By the late 18th and early nineteenth hundreds of years, new ways of highway building had been pioneered via the work of two British engineers: Thomas Telford and John Loudon McAdam. Telford's method of street constructing involved the digging of a big trench during which a foundation of major rock was set. He intended his roadways so that they sloped downwards in the centre, making it possible for drainage to occur, a major advancement on the function of Trésaguet. The area of his roadways consisted of broken stone. McAdam created an inexpensive paving product of soil and stone combination (often called macadam).
Its aim will be to decrease the motor vehicle-transmitted load so that it'll not exceed the bearing ability of your subgrade.
