A quick guide to the different types of asphalt
Cold mix asphalt is a mixture of hot asphalt and cold aggregate. It’s used as a base for new road construction because it’s easy to work with and can be poured quickly. It’s also less expensive than other types of asphalt, making it a popular choice for roads in the lower cost regions of the country.
There are four main types of cold mix asphalt: modified, permeable, reactive, and semi-reactive. Modified cold mix asphalt is the most common type, and it’s made up of about 60% hot asphalt and 40% cold aggregate. Permeable cold mix asphalt is similar to modified cold mix, but the proportion of hot asphalt to cold aggregate is greater. Reactive cold mix asphalt is made up of about 30% hot asphalt and 70% cold aggregate, and semi-reactive cold mix asphalt has about 20% hot asphalt and 80% cold aggregate.
