Clay soils are known for their water sensitivity, which causes irreparable damage to any structure built on this type of soil.In order to avoid such problem, it is necessary to use various improvement and stabilization methods such as treatment with lime.This process has been used successfully in the field for decades.The addition of lime generates
Poly(lactic acid)/polyamide11 (PLA/PA11) blends were prepared by reactive blending with multifunctional epoxy oligomer as compatibilizer, and the compatibility of PLA and PA11 was improved.The compatibilization, toughness mechanisms, and rheological behavior of PLA/PA11 blends were studied.Positron annihilation lifetime spectroscopy (PALS) was used
