Recommended Penetration Value of Bitumen. Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction.
Close cooperation between the paving crew and the asphalt plant is essential in producing a high quality pavement on the roadway. A fast means of communication must be established between the paving operation and the asphalt plant so that any change in the mixture production process or the roadway operation can be made promptly.

At the user's end, the outer bag is removed and bitumen along with the inner bags can be charged into the bitumen hot mix plant. During the bitumen melting process at the road construction site, the inner bag melts and completely homogenizes with the bitumen, which can be further used in the same way as conventionally packed bitumen. 4.
Recommendation to farmers about preparation of Pyrethrum pesticides : Pyrethrum powder is made with dried ground flowers. Use pure or mix with a carrier such as talc, lime or diatomaceous earth and sprinkle over infested plants. To make liquid pyrethrum extract (mix 20g pyrethrum powder with 10 l water), add soap to make the substance more ...
Oftentimes a single plant operation can feature clean asphalt with moderate viscosity in one process, and a very viscous filled-asphalt with heavy abrasives in another process. Here are some considerations: Emulsified Asphalt: Emulsified asphalt is made up of a mixture of asphalt cement, an emulsifying agent (surfactant) and water. It is ...

Grading of Bitumen- Different Methods of Bitumen Grading There are different methods of grading of bitumen such as chewing, penetration grading, viscosity grading and superpave performance grading of bitumen which are discussed in this article.
purpose of hazard identification and risk assessment in thermal power plant is to identify physical, chemical, biological and environmental hazards in the plant, analyse the event sequences leading to those hazards and calculate the frequency and consequences of hazardous events. Then risk level is assigned to
• All aspects of ‘cold’ bitumen work (such as crack sealing or jointing and road maintenance using cold mix with emulsions applied at ambient temperature) • ‘Hot’ bitumen products, which are those applied above ambient temperature. These include blending or heated bitumen binders, asphalt batch plant product,
During the coating process, the asphalt must be a liquid in order that it may spread over the surface of the particle. A Furol viscosity of about 100 seconds is believed to be the desirable fluidity for good coating. In hot-mix work, asphalt cement is heated sufficiently to produce the viscosity for good coating.
CHAPTER 3 ROAD DESIGN 3.1 Horizontal and Vertical Alignment . Center line alignment influences haul cost, construction cost, and environmental cost (e.g., erosion, sedimentation). During the reconnaissance phase and pre-construction survey the preliminary center line has been established on the ground.
Asbestos in Asphalt Explained. Asphalt is a petroleum-based substance that is commonly used in asphalt concrete and asphalt roofing shingles. Until the 1980s, asbestos was frequently used in asphalt because it was fireproof, water resistant, easy to work with and inexpensive.

Asphalt is produced in a plant that heats, dries and mixes aggregate, bitumen and sand into a composite mix. It is then applied through a paving machine on site as a solid material at a nominated or required thickness, relative to the end use. Asphalt results in a smoother and more durable asphalt road surface than a bitumen-sealed road.
