In conventional concrete pavement design methods the design parameters are determined
using linear elastic analysis. Concrete is subject to significant size effect and as a result linear
elastic design concepts, such as ...

(South African Institution of Civil Engineering, 2014-04)
Travel along unpaved roads is not always assured, because of their low standards, poor riding quality,
impassability in wet weather, and the danger in the quantity of dust that is generated by moving
vehicles and wind. ...
