In 2023, construction products leader Colas partnered with biomaterials manufacturer Stora Enso to advance the application of lignin, a wood-derived renewable binder, in asphalt pavements. This is a significant technological achievement for the asphalt sector since lignin offers a renewable alternative to petroleum-based binders. Through the use of lignin in asphalt, the collaboration is looking to minimize the carbon footprint associated with pavement manufacturing and make road infrastructure more sustainable. Utilizing lignin also supports the circular economy as it is based on renewable, biodegradable materials. The new method is to pave the way for greener and more sustainable roads and harmonize with the world's movement towards eco-friendly construction practices.
In 2022, BASF introduced a new line of "smart" asphalt additives that are designed to enhance road performance and safety. The new-generation materials allow asphalt to close very small cracks on its own, greatly reducing maintenance needs and even extending the life of roads. Asphalt offers higher wear and tear resistance and higher hardness with additives, lowering long-term repair costs as well as infrastructure life overall. The innovation constitutes a technological revolution in asphalt industry and is consistent with the increasing desire for environmentally safe and affordable solutions for roads. With the overall development of the asphalt industry, the concept of self-healing asphalt represents one of the ongoing developments of materials that may satisfy the needs of modern transportation systems. With its capability to prevent expensive frequent repairs and improve road safety, these smart additives can become a valuable asset in future pavement technology.
In February 2021, Viabase, an engineered asphalt concrete, was released by Cemex UK to suit residential housing estate roads. It is designed to be perfectly adapted for those roads that are destined to endure construction traffic before they receive their final surfacing upon completion of building houses. Viabase is intended to carry heavy loads at construction age to ensure that the roads are sturdy until the point when the last layer is laid. Viabase application is part of environmentally friendly practices in the asphalt industry as it provides a more cost-saving and effective option for temporary construction. The product is also a catalyst for long-term sustainability by avoiding frequent repairs and functioning optimally during construction. Cemex UK's focus on producing quality, sustainable products like Viabase showcases its commitment to innovation and sustainable construction solutions.
The global asphalt industry has seen phenomenal growth with increasing infrastructure development and urbanization.
Growing infrastructure development projects, especially in developing economies, are driving the demand for asphalt in road construction. Urbanization, a key growth driver requires the building of new roads and upgrading of transport networks, thus increasing asphalt consumption. New technologies like warm-mix asphalt (WMA) and recycled asphalt pavement (RAP) are also growth drivers, improving the sustainability and performance of asphalt and drawing more adoption.
