Asphalt Additives & Release Agents
Quadra offers high quality asphalt additives which optimize binder performance. These are materials widely used due to their remarkable properties which prevent cracking, pavement rutting and deformation, thus reducing the maintenance cost of asphalt structures.
Asphalt Additives
Asphalt (or bitumen as it is commonly referred to) is derived from crude oil
and is the portion which remains after distillation. Due to the varying sources and grades of crude oil, the composition of raw asphalt can vary widely. Therefore, to ensure consistency and quality, asphalt is modified with various additives. Modified asphalt is continuously faced with a requirement to enhance its performance standard in order to meet changing governmental road testing requirements. Quadra offers a number of product solutions ranging from SBS polymers to specialty additives in order to help you meet the changing performance requirements of modified asphalts.
Quadra offers products classified as Asphalt Additives including:
- Styrene Butadiene Styrene (SBS)
- Process Oils
- Sulphur Prills
- Polyphosphoric Acid
- Surfactants for Asphalt Emulsions and Adhesion Promotion
- Glycerine
ASPHALT RELEASE AGENTS FOR ROAD CONSTRUCTION & REPAIR:
Efficient asphalt release agents are necessary for a quick and smooth 
workflow in road construction & repair. Such products deliver excellent release properties to prevent unwanted sticking of asphalt to trucks, machines, rollers and hand tools.
Quadra has partnered with EstiChem, a manufacturer of unique environmentally friendly cleaners, degreasers, and lubricants
The two Asphalt focused EstiChem products, ESTICLEAN AS-VEG and ESTICLEAN AS-AQUA combines environmental compatibility with excellent release properties on metal & tool surfaces.
The use of diesel or simple mineral oils may cause the asphalt surface to be damaged should spills and over dosage occur. Diesel spills will also have a negative impact on the environment and inhalation of diesel vapours from hot surfaces creates a possible health risk to workers.
The use of biodiesel (FAME) as release agent may lead to damage of the asphalt surface from spills and damage of coatings, rubber seals, head light covers, hydraulic oil hoses and other polymer parts on the machines and trucks.
WHY USE ESTICLEAN AS-VEG?
- Excellent release effect
- No GHS labelling
- Based on vegetable oils & esters
- Environmentally friendly
- Readily biodegradable
- Ideal for road construction in water-protection areas
- Low odour
- Excellent compatibility with polymers and coatings in comparison with biodiesel
WHY USE ESTICLEAN AS-AQUA?
- Very efficient release effect
- Dilutable with water up to 1:50
- Low odour
- No GHS labels
- Based on vegetable derived components
- Environmentally friendly
- Readily biodegradable
- Reduced application rate compared the application of “pure” water
