HIGHER strength compared to the bottom. A curved surface for the pavement with a slope of 1 in 36 along with side drains was recommended.Tresaugate (1764): He has proposed sloped shoulder with linear slope followed by side chains. The maximum thickness of this road was limited to 30 cm. The surface of such road was provided with very fine materials.Telford Construction: Although he had not recommended any drains alongside the pavement, he was first to advise the provision of slope in the pavement surface. The thickness varies from 17 cm at the end to 22 cm at the center for foundation stress. The wearing course in his design was provided with very fine MATERIAL for about 4 cm thickness.C.B.R Method: This method has recommended construction of pavement in numerous layers with each layer having a definite role/function in stress DISTRIBUTION and its resistance. This was the first method to CONSIDER the traffic volumes in the design of pavement.Note:Roman Method → Tresguet Design → Metcalf Design → Telford Design → Macadam Design → C.B.R Method → Modified C.B.R Method
