Asphalt additives are chemicals or substances that are added to asphalt to modify the final outcome of asphalt binder. Asphalt additives are materials that enhance the adhesive force between aggregates and asphalt cements preventing cracking, unraveling and deformation. Asphalt additives offers various advantages such as improved pavement performance, rutting resistance, reduced thermal cracking, reduced moisture damage and stripping resistance. Asphalt additive are generally used in road surfaces, airports, parking lots, runway, roofing, road construction and road paving. Hot mix asphalt is a mixture of approximately 95% stone, sand bound together with the help of asphalt cement, which is a product of crude oil. The asphalt cement used for binding is a heated aggregate, combined, and mixed with the aggregate at a hot mix asphalt facility.

Mix designs of asphalt additives are required to determine the grade and percent of emulsion used, as well as the workability, stability, strength and moisture. Cold mix asphalt is manufactured by emulsifying the asphalt mix with the aggregates. In emulsified state the asphalt is less viscous and the mixture is easy to work even in cold temperatures. Cold mix asphalt are ideal for road repairs as they require smaller volume. They are best alternatives to the conventional hot mix, due to their long duration storage ability. The production of cold mix asphalt is relatively eco-friendly, with very low associated emissions and reduced fuel consumption. Cold mix asphalt are environmental friendly, economical, they have a control over characteristics such as set time, mix time and strength, and they provide wide choice of processes to meet paving needs such as repair, restoration and wearing courses.
In construction industry, Asphalt is the most extensively used road construction and paving material, due to their durability and resilience. Asphalt additives are used for new construction as well as maintenance activities. Asphalt derivatives are used in formulating mortar admixtures and concrete. They also find application in manufacturing of gypsum, cement plasterboard and asphalt emulsions. Apart from this, asphalt is also commonly used as a waterproofing material for roofing applications. Various asphalt additives used in the construction industry include foaming agents, dispersants, deformers, grinding aids, accelerators and air entrainers.
Asphalt Additives Market Outlook – Need for Increasing Road Infrastructure to be the Major Market Driver.
Advances in bio-based additives such as bio asphalt binder and lignifame are expected to create opportunities for global asphalt additives market. Global market growth is assisted by rules and regulations implemented by Government agencies such as Environmental Protection Agency, which are favoring these additives. Harsh environmental factors such as rain or heat and excessive traffic load are hampering the global asphalt additives market growth. Poor quality of material used for construction and low awareness of performance enhancing asphalt additives are predicated to slow down the global market growth.
Rapid urbanization and requirement of new roads for modern infrastructure is considered as major market driver. Development of roads and infrastructure is one of the major factors contributing to the growth of geotextile market. . The industry is characterized by several major and minor participants. China, Japan, and India are expected to dominate the demand for asphalt additives. Asia Pacific is projected to witness relatively high growth in terms of value over the forecast period. Asia Pacific is one of the major contributors in the geotextile market globally, due to active growth in the construction industry. This trend is expected to be followed over the forecast period. According to IBEF India has the second largest road network in the world and is expected to reach total revenue of USD 6.9 billion by the end of 2017. India Brand Equity Foundation (IBEF) is a Trust established by the Ministry of Commerce and Industry, Department of Commerce in collaboration with the Government of India with the purpose of promoting and creating international awareness of goods manufactured in India. This mainly attributed to various government initiatives such as Pradhan Mantri Gram Sadak Yojana (PMGSY), during which 133-km roads per day was constructed in 2016-17 and others. Rise in government projects for road construction in developing countries is expected to be a positive driver for the global market.
