Review on evolution and evaluation of asphalt pavement

In the past decades, asphalt pavement was built stronger and stronger in terms of thickness and material quality. However, durability of asphalt pavements has not much been improved in terms of pavement design life: the design life was 20 years in the early 1960s-1970s, while it increased from 20 to 40 years in 1990s.

Estimation of Suspended Particulate Matter (SPM

The higher particulate concentration was attributed to the continuous vehicular movement of large loaded trucks transporting raw sand from mining sites to recovery plant. Maximum 232Th concentration was 0.0007±0.00013 at station 7 and minimum of 0.0003±0.00009 at station 2, which was found to be independent of particulate concentration in the
