Subject(s): Abstract: PSDs and interlocking of aggregates are probably the most significant factors associated with the mechanical performance of UGMs. This project will investigate to optimize the PSDs of UGMs applying Olard’s method and will compare the performance with UGMs having standard PSDs. Furthermore, the performance of open graded UGMs with different PSDs will be investigated to obtain material with better drainage properties and reduced moisture and frost susceptibility.Abstract: PSDs and interlocking of aggregates are probably the most significant factors associated with the mechanical performance of UGMs. This project will investigate to optimize the PSDs of UGMs applying Olard’s method and will compare the performance with UGMs having standard PSDs.
