Flexible Pavement versus Rigid Pavement

Prof. Satish Chandra, Ph. D. Director, CSIR-Central Road Research Institute, Delhi Two types of pavements are laid in India-rigid pavement and flexible pavement. In simple terms, a flexible pavement can be defined as a pavement layer comprising of a mixture of aggregates and bitumen, heated and mixed properly and then laid and compacted on a bed of granular layer.

Types of Glue - Glue Tips - Adhesive

Yellow Wood Glue: Yellow wood glue is also water based – and is made of the same vinyl acetate polymers as craft glue. It is designed to work with wood and is immediately tacky for better hold in the uncured state. It is also generally more rigid, hence it is easier to sand. Some wood glue can also be white and dry clear. Make sure to read ...
