Despite its rugged exterior, asphalt is somewhat of a sensitive guy—to heat that is. But thankfully there are methods to grapple with this. Like many construction materials, common types of asphalt have a goldilocks temperature zone within which it is optimal to shape. Most asphalt is best laid and compacted between 180 degrees to 225 degrees. But the hotter the better when it comes to compaction, the process that squeezes asphalt’s aggregate materials together with its binder to give it shape and rigidity. If the substance gets cooler than 180 degrees, it will merely flatten out when rolled and will not become denser like it should. This means it will not properly compact and its structural integrity should be called into question. For the best application, J&W likes to stick to days when weather is cooperating if possible. Rain and heavy wind and the direction of sunlight are at play, particularly in the colder months of the operation season—October and November. To combat these challenges (year-rou ...
