Motorway Construction, Project Execution PlanDetails of how a Motorway is constructed, and how the progress, safety and quality will be monitored and controlled. Also the measures to ensure that the site is environmentally friendly.

Brief Description

The purpose of this presentation is to give an understanding of the Methods, Plant and Sequence to construct a Motorway.

This presentation can be used to engage Stakeholders and to get the Site Teams commitment to the programme. Also can be used for Induction Training and as a way to capture and share knowledge.

Project Execution Plan (PEP) details how aproject will be executed, monitored and controlled.

High in Educational Value and easily understood. Recommended for Continuing Professional Development (CPD)

A concrete mix contains 5 major

elements: cement, water, coarse

aggregates, fine aggregates (sand) and

air in different proportion. Additional

elements such as pozzolanic materials (fly

ash, silica fumes or slag) and chemical

admixtures can also be incorporated to

the mix to increase its properties.

Concrete batching plant comprises - concrete mixer, control cabin, silos for cement and fly ash, aggregate bins and conveyor belt system to feed the mixer. Also aggregate storage bays and water storage tanks. The mixing is computer controlled and has a dynamic screen display, showing the process. Material storage capacity to match two days concrete production

Reinforcement Bent to Shape by Bending Machine Reinforcement that is cut and bent is Bundled for delivery to work site

Asphalt Batching Plant

The plant is used for the manufacture of asphalt. Aggregates, sand and a filler (such as stone dust), in the correct proportions, are heated, and coated by mixing with a binder, bitumen based. The temperature of the finished asphalt mix must be sufficient to be workable after transport to the final destination.
