Which grade of asphalt binder is noted for a temperature of 130-160F?

The correct answer identifies Grade CRS-1H, which is specifically formulated for use in warm weather conditions. The temperature range of 130-160°F is indicative of the conditions in which this type of binder performs optimally, as it is designed to achieve good adhesion and durability at these temperatures.

CRS-1H is a high-performance asphalt emulsion that provides enhanced properties, making it suitable for chip seal applications and surface treatments in warmer climates. Its formulation enables it to resist raveling and provide adequate flexibility, which is important for maintaining the integrity of road surfaces under heat.

Other grades listed do not fall within this exact temperature range or are suited for different conditions or applications. Each type of binder has specific characteristics and uses, but CRS-1H uniquely stands out for its effectiveness in the specified temperature range. Understanding the properties and application scenarios of various asphalt grades is crucial for selecting the right binder based on environmental conditions and pavement performance requirements.
