以新疆五一水库砂砾石坝沥青混凝土心墙为例，进行了天然砾石骨料与沥青的黏附性试验、天然砾石骨料沥青混凝土配合比试验以及压缩试验、渗透试验、小梁弯曲试验、水稳定性试验，并与碱性白云岩骨料沥青混凝土相关性能进行对比。结果表明，以水泥作为填料又兼做提高沥青与骨料黏附力的措施，可明显改善天然砾石骨料与沥青胶浆的黏附性，使天然砾石骨料沥青混凝土各项性能指标满足规范要求，且近似达到碱性白云岩骨料沥青混凝土的性能。

Taking the asphalt concrete core wall of Wuyi reservoir sand gravel dam as research object ,the adhesion ex-periment between natural aggregate and asphalt ,mixture ratio designing of natural gravel aggregate ,asphalt and concrete , compression test ,penetration test ,trabecular bending test as well as water stability test were conducted .Then the results were compared with the related data of alkaline dolomite aggregate asphalt concrete .The result suggest that cement ,as filler and the improvement medium ,can significantly improve the adhesion between natural gravel aggregate and asphalt . On this account ,the natural gravel aggregate asphalt concrete can meet the requirements of design specifications ,and it is almost as good as alkaline dolomite aggregate asphalt concrete .
