What is the mix ratio for mud-bound macadam pavement?

[McJames]

Mud-bound macadam pavement mix ratio is stone chips:clay:crushed stone 1:3.02:9.828. The following is relevant information about mud-bound macadam pavement: 1. Introduction to mud-bound macadam pavement: Mud-bound macadam pavement, also known as gravel pavement, is a structure formed by compacting crushed stone and gravel as aggregates with clay as filler and binder. 2. Structure of mud-bound macadam pavement: The thickness of mud-bound macadam pavement is generally 8-30cm; when the total thickness is equal to or exceeds 15cm, it is usually laid in two layers, with the upper layer being 6-10cm thick and the lower layer 9-14cm thick. The mechanical strength and stability of mud-bound macadam pavement depend not only on the interlocking effect of crushed stones but also on the binding effect of clay. Although mud-bound macadam pavement is constructed with stones of the same size, under repeated traffic loads during use, the stones will be crushed and transform into a dense gradation.
