Bitumen emulsion is a stable dispersion of fine bitumen droplets in water, produced with an emulsifying agent. It is widely used in road construction, pavement maintenance, tack coats, surface treatments, slurry seals, microsurfacing, and selected cold mixtures. This article explains cationic and anionic emulsions, rapid-, medium-, and slow-setting grades, applications, benefits, limitations, pricing factors, and the difference between bitumen emulsion and cutback bitumen.

Polymer Modified Bitumen, also known as PMB, is a modified asphalt binder produced by adding polymers to base bitumen. It is used to improve asphalt performance against rutting, cracking, temperature variations, and heavy traffic loads. This article explains PMB applications, benefits, differences from conventional bitumen, and key pricing factors.

Bitumen 80/100 is a penetration grade bitumen used in asphalt production, road construction and flexible pavements. This guide explains its specifications, applications, standards and differences from bitumen 60/70.

Compare 40/60, 60/70 and 80/100 bitumen grades based on penetration value, hardness, flexibility, climate suitability, road construction applications and price factors.

Bitumen 40/60 is a harder penetration grade compared with bitumen 60/70. This article explains its technical specifications, applications, difference from bitumen 60/70, and key pricing factors.

Bitumen 60/70 is one of the most widely used penetration grades in asphalt and road construction. This article explains its technical specifications, applications, quality control tests, and pricing factors.

Bitumen price in Iran is not a fixed number. It depends on technical and commercial factors such as grade, quality, feedstock, exchange rates, packaging, order volume, delivery terms, and quality control. This guide explains the main factors affecting Iran bitumen price for B2B buyers.

This study examined the influence of petroleum mulch on the performance of several herbicides in weed control. Results indicated that petroleum mulch can alter soil surface conditions—such as temperature and moisture—affecting herbicide efficiency. In some cases, mulch increased herbicide persistence and effectiveness, while in others it reduced impact due to changes in penetration and distribution. The research highlights the importance of aligning mulch type and herbicide selection with proper timing and application methods.

This Utah State University research (1968) investigated the effects of petroleum mulch on tomato seed germination and yield. Results showed that oil mulch improved soil moisture retention, reduced evaporation, and enhanced soil temperature, which accelerated germination rates. Final yield (both fruit number and weight) was higher in mulch-treated plots compared to controls. The study emphasized the importance of proper mulch layer thickness and application management to maximize benefits and avoid potential seed damage.
