STAR—SEAL是一种重质精练煤焦油封层材料.其混合料又称为“美国1号配方”。由于其含有煤焦油沥青、矿物填料和表面活性剂,在沥青路面上喷涂STAR—SEAL后,会在表面形成一层精练煤焦油沥青乳胶保护层,坚韧耐用且有弹性,将极其重要的油分和增塑剂锁定在沥青混凝土中,从而保护沥青路面不受气候、水、盐、气体和其他石化制品等有害因素的破坏。其主要功能有:保护沥青不受强紫外线侵蚀而老化;保护沥青混凝土不受水侵蚀:阻止汽汩,柴油和其他石化制品侵蚀沥青路面;便于沥青STAR—SEAL路面的清洗;恢复路面抗滑性能到优良状况;均一的深碳黑色,明显改善了路面视觉效果。
STAR-SEAL is a highly refined coal tar seal material which is also known as “US Formula 1”. Due to its coal tar pitch, mineral fillers and surfactants, STAR-SEAL is sprayed on the asphalt pavement to form a layer of refined coal tar pitch latex protective layer on the surface. It is tough, durable and flexible. It combines extremely important oil and Plasticizer locked in asphalt concrete, thus protecting the asphalt pavement from the harmful effects of climate, water, salt, gas and other petrochemical products. Its main functions are: to protect the asphalt from aging by strong UV rays; to protect the asphalt concrete from water erosion: to prevent steam, diesel and other petrochemical products from attacking the asphalt pavement; to facilitate the cleaning of the asphalt STAR-SEAL pavement; to restore the anti-slip performance of the pavement To good condition; uniform dark carbon black, significantly improved the visual effects of the road.
