The method used in soil classification in road construction is the AASHTO Method.

Here are the steps to classify soil using the AASHTO Method:

1. Soil Sampling: The first step is to collect a soil sample from the construction site. This sample should be representative of the soil that will be used in the construction.

2. Particle Size Analysis: The soil sample is then subjected to a particle size analysis. This involves sieving the soil through a set of sieves of decreasing size. The weight of soil retained on each sieve is recorded.

3. Atterberg Limits: The liquid limit, plastic limit, and plasticity index of the soil are determined. These are measures of the soil's consistency and plasticity.

4. Classification: Based on the results of the particle size analysis and Atterberg limits, the soil is classified according to the AASHTO Soil Classification System. This system classifies soils into seven groups, from A-1 (most desirable for road construction) to A-7 (least desirable).

5. Evaluation: The classification of the soil helps in evaluating its suitability for road construction. If the soil is not suitable, it may need to be modified or replaced with a more suitable soil.
