WITOS Paving Plus - Application modules

:



Scope of functions:

▪ Planning of all pavers, equipment and

rollers in a timetable

▪ Co-ordination with the asphalt plant

output and calculation of just-in-time

parameters, such as the lorry

schedule

▪ Enables simple and uncomplicated

rescheduling

WITOS Paving Plus - Control

Simple and transparent planning

Benefits:

▪ Clear presentation of all construction work (job files)

▪ Simple machine planning through Gantt charts increases transparency

▪ Planning errors can be seen directly, consistent comparisons are carried out

▪ Displays the work progress and considers it in the planning of follow-on lots.

:



Scope of functions:

▪ Organizes the supply chain to the job site through target arrival times

▪ Visualizes the mixing plant output and the supply of materials to the job site

▪ Provides information about the lorry: material, status, delivery note

▪ Displays current messages

▪ Messenger functions

Stears just in time delivery at mixing plant

Benefits:

▪ Enables the mixing or weighing supervisor to organize just-in-time delivery to the job site

▪ Facilitates communication with the job site, particularly in the event of deviations from plan and the problem of residual quantities

▪ Continuous information about the progress of construction and the status of the lorries

▪ Indication of mixing plant ratios and the current loading capacity per hour

Tracking of truck positions - Jobsite and Materials

Monitor trucks on their way to the jobsite and back to the asphalt plant

:



The functional scope:

▪ Visualization of all important planning data of a job site section

▪ Display of target and actual values in terms of duration, paved distance and tonnage

▪ Update of work progress in real time

Benefits:▪ Deviations from the plan are detected early on ▪ Counter-measures can be taken in good time▪ Paving errors and surplus consumption are recognised directly

Jobsite progress information in the paver terminal

WITOS Paving Plus - Paver terminal

:




▪ All loaded vehicles are listed in a table with tonnage and the arrival times

▪ Unloaded lorries are booked, the mass balance is automatically updated

Benefits:▪ Visualizes the time at which the lorry will arrive on the job site▪ Shows the installed and the outstanding material quantity as well as tonnage on the way to the job site▪ Allows the pave speed to be reduced in order to delay stopping a paver

Material supply - transparent through virtual supply chain


:




▪ Measurement of the built pavement through modern infrared camera.

▪ Simple visual checks of the paving quality.

Temperature information -> quality control.

Benefits:▪ Increase in paving quality through accurate evaluation of the temperature ▪ Checks with no extra effort during ongoing operation▪ Easy data retrieval via the WITOS Paving “Jobsite” module on the paver operator’s console ▪ Basis for constant improvement


:



Scope of functions:

▪ Analysis of the process chain: manufacture, logistics and paving

▪ Convenient analysis and key figure calculation

▪ Chronological documentation of events (temperatures, unloading, standstill)

▪ Events shown on maps

Extensive analyses available after construction work.

Benefits:▪ Objective assessment of construction processes through key figures and analyses▪ Possibility of saving and using experience values to promote best practice approach▪ Ensures constant improvement of future construction projects through the PDCA cycle▪ Key figures are included in the calculation
