    Aug 03 32 The pavements can be classified based on the structural performance into two flexible pavements and rigid pavements In flexible pavements wheel loads are transferred by grain to grain contact of the aggregate through the granular structure The flexible pavement having less flexural strength acts like a flexible sheet eg bituminous road The following charts illustrate the average pavement life for state maintained roads For flexible pavements pavement life is defined as the number of years between resurfacings There are two main types of flexible pavements Chip Seals also called Bituminous Surface Treatments BST and Asphalt Concrete Pavements ACP
