Concept Types of Road Pavement

iii. Stone Mastic Asphalt – same structured layer with asphaltic concrete pavement
except the wearing course is constructed with gap graded aggregate
4. Rigid Road Pavement – similar structure layer s with flexible pavement except concrete
is used as surface material.

The advantages are :

 Stronger material
 Longer service life
 Less maintenance
 However, the cost is much higher need more time before open to traffic and could
cause higher maintenance cost if defects occur
