Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.
Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.
Specification for resealing TNZ P/4
emulsified asphalt binder, complying with TNZ M/1, Specification for Asphaltic Bitumens, is specified as the sealing binder. Where such emulsified asphalt binders are used, sealing may be carried out during any period of the year when fair, settled weather conditions are being experienced, provided there is no frost present anywhere within the
Pressure Ageing Vessel PAV, Bitumen testing equipment, Controls
The Pressure Ageing Vessel (PAV) has been developed to simulate in-service ageing of asphalt binder after 5 to 10 years. The binder is exposed to high pressure and temperature for 20 or 65 hours (selectable up to 99) to simulate the effect of long-term oxidative ageing.
Foamed Asphalt in Bituminous Paving Mixtures
viscosity of an emulsified asphalt is adjusted by the method used in preparing the emul sion, by the type of emulsifier used, and by the quantity of water added. A wide vari ety of grades of emulsified asphalts are available to meet various applications. When an emulsified asphalt is used in a bituminous mix as the binder, the need for heating

Introduction to AkzoNobel Asphalt Applications
Selection of Emulsion for Application • For each application there is an appropriate emulsion grade or grades. •The droplets in emulsions can have a positive (cationic) or negative (anionic) charge and emulsions come in three basic reactivities: slow, medium and rapid- setting •Match the reactivity of the emulsion to that of the aggregate
Asphalt Emulsions 101
The Asphalt Institute?s manual, “MS-26 -The Asphalt Binder Handbook,” defines emulsification as “a process through the use of certain mechanical and chemical processes, that allows two or more materials to combine that will not mix under normal conditions.” Emulsions are very common materials; ice cream is an example.

Product - Tip Top Tack Coat.com
The Best by test What is Tip Top Tack Coat?. Tip Top Tack Coat is high-quality asphalt emulsion tack coat for pavement bonding applications. Our Tack Coat is a specially-designed high quality undiluted product for ensuring a uniform and strong bond between layers of asphalt in road construction and for maintenance purposes.
Sometimes emulsified asphalt tack coats are diluted with water to increase the total volume of liquid while maintaining the same volume of asphalt binder within the emulsion. This can help achieve a more uniform application without applying excessive amounts of asphalt binder.
