摘　　要：TLA改性沥青与石灰岩、方解石的粘附性试验表明:TLA改性沥青与石灰岩、方解石的粘附性均为5级。方解石属于软石,对于石灰岩中纯净的方解石应通过人工挑选的方法加以清除,对于夹杂有方解石的石灰岩应严格控制石灰岩中方解石的含量。The paper investigated the test of adhesion between TLA modified asphalt with limestone and calcite. The results show that adhesion between TLA modified asphalt with limestone and calcite are fifth grade. Because calcite is a soft stone, the pure calcite is cleared out by hand and the content of calcite in limestone is strictly controlled in the highway construction.
