RMS) roughness defined under the P...

摘要:Abstract(#br)Pumping in pavement is defined as traffic-induced migration of saturated subgrade fines into overlying granular layers or onto the surface of the pavement, negatively impacting the performance and service life of the pavement. The objective of this study was to asses...

摘要:Abstract(#br)This study focuses on characterizing the permanent deformation of geogrid-reinforced soft soil subgrade by using the mechanistic-empirical (ME) approach based on both experimental measurements and results of numerical modeling. Two sets of small-scale pavement s...

摘要:Pavement structure typically consists of an asphalt concrete or concrete surface layer, underlying granular layers (subbase and/or base) and compacted subgrade soil layer. During wet seasons when the subgrade becomes saturated, cyclic traffic loading may result in pumping of fine...

摘要:This study focuses on evaluating the effectiveness of using various geogrid products to improve permanent deformation resistance in soft subgrade soils commonly encountered during roadway construction in Pennsylvania. Permanent deformation behaviours of the soft soils both w...

摘要:The objective of this study is to evaluate the creep compliance (D(t)) of asphalt concrete (AC) mixtures for thermal cracking prediction of flexible pavements. Various AC overlay design factors influencing the thermal cracking resistance of flexible pavements, such as mixture pro...

摘要:Abstract(#br)Particle transport and subsequent deposition in porous media play a significant role in the performance of civil infrastructure. For example, in pavement systems, the migration (also known as pumping) of fine-grained soil from saturated subgrades into subbase layers ...
