The mastic asphalt mixture (MA) is one of the first mineral and asphalt mixtures used in history. Its composition and structure allow it (the mixture) to be produced both in industrial conditions (in mineral and asphalt mixing plants) and in field conditions-in mobile boilers (especially when the produced mixture is used to repair damaged surface). The high proportion of the sand fraction makes the mixture highly workable, allowing it to be laid/incorporated without special equipment. MA, however, also has some drawbacks. The asphalt content is higher than in other mixtures, which can make it prone to plastic deformation. Mastic asphalt requires higher processing temperatures than other "hot" mixtures. Mastic asphalt mixtures are installed as road pavement layers and, because of their high density, as the protective layer on roof felt isolation on bridge decks. The high temperature of embedding creates a risk of damaging the roof felt, as its typical temperature resistance is lower than 180 °C, whereas the temperature of the mastic asphalt mixture is higher. The use of zeolites can enable reconciliation of technological requirements of mastic asphalt and asphalt roof isolation. The mixes MA 8 and MA 11 containing 0 and 5% of two types of zeolites and asphalt binders 35/50 or elastomer-SBS-modified asphalt binder PMB 25/55-60 were used in the research. Laboratory tests revealed that the addition of a 5% amount of zeolite by asphalt mass makes it possible to reduce the mastic asphalt laying temperature by up to 30 °C, which seems to be very important from ecological, economical, and pavement durability points of view.
玛蹄脂碎石混合料（MA）是历史上最早使用的矿物与沥青混合料之一。其成分和结构使其（混合料）既能在工业条件下（在矿物和沥青搅拌厂）生产，也能在现场条件下——在移动锅炉中生产（特别是当生产的混合料用于修复受损路面时）。砂料所占比例高使得该混合料具有很高的可加工性，无需特殊设备就能铺设/掺入。然而，玛蹄脂碎石混合料也存在一些缺点。其沥青含量高于其他混合料，这可能使其易于发生塑性变形。玛蹄脂碎石混合料需要比其他“热”混合料更高的加工温度。玛蹄脂碎石混合料被用作道路路面层，并且由于其高密度，还被用作桥面屋顶毡隔离层上的保护层。嵌入时的高温会产生损坏屋顶毡的风险，因为其典型的耐热温度低于180℃，而玛蹄脂碎石混合料的温度更高。使用沸石能够协调玛蹄脂碎石混合料和沥青屋顶隔离的技术要求。研究中使用了含有0%和5%两种类型沸石以及35/50沥青结合料或弹性体 - SBS改性沥青结合料PMB 25/55 - 60的MA 8和MA 11混合料。实验室测试表明，按沥青质量添加5%的沸石可使玛蹄脂碎石混合料的铺设温度降低多达30℃，从生态、经济和路面耐久性的角度来看，这似乎非常重要。
