Gilsonite is a natural, resinous hydrocarbon, in mass is a shiny, black substance, but sometimes it occurs as a brownish-black color that is similar in appearance to coal or a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is used in more than 160 products, A common application of it is in bitumen blending. Laira Group offers Gilsonite with excellent quality and different sizes and meshes in the market locally and internationally.
Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and the production of asphalt pavements with superior properties, and it's very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Grades of penetration bitumen: The most popular grades are; grades 40/50, 60/70, 80/100, 85/100, and 100/120. We are also capable of producing other grades of Penetration Bitumen upon request by our customers.
Laira Group is capable of selling bitumen to its customers based on the PG method. PG is defined as polymer-modified bitumen and pure bitumen based on environmental conditions and temperature. HIGH-TEMPERATURE PERFORMANCE LOW-TEMPERATURE PERFORMANCE PG 46 -34, -40,-46 PG 52 -10, -16, -22, -28, -34,-40,-46V PG 58 -10, -16, -22, -28, -34, -40 PG 64 -10, -16, -22, -28, -34, -40 PG 70 -10, -16, -22, -28, -34, -40 PG 76 -10, -16, -22, -28, -34 PG 82 -10, -16, -22, -28, -34
To grade the bitumen-based on viscosity BIS revised IS-73-1992 specifications (Viscosity at 60 C) and as such there are four grades VG-10, VG-20, VG-30 & VG-40. A few qualification tests like specific gravity, water content, ductility, loss on heating & fares breaking point were removed from IS:73-1992 as these tests do not have any relationship with the performance of the product. Viscosity Grade Bitumen is widely used in spraying applications such as surface-dressing and paving in very cold climates. It is also used to manufacture bitumen emulsion and modified bitumen products.
Cutback Bitumen is made by reducing the viscosity of and ordinary bitumen by adding mostly petroleum-type solvent. Cutback Bitumen is used because its viscosity is lower than that of neat asphalt and can thus be used in low-temperature applications. Cutbacks are divided into three classification: Slow Curing (SC) SC-70 SC-250 SC-800 SC-3000, Medium Curing (MC) MC-30 MC-70 MC-250 MC-800 MC-3000, Rapid Curing (RC) RC-70 RC-250 RC-800 RC-3000. Laira Group offers high quality and reasonable prices, due to several years of experience in delivering Bitumen products, the Laira sales team is dedicated and understands your requirements.
Bitumen emulsion consists of three basic ingredients: bitumen, water, and an emulsifying agent. Based on specifications it may contain other additives, such as stabilizers, coating improvers, anti-strips, or break control agents. It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. Bitumen emulsions are divided into three categories in terms of setting: 1. Rapid-setting (RS) 2. Medium-setting (MS) 3. Slow-setting (SS)
