The relationship between overloaded trucks and corresponding economic impact on flexible pavement was investigated using HDM-4 model. Accordingly, a rational overload fine structure was prepared using optimum maintenance standards. Comparison was then made between developed rational and existing cou...

The use of core and hammer tests for determining the in-place compressive strength of hardened concrete is studied. The study consulted pertinent literature on both test methods and supported the discussion with actual field data. Although the two methods are applicable for in-place compressive stre...

It is a common practice to use empirical equations in computing engineering properties of soils in geotechnical engineering and we usually use such empirical formulae that are developed in other countries, particularly those countries found in the temperate zone. However, it is noticeable and appare...
