What is the mix ratio for mud-bound macadam pavement?
2 Answers
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.
I remember once driving back to my hometown on a muddy gravel road, which was very bumpy with the tires humming. The typical mix ratio for such roads is about 70% gravel and 30% soil, compacted firmly with water to ensure durability. As an experienced driver, I've found that this type of surface not only makes the car prone to slipping but also increases fuel consumption and accelerates tire wear. For example, gravel roads put a heavy burden on the suspension system, requiring maintenance over time to prevent squeaking noises from the chassis. I suggest fellow villagers drive slowly on rural roads and maintain stable tire pressure to save money and avoid trouble. On better roads, fuel consumption can decrease by around 10%, and comfort improves significantly.
