Application of bitumen penetration grade 60/70

Bitumen 60/70 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road in mild regions. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, it is used in mild areas.

Bitumen Emulsion K1-60 cationic bitumen emulsion is an emulsified asphalt containing minimum 57 % bitumen. It is a medium viscosity emulsion. Emulsion K1-60 bitumen emulsion can also be used in grouting. K1-60 cationic bitumen is made according to KS 02-769:1990 standard.

Bitumen Emulsion K1-60 are cold applied, liquid bitumen emulsions, used in the construction and repair of pavements, driveways, roads, and highways. In accordance with these standards, this product is denoted by the prefix ‘K’ signifying a cationic emulsion. The ‘1’ signifies a rapid breaking type of emulsion, while the number to the right of the hyphen indicates the bitumen content. Therefore K1-60 denotes rapid break, cationic emulsion with 57% normal bitumen content.

Bitumen Emulsion K3 cationic bitumen emulsion (medium setting) road emulsion that contains 56% bitumen, is black in color and is manufactured strictly as per KS 02-769: 1990 standard.

Bitumen Emulsion K3 are cold applied, liquid bitumen emulsions, used in the construction and repair of pavements, driveways, roads, and highways.

In many places, cutback and asphalt use is restricted to patching materials for use in cold weather cutback MC-30 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent temporarily reduces the viscosity of the asphalt for ease of handling and application. Cutback MC-30 use in the road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface. Its purpose is to bind the granular material of the base course to the asphalt layer. Usual application is by spray using a distributor.
