asphalt mixes
The properties, advantages and disadvantages of asphalt mixes such as Marshall and Superpave mixes and the way they are best applied.
Asphalt plant operators extract raw materials such as sand and stones and operate mobile equipment for their transport to the plant. They tend automated machines to crush and sort out stones, and to mix the sand and stones with asphalt cement. They take samples to check the quality of the mix and arrange for its transport to the construction site.

The properties of different materials developped in a laboratory, their usage per type of products, and how to create them.
Different types of asphalt covering, based on their bitumen content and composition. The strengths, weaknesses, and price points of each type. Special properties such as porosity, resistance to skidding and noise characteristics.
Tend the machines which mix asphalt solution feeding it with the already processed minerals, bitumen and additives according to the formula.
Operate a variety of machinery used to separate raw mineral for further processing based on size of particles or chemical composition. Work with screens, flotation cells, spirals, jigs, drums and cyclones.
Operate equipment used to reduce the size of raw minerals to prepare it for further processing. Work with gyrotary and jaw crushers, and roll, ball and autogenous mills.
Segregate into batches the raw materials to be further processed.
Weigh materials and products, record weight and other relevant data on tags or labels.
Measure and adjust temperature of a given space or object.
Insert raw materials, chemicals and processing agents into plant machinery.
Continuously check up on the automated machine's set-up and execution or make regular control rounds. If necessary, record and interpret data on the operating conditions of installations and equipment in order to identify abnormalities.
Prepare and measure the basic materials that are needed to produce goods and finished products.
Keep records of the machine's faults, interventions and irregularities for quality control.
Set up and give commands to a machine by dispatching the appropriate data and input into the (computer) controller corresponding with the desired processed product.
Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.

Receive raw materials from the suppliers. Check their quality and accuracy and move them into the warehouse. Make sure that raw materials are adequately stored until they are required by the production department.
Maintain the cement mixing truck by greasing the rollers and checking the oil and antifreeze levels.
Evaluate how much stock is used and determine what should be ordered.
Operate or tend furnaces such as gas, oil, electric to heat treat castings in order to reach the correct mechanical properties. Adjust furnace controls to heat parts the prescribed time to the right temperature.
Bring construction materials, tools and equipment to the construction site and store them properly taking various aspects into account such as the workers' safety and protection from deterioration.
Perform cleaning routines after equipment use.
Collect samples of materials or products for laboratory analysis.
Drive movable heavy equipment used in construction. Load the equipment onto low loaders, or unload it. Judiciously drive equipment on public roads when required.
Monitor activities and perform tasks ensuring compliance with standards involving environmental protection and sustainability, and amend activities in the case of changes in environmental legislation. Ensure that the processes are compliant with environment regulations and best practices.
Maintain records of the progress of the work including time, defects, malfunctions, etc.
Conduct activities associated with determining the itineraries and loading of bulk trucks.
Work with concrete mixer trucks. Drive the truck and operate controls. Keep track of time. Take the necessary steps to evacuate the concrete upon arrival at the site, either alone using a full range chute, or with help when using a rear chute.
Perform regular maintenance, possibly including corrections and alterations, on a machine or machine tool to ensure it remains in a proper productive state.
Test processed workpieces or products for basic faults.
Record data which has been identified specifically during preceding tests in order to verify that outputs of the test produce specific results or to review the reaction of the subject under exceptional or unusual input.
Maintain required company records and forms in order to report any defective materials or questionable conditions of manufacturing machinery and equipment.
Stack goods and manufactured products into containers. This may include anticipating the need for and utilising additional protective materials in stacking the products.
Tend packaging machines such as filling, labelling, and sealing machines. Stock and sort products to be processed according to specifications. Replenish packaging supplies as required, such as boxes, cartons, wrapping paper, plastic sheet, glue, ink, or labels.
Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.
Write reports on the manufactured batches history taking into account the raw data, tests performed and compliance to Good Manufacturing Practices (GMP) of each batch of product.
