What is Oxidized Bitumen? Oxidized Bitumen Export to Southeast Asia is increasingly important due to the region’s growing infrastructure needs. Oxidized bitumen, also known as blown bitumen, is a high-class product of the process in which air has been introduced into hot bitumen. This increases its softening point and resistance to water and chemical attack, […]
Intro of Blown Asphalt Blown Asphalt is produced by the Continuous or Staggered Blowing Process, where hot Penetration Grade Bitumen is blown in controlled conditions through the air in order to regulate oil content and oxidation. The resulting product has increased rubbery properties, making it more hard than its parent material. Blown Asphalt has overall […]
Intro Understanding the key differences in slurry seal vs. micro surfacing can help you choose the best pavement treatment for durability and performance. As asphalt ages and deteriorates, the treatment changes, resulting in higher treatment and repair costs. Luckily, micro surfacing and slurry sealing are pavement resurfacing techniques that can extend the life of your […]
What is Sealcoating? Seal coating is a method of protective maintenance to asphalt. The process entails putting a thin, liquid layer on top of the paved surface. It acts like a barrier in protecting the asphalt from potential UV rays damage, rain, snow, and different types of vehicle fluids. This seal coat application does not […]
Introduction Micro-surfacing is one of the most rapid methods for asphalt maintenance, which is widely used across Western Canada. The process itself is a mixture of polymer-modified asphalt emulsion, 100% manufactured aggregates, Portland cement, water, and liquid additives. A mixture is made based on technical specifications and laboratory mix design. Because it sets so fast, […]
What is a Fog Seal? Fog seal is a maintenance treatment where a thin, misty coating of asphalt emulsion is applied over a surface of existing asphalt pavement—also known as “fogging.” The low-cost process extends pavement life and delays costly repairs or full rehabilitation. Fog seals serve several important functions: they rejuvenate aged and oxidized […]
Intro Asphalt is a versatile material widely used for paving roads, driveways, and parking lots due to its cost-efficiency, durability, and visual appeal. However, not all asphalt is the same. There are different types of asphalt that serve specific purposes and are applied differently. In this article, we will explore the Hot Mix Asphalt vs. […]
Intro Cold mix asphalt, like hot mix asphalt, is a mix of aggregates; the mix is done with the addition of cutback or emulsion of bitumen. It finds application on roads carrying low traffic volume or rural areas. Cold mix asphalt is produced by emulsification of bitumen with water and an emulsifier, mixing with aggregates […]
Intro Bitumen emulsion is a mixture of bitumen, water, and an emulsifying agent used extensively in road construction and maintenance. These emulsions are classified as anionic or cationic, depending upon the type of emulsifying agent used, which dictates the electrical charge of the bitumen particles. The major differences between SS-1 and CSS-1 are based on […]
Description Slurry Seal systems (slurry seal and micro surfacing) are thin emulsion cold mixed overlays which are recognized as cost-effective restorative and preventive maintenance techniques for roadways of most traffic levels, airport runways and taxiways, highways, shoulders, sidewalks, foot and cycle paths, and parking lots. They may also be used as wearing courses on emulsion […]
