Questions & Step-by-Step Solutions
Which material is commonly used for the base layer in flexible pavements?
Step 1: Understand what flexible pavements are. They are types of roads that can bend and flex without cracking.
Step 2: Learn about the different layers in flexible pavements. There are usually multiple layers, including the surface layer, base layer, and sub-base layer.
Step 3: Identify the purpose of the base layer. The base layer provides support to the surface layer and helps with drainage.
Step 4: Know what materials can be used for the base layer. Granular material, which consists of small stones and gravel, is commonly used.
Step 5: Understand why granular material is chosen. It is strong enough to support the weight of vehicles and allows water to drain through it.
