根据Adroit Market Research，全球聚合物改装的沥青市场规模在2018年的价值为6,862.7万美元，预计到2025年，预计到2025年将达到9,805.3亿美元，在预测期内的复合年增长率为5.3％。在印度，中国，东南亚和巴西等经济体的经济发展增加，随后是政府对道路和基础设施发展项目的支持性投资，预计将在预测期内推动聚合物改装的沥青市场集中度。沥青是最古老的工程产品之一。沥青具有相当大的工业历史，因为它已在许多方面使用，包括作为粘合剂，筛选剂，防腐剂，洗涤剂和路面结合剂。制成沥青的化学成分非常复杂和可变。它与原油源和炼油厂密切相关。可以通过选择高质量的原油或合适的炼油厂来实现一些出色的沥青功能。但是，有限的石油资源以及缺乏有效的炼油厂控制措施增加了对沥青改变的关注，从而为市场带来了更好的经济利益。
不同的地板涉及对性能的不同需求。只有在技术是经济的时候，人们才能最大程度地利用自己的利益并享誉良好。在经过改性的聚合物沥青的情况下，采用聚合物时成本很高，而聚合物的数量通常会影响改性聚合物沥青的最终性能。因此，设计师必须知道在建造之前需要多么高效的道路，以及是否应该使用多少PMB。改进的特征是指如何开发和开发新鲜的其他添加剂。尽管当前使用功能和反应性聚合物在修饰沥青中的使用受到变量的限制，但在不久的将来，功能化被捕获为潜在的增长。但是，值得感知的，当功能化导致增强的聚合物 - 二杆或聚合物修饰的沥青粘附时，增加的物理相互作用似乎很容易获得和可控制。这是因为在非常升高的温度或人工炼油后，沥青和聚集体在温度升高或自然暴露于周围环境下都不是化学活性。因此，在功能化过程中的物理相互作用更简单地完成和调节。新的额外添加剂可以通过产生更有效的兼容剂，抗氧化剂和粘合剂增强剂来帮助改善聚合物改性沥青特性。 The costs of enhancing the characteristics are definitely risen, resulting in a more cost-efficient modified bitumen polymer and the extra expenses are thus allowed.
The global polymer modified bitumen market is likely to be driven by significant product consumption in Asia Pacific, Europe, and North America, during the forecast period. Asia Pacific constituted the largest revenue share of 33.5% in 2018 followed by North America. The rise in construction activities in key Asia Pacific countries such as China, India, and ASEAN is expected to boost the consumption of construction materials such as concrete and bitumen over the forecast period. Significant road construction activities coupled with a steady housing construction is expected to boost the consumption of polymer modified bitumen market over the years ahead. Support from the federal and state governments in the construction of roadways and highways, as a consequence of increasing public transits via roadways, has contributed considerably towards the growth of the construction industry in North America. Los Angeles, Vancouver, New York, San Francisco, San Jose, Toronto, Seattle, Miami, Chicago, Washington, Montreal, Ottawa, and Atlanta are some of the top cities in North America that experience heavy traffic loads.
In the U.S., a significant increase in public and private sector partnerships for highway infrastructure development has been witnessed over the recent years. In 2018, the public sector in the country spent more than US$90 billion on construction of roadways and highways. The spending value is likely to surpass US$100 bln in the next three years, with strong growth in nearly 20 states in the country. In order to sustain heavy transits, development of roadways requires use of efficient use of construction materials that not only enhance the performance of road surfaces but also the durability to sustain climatic variations. These requirements are expected to offer a favourable scope for consumption of polymers that enhance the rheology of asphalt or bitumen over the years ahead. The non-building construction sector has witnessed steady expansion in Canada since the last few years. According to Oxford Economics, the total infrastructure investments in Canada reached US$187,800 mln in the last five years.
