background: addition of disinfectant to irreversible hydrocolloid impression materials can eliminate the disinfection step to avoid dimensional changes associated with it. the aim of the present study was to evaluate the effect of various disinfectant mixing liquids on the properties of commercially available irreversible hydrocolloid impression materials. materials and methods: four commercial...

Most of previous studies employed dynamic stability test and Hamburg wheel tracking to investigate permanent deformation characteristics asphalt concrete (AC) layer. However, the performance only focuses on surface course neglected influence middle layer base course. The present study investigates four (4) different configurations flexible pavement analyzes contribution AC total as response var...
