Key Benefits

• Quality Control & Quality Assurance documentation• Increased Operator Productivityp y• More Efficient Jobsite• Confidence in Results

Global Paving

Quality Assurance & Control

• Documentation of work completed – Number of passes tied to position– Stiffness results tied to position

• In-process control– Ability to monitor progress daily or near real-timeAbility to monitor progress daily or near real time

• Electronic storage of results– Analysis with desktop or laptop computers

Historical record of job site data• Historical record of job site data– Correlate with long-term results

Global Paving

Quality Assurance & Control

• Delivers a map of the entire compacted area

• Reduced number of manual compaction tests– Lower testing costs with fewerLower testing costs with fewer

samples to tag and store

Global Paving

Increased Operator Productivity

• Visually displayed compaction value – Helps the operator determine if the soil

has reached its target stiffness – Takes the guesswork out

of compaction measurement

• Real-time data for operator– Amplitude, frequency, speed,

number of passes

• Empowers the operator withreal-time results

– Identify soft spots and pinpoint location to excavate– Indicates potential moisture content issues – Can check final grade with RTK GPS (as built condition)

Global Paving

More Efficient Jobsite

• Manpower efficiencies– Work areas that need more

compaction– Get off areas that are

compactedMi i i– Minimize passes

– Optimize fuel use

• Real-time testing – Eliminates the need to stop

and wait for results– Production remains at a

t t l lconstant level

Global Paving

Confidence In Results

• Identify compaction problems– Fix them early in the construction

process– Reduced threat of rework

• Elimination of need for a test roller– Reduced transportation costs– Less equipment to maintainq p

• Highly accurate GPS provides exact location on job site

AccuGrade® for Asphalt Compaction

Why AccuGrade?Why AccuGrade?It’s simple, we want to help contractors build better roads and

make more money.y

The Cat AccuGrade system helps contractors increase efficiency and productivity while recording data for quality control d t ti d f t l i Th t h ldocumentation and future planning. The system can help eliminate the second-guessing that occurs throughout the day by providing a real-time visual reference of the pass-count and asphalt mat temperature.

Eliminate Second-Guessingate Seco d Guess g

• Where did I stop on the previous pass?• Where did I stop on the previous pass?• Did I go back far enough on the return pass?• Did I provide enough overlap on the previous pass?• Is the mat temperature too hot, too cold?

• Operator can see where he/she is on the mat and how many passes have y pbeen made

• Operator can determine when to begin rolling and when to end, based on mat temperatureon mat temperature

• A warning indicator alerts the operator if the asphalt temperature exceeds or falls below the target temperaturetemperature

GPS Receiver and Angle Sensor• Receiver and angle sensor are mounted to the ROPS with a heavy-duty bracket.

• Receiver accepts satellite signals for precise horizontal and vertical positioning.

• Angle sensor measures the left/right tilt ofAngle sensor measures the left/right tilt of the machine, ensuring positional accuracy of the GPS receiver.

Global Paving


GPS Radio• Radio is mounted on the ROPS of the

machine to ensure maximum signal reception.

• It receives real-time Compact Measurement Record (CMR) data from the GPS base station radio for calculating high-accuracy GPS positions.

• Also provides a two-way wireless radio network between the machine and Accugrade Office Software for complete real-time analysis.

Global Paving


Temperature Sensors• Infrared temperature sensors mounted to pthe front and rear of the machine • Provide real-time readings that allow the operator to determine when optimum compaction conditions existcompaction conditions exist. • The temperature from the lead drum is automatically delivered to the display.

• Upper limit that permits compaction -around 149° C (300° F)• Lower limit that permits compaction -

around 85° C (185° F) ( )

Pass-Count MappingThe colors signify the number of times that theThe colors signify the number of times that the drums hit a specific area.

Green – Target pass-count (3) was met

Blue – Target pass-count not met; 1 more pass needed

Red – Target pass-count not met; 2 more passesRed Target pass count not met; 2 more passes needed

* Note: The red slivers within the paved areas indicate that there wasn’t proper drum overlapindicate that there wasn t proper drum overlap

Global Paving


Why Should I Care About Pass-Count Mapping?Pass-Count Mapping?

Pass-count mapping helps achieve target density and increases roller efficiency.

• Eliminate excessive overlap• Prevent incomplete passes stopping short• Prevent incomplete passes, stopping short • Maximize coverage• Easier night-time operation

Global Paving


Temperature MappingThis illustration provides asphalt temperatures as the roller passed over the fresh mat. The color pattern signifies the different temperature ranges that were present.p

Green – Target temperature metBlue – Target temperature met, lower range than green gRed – Temperature below target,

Note: These marks were for testing purposes.

Global Paving


Why Should I Care About Temperature Mapping?Temperature Mapping?

Temperature mapping helps operators determine when the asphalt is acceptable to

ticompaction. • Upper temperature limit that permits compaction is normally around 149° C (300° F)

• Lower limit that permits compaction is normally around 85° C (185° F)

• Avoid “tender zones” if one is present

Why Quality Control?High material costs require getting it right the first time.

Quality control helps develop procedures that ensure the results exceed customer

i t brequirements by: • Maximizing density and bonus payments• Providing documentation for federal, state and local officials• Delivering documentation for future planning• Verifying process performance
