人们可以采用各种不同手段(如加热等)来降低沥青的稠度,以满足施工和易性的要求。此时沥青就能均匀地涂覆于石料表面,并待稠度回升后将松散的石料颗粒粘结在一起,形成沥青混合料的强度。对沥青混合料不但要求有足够的强度,而且应具备较长的使用寿命,即所谓耐久性。沥青混合料的耐久性是指沥青路面暴露 People can use a variety of different means (such as heating, etc.) to reduce the consistency of asphalt to meet the requirements of construction workability. At this point asphalt can be uniformly coated on the surface of the stone, and until the consistency of the rebound will be loose stone particles together, the formation of asphalt mixture strength. Asphalt mixture not only requires sufficient strength, but also should have a longer life, the so-called durability. Asphalt durability refers to the asphalt pavement exposed
