The aromatic polyurethane elastomeric polymer and used along with bitumen is :

Options

A. Polyblend
B. Polyethene
C. Nylon
D. None of these

Answer

To solve the question regarding the aromatic polyurethane elastomeric polymer used along with bitumen, we can follow these steps:

### Step 1: Understand the Question
The question asks for an aromatic polyurethane elastomeric polymer that is used in conjunction with bitumen. We need to identify the correct option from the given choices: polyblend, polyethylene, nylon, or none of these.

### Step 2: Analyze the Options
1. **Polyblend**: This is a fine powder made from recycled modified plastic. It is known to be mixed with bitumen to enhance the properties of road construction materials.
2. **Polyethylene**: This is a common plastic used in various applications but is not specifically known for its use with bitumen in the context of road construction.
3. **Nylon**: This is a synthetic polymer used in textiles and other applications but does not have a known application with bitumen.
4. **None of these**: This option suggests that none of the previous options are correct.

### Step 3: Identify the Correct Answer
Based on the analysis, polyblend is specifically mentioned as being mixed with bitumen to improve its water-repellent properties and increase the lifespan of roads. This aligns with the description of an aromatic polyurethane elastomeric polymer.

### Conclusion
The correct answer is **Option 1: Polyblend**.
