State whether the following statements are true or false: 1. Higher values of asphalt penetration test indicate softer consistency, and this asphalt is preferred for use in hot climate areas. 2. In AASHTO soil classification system, the group index (GI) is incorporated with the groups and subgroups of the soil to evaluate the type of a soil. 3. The asphalt material behaves more similar to a viscous fluid at intermediate temperatures and longer loading times.
